Tomato pomace (TP) is an underutilized source of bioactive compounds with potential application in the food sector. A factorial experiment was designed to compare three culinary techniques, Thermomix®, Roner®, and traditional pan-frying, for the preparation of tomato sauces, enriched or not with TP, applying two temperatures and two cooking times. A multivariate analysis was performed on all the results obtained for the metabolites. The addition of TP significantly increased the content of bioactive compounds, especially phenolic compounds. OPLS-DA models were generated using cooking technique, temperature, and time as discriminant factors. The cooking technique had a greater effect on the phenolic content than cooking temperature or time. Thermomix® released bioactive compounds from the tomato into the sauce to a similar extent as pan-frying. Roner® proved to be effective in preserving the volatile fraction of the sauce. The Thermomix® significantly increased the amount of bioactive compounds, while the Roner® increased the volatile compounds. [ABSTRACT FROM AUTHOR]

This work aims to address the knowledge gap in the thermal efficiency performance of a locally made cookstove in Mali. Despite the fact that the thermal efficiency of cookstoves is a crucial aspect of cooking, the performance of commercially produced cookstoves in Mali has not been thoroughly studied. In this context, the thermal efficiency of a single-mouth biomass stove has been investigated using a theoretical and experimental approach. First, the fundamental principles of physics for the three forms of heat transfer were applied. Then, the theoretical thermal efficiency of the stove was calculated based on the percentage share of energy gains and losses for the respective heat transfer modes. This analysis shows that the highest energy gain is achieved by radiation heat transfer from the flame and the fuel bed, followed by convection heat transfer to the bottom and sides of the pot, respectively. In order to validate the findings, the theoretical results have been compared with the experimental data at a case study site in Katibougou, Mali. Accordingly, the experimental thermal efficiency is slightly lower than the theoretical value, with a measured value of 27% compared to the theoretical value of 31.45%. The theoretical thermal efficiency can be closer to the experimental efficiency if the combustion losses caused by incomplete combustion of the fuel are taken into account. [ABSTRACT FROM AUTHOR]

Indoor environments pose a significant health risk due to exposure to particulate matter (PM), leading to various diseases and premature deaths, and raising public concerns about indoor air quality. Household kitchens are a major contributor to indoor air pollution, emitting particulate matter of varying sizes during cooking, which disperses throughout the house. Understanding the extent of PM exposure and identifying its sources is crucial. This study assesses PM presence in Kuwaiti household kitchens, measuring concentrations of different‐sized particles (PM 0.3, 0.5, 1.0, 2.5, 5.0, and 10 μm) under various conditions. Measurements were taken for 24 h using a particle/mass monitor device, considering different ventilation scenarios, cooking oils, and methods. Spearman's rank correlation and indoor/outdoor (I/O) ratios investigate the correlation between indoor and outdoor PM exposure. Principal component analysis (PCA) models identify specific sources contributing to PM exposure. A questionnaire survey in Kuwaiti households determines primary kitchen sources during cooking. Results show that kitchens with ventilation systems consistently reduce PM concentrations. PM emissions during cooking vary based on factors like cooking method, energy type, cooking oil, food, additives, temperature, and ventilation. The cooking stove is the primary emission source, but other household activities contribute. This study enhances our understanding of influential factors affecting cooking emissions and their concentrations, contributing valuable insights into mitigating indoor air pollution.

A secondary aim was to evaluate preliminary programme effectiveness. Method: Participants were recruited through a disability service provider. Feasibility measures were: recruitment and retention; implementation; engagement and participation; adverse outcomes; and feasibility of outcome measures. Acceptability was assessed using an interactive process evaluation. Effectiveness measures included cooking frequency, cooking and food skill confidence and diet quality. Results: Six of eight participants completed the intervention with high attendance and programme engagement. FLIP was well received by participants and support workers. No adverse outcomes occurred. Diet quality was feasible to assess. Conclusions: Findings can inform content, delivery and evaluation of future culinary nutrition programmes for adults with mild‐to‐moderate intellectual disability. [ABSTRACT FROM AUTHOR]

Laser food processing has the breath-taking potential to revolutionize the industry in many aspects. Among the different laser configurations, CO2 laser has received special attention due to its relative high efficiency in power generation, its high-power output and its laser beam wavelength, infrared, which is strongly absorbed by water, the main component of food materials. Over the last 50 years, different uses of CO2 laser for processing foods have been proposed so far, including cooking, broiling and browning, selective laser sintering, marking, microperforation for improving downstream mass transfer operations (e.g. infusion, diffusion, marinating, salting, drying, extraction), cutting and peeling, and microbial surface decontamination. The present work is a review of the state of the art of the use of CO2 laser for food processing that covers the main characteristics and mechanisms of this technology, as well as the most important published results regarding its applications in the agri-food sector, highlighting the main challenges to bring out its full potential in the coming years.

Solid biomass dominates as the primary source of cooking energy, especially in rural households of Nepal. The use of solid biomass has a detrimental effect on health, exacerbates the burden of biomass collection, and hampers access to clean energy. Understanding the factors influencing the choice of modern cooking fuels is crucial to improving energy security and resilience and easing the transition to clean fuels. This study evaluates technological choices for the transition in cooking energy from the perspective of experts working in the government, non-government, and academia sectors. A structured questionnaire survey was prepared with five criteria and nine cooking technology options. Fifty-one experts responded to the survey, and their responses were analyzed using the analytical hierarchy process. The study reveals that efficiency and capital cost are the primary criteria for selecting cooking technology. The most suitable clean cooking technology is an induction stove followed by a hot plate, while the least preferred technology is a Bayupankhi stove followed by two-pothole mud improved cooking stoves. To ensure the robustness of the method, sensitivity analysis was performed on the two primary criteria efficiency and capital cost of the cooking technology. The analysis revealed robust and consistent rankings of technologies. This study should help create a conducive environment for relevant stakeholders and policymakers to formulate and implement relevant policies and strategies to accelerate the cooking energy transition in Nepal.

Vegetables and legume soups contain various essential and bioactive constituents such as vitamin C, carotenoids, and phenolics. Antioxidant activity characteristics related to those compounds are well known to contribute profusely to human health. The cooking technique affects the bioavailability of nutrients and bioactive compounds, making it crucial to explore optimal alternatives to maximize them. The objective of this study was to explore the influence of different cooking techniques (boiling, pressure cooking, sous-vide, and cook-vide) on the physicochemical properties and bioactive characteristics of a ready-to-eat vegetable lentil soup. For this, the bioaccessibility of those compounds was assessed through an in vitro simulated gastrointestinal methodology. The firmness of vegetables was established to define treatments' cooking times, allowing subsequent comparison of the nutritional and functional properties of the soups. The color of vegetables was also evaluated as a quality parameter, which contributed to providing a global vision of the process impact. The results revealed that in vitro digestion (IVD) caused a decrease in all bioactive compound determinations for all cooking treatments of up to 72% for total phenols, 92% for lycopene, 98% for carotenoids, and 100% for vitamin C. Additionally, the antioxidant activity of the soups after thermal treatment improved up to 46% measured by the DPPH method. This study emphasizes the importance of considering the digestion process in the selection of the most adequate cooking technique. After IVD, traditional cooking (boiling) reached the maximum total carotenoid and lycopene contents; cook-vide and pressure-cooking techniques provided the highest total phenol content, showing these three techniques to have the maximum antioxidant capacity.

Deficits in executive functions (EF) are strongly related to real-life functioning and negative symptoms (NS) in schizophrenia. Recently, virtual reality has enabled more ecologically valid approaches to assess EF in simulated "real-life" scenarios among which the virtual cooking task (VCT) has gained attention. However, the clinical implications of the VCT in schizophrenia have not been investigated exhaustively. In this study, clinically stable individuals with schizophrenia (n = 38) and healthy controls (n = 42) completed a novel VCT and a set of computerized standard EF tools (CST) to primarily investigate concurrent and discriminant validity. In addition, the study explored links between EF assessments, functioning, and NS while controlling for antipsychotic intake, clinical stability, and age. This VCT consisted of four tasks with increasing difficulty and time constraints. The most relevant findings indicate that (1) the VCT showed moderate to strong correlations with CST, (2) the VCT discriminated EF performance between both the groups, (3) the VCT predicted interpersonal functioning, and (4) the VCT predicted NS in greater extent than CST. Accordingly, the findings give support to the concurrent and discriminant validity of the VCT to assess EF and indicate its value to deepen the study of collateral functional deficits and NS in schizophrenia.

This article explores the concept of nomadic material culture in ancient Eurasia and its significance in archaeological research. It challenges traditional approaches that focus on identifying specific ethnic groups based on artifacts and instead emphasizes the relationships between people and objects. The article also critiques the use of ancient texts as a source for archaeological interpretation. It argues for a broader definition of nomadism that includes various forms of residential mobility. The special issue delves into the motivations for mobility and the technological innovations associated with nomadic material culture. The article specifically examines the technological advancements and cultural importance of material culture among the Scythians, highlighting modifications made to artifacts for mobility and the advanced metalworking skills of Scythian artisans. It also discusses how material culture reflects cultural identity, social organization, and interactions between mobile and sedentary communities, as well as environmental adaptation. The article ultimately emphasizes the significance of studying material culture to gain a deeper understanding of nomadic peoples and challenges the perception of them as transient or peripheral.

BACKGROUND: Seafood consumers are widely exposed to diclofenac due to the high contamination levels often present in aquatic organisms. It is a potential risk to public health due its endocrine disruptor properties. Limited information is available about diclofenac behavior after food digestion to enable a more realistic scenario of consumer exposure. This study aimed to evaluate cooking effects on diclofenac levels, and determine diclofenac bioaccessibility by an in vitro digestion assay, using commercial fish species (seabass and white mullet) as models. The production of the main metabolite 4′‐hydroxydiclofenac was also investigated. Fish hamburgers were spiked at two levels (150 and 1000 ng g−1) and submitted to three culinary treatments (roasting, steaming and grilling). RESULTS: The loss of water seems to increase the diclofenac levels after cooking, except in seabass with higher levels. The high bioaccessibility of diclofenac (59.1–98.3%) observed in both fish species indicates that consumers' intestines are more susceptible to absorption, which can be worrisome depending on the level of contamination. Contamination levels did not affect the diclofenac bioaccessibility in both species. Seabass, the fattest species, exhibited a higher bioaccessibility of diclofenac compared to white mullet. Overall, cooking decreased diclofenac bioaccessibility by up to 40% in seabass and 25% in white mullet. The main metabolite 4′‐hydroxydiclofenac was not detected after cooking or digestion. CONCLUSION: Thus, consumption of cooked fish, preferentially grilled seabass and steamed or baked white mullet are more advisable. This study highlights the importance to consider bioaccessibility and cooking in hazard characterization studies. © 2024 The Authors.

BACKGROUND: Bulgur, a whole wheat product, has attracted attention in the world in recent years because of its wide usage possibility in different meals. The basic ingredients in bulgur production are wheat and water. The influence of water composition on bulgur quality has not been investigated. Iron in water can cause discolouration in foods by oxidizing and reacting with phenolic compounds and also by hardening the structure of the foods. Therefore, in the present study, the effects of the iron content of water on the quality of bulgur were examined. RESULTS: The effect of the amount of iron in water on bulgur quality was carried out and examined using water containing iron at three different levels (0, 1 and 2 ppm). Using water containing 2 ppm iron in bulgur production caused a decrease in the L* value and an increase in the YI (i.e. yellowness index), thus negatively affecting the colour of the bulgur. In bulgur prepared with water containing 2 ppm iron, the antioxidant activity was also dramatically reduced. CONCLUSION: The iron content in the water used in bulgur production did not have a negative effect on bulgur quality up to 2 ppm. The protein, ash, phenolic and mineral amounts and textural characteristics of bulgur were not affected by the concentration of iron in the water. As a result, high iron concentration in cooking water negatively affects bulgur's colour and antioxidant activity. Therefore, it is recommended to use iron‐free water in bulgur production. © 2024 The Authors.

Background: People with intellectual disability have diverse needs and experience higher rates of diet‐related chronic disease such as type 2 diabetes compared to people without disability. However, they are infrequently included in development and implementation of interventions to address diet‐related chronic disease. The present study describes the process to plan, develop and refine the Food and Lifestyle Information Program (FLIP) culinary nutrition intervention for adults with mild‐to‐moderate intellectual disability. Methods: The project was initiated by a disability service provider and was guided by the Cook‐Ed™ model and inclusive research principles. Initially the disability service provider and academic research team members co‐designed pre‐program consultation and pilot studies, and draft program resources. Pre‐program consultation explored paid disability support worker (n = 10) perceptions of cooking and food skills, nutrition priorities and optimal program format, which guided further program drafting. Program resources and pilot study design were further developed and refined with co‐researchers with lived experience of intellectual disability who attended a pre‐pilot and then pilot study sessions as remunerated co‐facilitators. Results: Key characteristics of the FLIP intervention arising from pre‐program consultation included providing cooking task instruction in small steps, enabling participant choice in program activities, promoting an inclusive and social atmosphere, and providing paper‐based resources. Conclusions: FLIP intervention co‐design was enabled through ongoing input from the disability service provider and people with lived experience of intellectual disability. Evaluation of FLIP feasibility, acceptability and preliminary effectiveness to improve diet‐related health is underway. Highlights: An academic research team, disability service provider and people with lived experience of intellectual disability co‐designed a culinary nutrition intervention for adults with mild‐to‐moderate intellectual disabilityKey considerations for culinary nutrition programs for people with intellectual disability include providing small group practical instruction, paper‐based Easy Read recipes, providing choice and creating a social and inclusive atmosphere [ABSTRACT FROM AUTHOR]

Background: Optimal maternal nutrition is associated with better pregnancy and infant outcomes. Culinary nutrition programmes have potential to improve diet quality during pregnancy. Therefore, this research aimed to understand the experiences of cooking and the wants and needs of pregnant women regarding a cooking and food skills programme in the United Kingdom (UK) and Republic of Ireland (ROI). Methods: Online focus group discussions with pregnant women and those who had experienced a pregnancy in the UK or ROI were conducted between February and April 2022. Two researchers conducted a thematic analysis. Seven focus groups with ROI participants (n = 24) and six with UK participants (n = 28) were completed. Results: Five themes were generated. These were (1) cooking during pregnancy: barriers, motivators and solutions; (2) food safety, stress and guilt; (3) need for cooking and food skills programmes and desired content; (4) programme structure; (5) barriers and facilitators to programme participation. Overall, there was support for a programme focusing on broad food skills, including planning, food storage, using leftovers and to manage pregnancy‐specific physiological symptoms such as food aversions. Participants emphasised the importance of inclusivity for a diverse range of people and lifestyles for programme design and content. Conclusions: Current findings support the use of digital technologies for culinary nutrition interventions, potentially combined with in‐person sessions using a hybrid structure to enable the development of a support network. Highlights: Thirteen online focus group discussions were conducted across the UK and Ireland.Five themes were generated around cooking during pregnancy and the content and structure of a cooking and food skills programme.There was support for an inclusive cooking programme that included a wide range of food‐related skills.Participants believed the programme should be supported by the health services.There was support for the use of digital technologies, potentially combined with in‐person sessions using a hybrid structure.

A transition to clean fuels and technology for cooking is increasingly recognised as a cornerstone of sustainable development. However, sufficient, appropriate, affordable finance to support the transition is lacking. Grounded in primary data collection via expert interviews, this study's research objective was to critically assess development finance institutions' (DFIs) delivery of climate and development finance to address cooking poverty. Interview findings underscore DFIs' important role in the transition, including to create the ecosystem conditions conducive to sustained investment. However, as a group they are not demonstrating the risk appetite and financial solutions that clean cooking markets need. Nor are they operating with the agility and flexibility required for rapid scale-up. Consequently, DFIs are not optimally fulfilling their mandates to create additionality and mobilise private capital in these markets. Interviewees call for DFIs to reconsider their approach, and we rely on these findings to posit a theory of change for clean cooking finance. [ABSTRACT FROM AUTHOR]

Antinutrients in rice tend to impair nutrient bioavailability; hence, this study aimed to investigate the effects of cooking and simulated digestion on the antioxidant activity and phenolic content of white and brown rice, as well as the bioavailability of some minerals. The rice grains were cooked in a pressure cooker, using a 1:2 (w/v) rice-to-water ratio. The digestion of the cooked rice grains was then simulated using pepsin and pancreatin systems. The phenolic (total, free, and bound) and flavonoid content; antioxidant activity (DPPH, ABTS, and FRAP); phytic acid and tannin levels; and mineral HCl-extractability were all determined in the raw, cooked, and digested grains. The cooking process significantly lowered (p ≤ 0.05) the phenolic content of the white rice; however, the phenolic content increased significantly (p ≤ 0.05) when these cooked grains were digested. The phenolic content of brown rice decreased at a higher rate during cooking than that of white rice, and it recovered at a lower rate after digestion. The flavonoid content in both cooked and digested white and brown rice followed a similar trend with the phenolic content. This reduction in the phenolic and flavonoid content in both types of rice after cooking was associated with a large decrease in antioxidant activity, whereas, after digestion, it was associated with a considerable increase. After cooking, the levels of phytate and tannin in both types of rice decreased significantly (p ≤ 0.05), and this drop was even more pronounced in the digested grains. Although the mineral content in the cooked samples of white and brown rice decreased, it recovered after digestion; however, the mineral content remained lower than that of the raw samples. Despite this, there was also a rise in the bioavailability of the minerals in the cooked rice after digestion (p ≤ 0.05), which was considerably higher than the rise in the mineral content itself. The findings indicate that, while cooking rice decreases its phenolic content and antioxidant activity, it also lowers its antinutrient content. Additional benefits were also noted following the simulated digestion. [ABSTRACT FROM AUTHOR]

Chicken claw products with their unique texture are loved by consumers, and cooking is a key step to affect the taste of chicken claw consumption, through the moderate hydrolysis of proteins and a series of physicochemical changes, so that the chicken claw gets tender and presents a crispy taste, but the current research on the optimal cooking conditions for chicken claw is still relatively small. In the present work, combinations of time (11, 13, 15, 17, and 19 min) and temperature (82, 86, 90, 94, and 98°C) were applied to the cooking of chicken claws. The effects of different cooking conditions on the quality characteristics of chicken claws were investigated, with special emphasis on the cooking loss rate, color, texture properties, lipid oxidation, myofibrillar fragmentation index (MFI), and total sulfhydryl content. The results showed that the cooking loss rate, lipid oxidation, and MFI value of chicken claws gradually increased, and the total color difference (∆E), puncture force, shear force, and total sulfhydryl content gradually decreased with the increase of cooking temperature and cooking time. Overall, chicken claws cooked at 86, 90, and 94°C for 15 and 17 min had better texture and flavor. Cooking treatment had a significant effect on the quality characteristics of chicken claws. Overall, chicken claws cooked at 86, 90 and 94°C for 15 and 17 min had better texture and flavor. [ABSTRACT FROM AUTHOR]

Color changes in wheat and cooking water, which affect the quality of bulgur and wastewater, are important. Understanding the impacts of cooking water acidity, hardness, and iron content is significant for producing bright‐yellow colored bulgur and determining the possible negative effects of cooking water on the environment. Thereby, the gelatinization degree and color (L*, a*, b*, and yellowness index) of wheat cooked with waters at different pH (3, 5, 7, 9, and 11), hardness (soft, hard, and very hard), and iron content (0, 1, and 2 mg/L) were determined every 10 min of cooking. pH, Brix, conductivity, hardness, turbidity, and color of cooking waters were also determined and kinetically modeled. After cooking, it was revealed that cooking with water at pH 3 favored the color of cooked wheat, whereas pH 11 caused darkening. Nevertheless, as the wastewater pH of cooking waters with pH 3 and 11 may be harmful to the environment, it is recommended to use water in the range of pH 5–9 for bulgur production. Cooking with very hard water is also not recommended as it causes some adverse effects such as diminishing the gelatinization rate in wheat, increasing the cooking time, and negatively affecting the color.

Sorghum, a cereal grain rich in nutrients, is a major source of phenolic compounds that can be altered by different processes, thereby modulating their phenolic content and antioxidant properties. Previous studies have characterised phenolic compounds from pigmented and non-pigmented varieties. However, the impact of processing via the cooking and fermentation of these varieties remains unknown. Wholegrain flour samples of Liberty (WhiteLi1 and WhiteLi2), Bazley (RedBa1 and RedBa2), Buster (RedBu1 and RedBu2), Shawaya black (BlackSb), and Shawaya short black 1 (BlackSs) were cooked, fermented, or both then extracted using acidified acetone. The polyphenol profiles were analysed using a UHPLC-Online ABTS and QTOF LC-MS system. The results demonstrated that combining the fermentation and cooking of the BlackSs and BlackSb varieties led to a significant increase (p < 0.05) in total phenolic content (TPC) and antioxidant activities, as determined through DPPH, FRAP, and ABTS assays. The 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity of WhiteLi1, BlackSb, RedBu2, and BlackSs increased by 46%, 32%, 25%, and 10%, respectively, post fermentation and cooking. Conversely, fermentation only or cooking generally resulted in lower phenolic content and antioxidant levels than when samples were fully processed compared to raw. Notably, most of the detected antioxidant peaks (53 phenolic compounds) were only detected in fermented and cooked black and red pericarp varieties. The phenolic compounds with the highest antioxidant activities in pigmented sorghum included 3-aminobenzoic acid, 4-acetylburtyic acid, malic acid, caffeic acid, and luteolin derivative. Furthermore, the growing location of Bellata, NSW, showed more detectable phenolic compounds following processing compared to Croppa Creek, NSW. This study demonstrates that sorghum processing releases previously inaccessible polyphenols, making them available for human consumption and potentially providing added health-promoting properties.

Objective: The goal of this research was to uncover narratives around food access and consumption among Black women who attend HBCUs before and during the COVID-19 pandemic. Participants: Black women, ages 18–25. Methods: Focus groups were used to understand how participants defined healthy foods as well as barriers and facilitators of consumption. During the pandemic follow-up focus groups uncovered how COVID-19 impacted their access and consumption patterns. Results: Findings revealed that HCBU women faced similar and distinct concerns around food access prior to and during the pandemic. Students were limited by price, budgets, proximity to healthy foods, kitchen access, and cooking tools. However, proximity or transportation both before and during the COVID-19 pandemic encouraged students to access healthy foods. Conclusion: For students who are already at a societal disadvantage and attend a university located in a food desert, access to nutritious foods can be an exacerbated plight. [ABSTRACT FROM AUTHOR]

Despite the economic and cultural significance of Christmas in many nations, there has been relatively little geographical research on how it shapes people's socialities, spatialities, and subjectivities. In this paper, practice theory was used to reflect on the materials, meanings, and competencies associated with older people who host the celebration at home, and thematic analysis of qualitative interviews with 20 individuals aged 65+ explored participants' experiences of doing so. Findings reveal that homes' material forms affect older people's ability to host, while the 'stuff' of Christmas such as decorations, special foods, or gifts shape those homes as festive and welcoming places. Food sourcing and preparation were critical competencies for female participants, and shifting capacities to be a host influenced participants' sense of autonomy and identity. Regardless of the extent to which participants celebrated Christmas, the meanings of hosting centred on social connection, contribution, and shoring up family. Choosing not to host or being unable to contribute in expected ways at Christmas could signify failure, exclusion, or incapability as an older person, parent, or citizen. Examining these issues in the case study, based in Aotearoa/New Zealand, reveals the existence and effects of the social expectations, norms, and obligations that typify Christmas. More broadly, the study highlights the need for geographers to attend to the ways in which celebrations shape and are shaped by diverse practices, places, and peoples and are assembled, reproduced, and resisted.

Background: Cooking at home has been associated with better diet quality and, consequently, promoted by nutrition guidelines as necessary to avoid or reduce ultra-processed food consumption. Mothers are the main agents of culinary socialization, and the main cooks in the context of the home environment. Therefore, to effectively put dietary guidelines into practice it is desirable that public policies be informed by mothers' perceptions about home cooking. The aim of this systematic review is to gather evidence on mothers' perceptions about cooking-related matters at home. Methods: Qualitative studies or qualitative data from mixed methods studies which investigated mothers' perceptions about cooking at home will be included in this review. Databases to be searched for published studies include SCOPUS, Web of Science, PubMed, PsycINFO and SciELO. The search for unpublished studies (grey literature) will include Google Scholar, ProQuest Dissertations and Theses Global, as well as Brazilian Theses and Dissertations catalog, with no date or language restrictions. Titles and abstracts will be screened. The full texts of selected studies will be assessed in detail, and findings and illustrations will be extracted and aggregated. Any disagreements between the two independent reviewers that arise at each stage will be resolved through discussion, or by a third reviewer.

This study investigated the presence of nitrosamines, known carcinogens, in 1320 food samples from South Korea using LC-APCI-MS/MS analysis. Results showed nitrosamines were detected in 72% of samples, with processed foods exhibiting higher levels. Sesame oil, snow white rice cake, fried chicken wings, and fried squid were identified as having the highest nitrosamine content. Daily intake estimates revealed nitrosodiethylamine (NDEA), nitrosodibutylamine (NDBA), and nitrosopyrrolidine (NPYR) as major contributors to exposure. Risk assessment, based on BMDL10 values and MOE calculations, indicated low health risks overall, but certain food groups at the 95th percentile showed MOEs below the safety threshold, warranting attention. This underscores the need for ongoing monitoring and regulation of nitrosamine levels in food products to protect public health, particularly in regions with high consumption of processed foods like South Korea. Further research and regulatory measures are crucial to minimize nitrosamine exposure and mitigate associated health risks. [ABSTRACT FROM AUTHOR]

Background: In the intricate tapestry of food security, wild food species stand as pillars, nourishing millions in low-income communities, and reflecting the resilience and adaptability of human societies. Their significance extends beyond mere sustenance, intertwining with cultural traditions and local knowledge systems, underscoring the importance of preserving biodiversity and traditional practices for sustainable livelihoods. Methods: The present study, conducted between February 2022 and August 2023 along the Line of Control in India's Kashmir Valley, employed a rigorous data collection encompassing semi-structured interviews, focus group discussions, and specific field observations facilitated through a snowball sampling technique. Results and discussion: The comprehensive inventory includes 108 edible plant and fungal species from 48 taxonomic families, with Rosaceae (N = 11) standing out. Young and soft leaves (N = 60) are an important component of various culinary preparations, with vegetables (N = 65) being the main use, followed by fruits (N = 19). This use is seasonal, with collection peaks in March–April and June–August (N = 12). The study also highlights the importance of use value (UV), with Portulaca oleracea standing out as the plant taxon (UV = 0.61), while Asyneuma thomsoni has the lowest use value (UV = 0.15). Many species such as Senecio chrysanthemoides, Asperugo procumbens, Asyneuma thomsoni, and Potentilla nepalensis were classified as new for gastronomic use. Furthermore, the study underlines the great cultural importance of mushrooms such as Morchella esculenta and Geopora arenicola in influencing social hierarchies within the community. However, the transmission of traditional knowledge across generations is declining in the region. At the same time, the conservation of endangered plant species on the IUCN Red List, such as Trillium govanianum, Taxus wallichiana, Saussurea costus, and Podophyllum hexandrum, requires immediate attention. Conclusion: Conservation measures should be prioritized, and proactive remedial action is needed. Further research into the nutritional value of these edible species could pave the way for their commercial cultivation, which would mean potential economic growth for local communities, make an important contribution to food security in the area under study, and contribute to scientific progress.

Cooking, a quintessential creative pursuit, holds profound significance for individuals, communities, and civilizations. Food and cooking transcend mere sensory pleasure to influence nutrition and public health outcomes. Inextricably linked to culinary and cultural heritage, food systems play a pivotal role in sustainability and the survival of life on our planet. Computational Gastronomy is a novel approach for investigating food through a data-driven paradigm. It offers a systematic, rule-based understanding of culinary arts by scrutinizing recipes for taste, nutritional value, health implications, and environmental sustainability. Probing the art of cooking through the lens of computation will open up a new realm of possibilities for culinary creativity. Amidst the ongoing quest for imitating creativity through artificial intelligence, an interesting question would be, 'Can a machine think like a Chef?' Capturing the experience and creativity of a chef in an AI algorithm presents an exciting opportunity for generating a galaxy of hitherto unseen recipes with desirable culinary, flavor, nutrition, health, and carbon footprint profiles.

In this study, the flavor characteristics and physicochemical properties of salted egg yolk (SEY) under different cooking methods (steaming/baking/microwaving) were investigated. The microwave-treated SEY exhibited the highest levels of salt content, cooking loss, lightness, and b* value, as well as the highest content of flavor amino acids. A total of 31, 27, and 29 volatile compounds were detected after steaming, baking, and microwave treatments, respectively, covering 10 chemical families. The partial least squares discriminant analysis confirmed that 21 compounds, including octanol, pyrazine, 2-pentyl-furan, and 1-octen-3-ol, were the key volatile compounds affecting the classification of SEY aroma. The electronic nose revealed a sharp distinction in the overall flavor profile of SEY with varying heat treatments. However, no dramatic differences were observed in terms of fatty acid composition. Microwave treatment was identified as presenting a promising approach for enhancing the aroma profile of SEY. These findings contribute novel insights into flavor evaluation and the development of egg products as ingredients for thermal processing. [ABSTRACT FROM AUTHOR]

It is reasonable to state that gastronomic tourism is an efficient tool that has the potential to refresh Thailand's macroeconomic viability. With the aim of becoming a hub of tourism in Southeast Asia, Thailand's tourism industry must urgently address and sustainably integrate gastronomic activities to navigate the troubled situation caused by its decline after the COVID-19 pandemic. This has led the authors to conduct a deep study on a regional input–output (I-O) table analysis for Thailand's tourism system, specifically focusing on gastronomic activities and tourism industries. The tourism I-O data used in this study come from the official source provided by the Thailand Ministry of Tourism and Sport. Empirically, the results of the dynamic regional I-O model predict that Bangkok and its surrounding areas are the heart of gastronomic tourism development, driving income into Thailand's economy. The eastern region stands as the second-largest area of gastronomy tourism, generating a positive impact on Thailand's economy. On the other hand, the Northeast of Thailand receives less income from gastronomy tourism despite being the largest area in the country. Ultimately, there should be a greater emphasis on gastronomy tourism policies in order to fully maximize their potential for tourism development, stimulating every part of Thailand during the economic depression caused by COVID-19. Moreover, gastronomy tourism has the potential to play an important role in driving economic growth through the combination of cuisine and tourism development. [ABSTRACT FROM AUTHOR]

Domestic cooking is changing the world over. Kitchen technologies and the smartphone transform the way we cook and whom we cook with. Coupled with urbanisation and the shrinking of households, cooking seems to be an increasingly solitary practice. At the same time, these processes did not change who cooks; across the globe it is mostly women who prepare the daily meal for their families. Yet, rather than treating domestic cooking solely as a gender relations issue, this article presents ethnographic research with low-income domestic cooks in Marrakech, Morocco, to argue that unequal generational relations are also important drivers of change in family life. Paradoxically, rather than cook alone or simplify meals, kitchen appliances and social media were employed to continue preparing elaborate family meals. Through a thick description of the preparation of a spread called amlou and of pizza, this article explores why domestic cooking remains centralto idealised notions of womanhood and family life in Marrakech and beyond. It introduces the concept of culinary connectivity to understand how new technologies were employed ininter-generational negotiations of cooking knowledge and power. Moreover, while the crafting of culinary connectivity enables young generations of low-income womento emancipate themselves from age-based power in the home, these practices also enmesh them in new relations of dependence on money and the market. By making cooking central to understanding the (re)production of everyday family life in the context of poverty, this article contributes to cross-cultural studies of food and to regional debates about the family.

Background and Objectives Approximately 60% of people living with dementia at home are unable to routinely participate in mealtime activities (e.g. eating, safe food preparation), warranting assistance to ensure people with dementia meet their health and nutritional needs. The purpose of this study was to characterize these barriers to mealtime participation and identify potential caregiver-led strategies to enhance mealtime activities. Research Design and Methods We used a qualitative descriptive approach and obtained semistructured interview data from (a) allied health professionals and (b) community-based nutrition program providers who frequently serve people with dementia. Interview data were examined by means of directed content analysis and framework methodology until data saturation was reached. Codes from our analysis were categorized according to constructs drawn from the Socio-Ecological Model for Developing and Implementing Comprehensive Dementia Care. Results Data were obtained from 20 participants who attributed common mealtime participation barriers to: impairments in functional status, cognitive status deficits, a lack of caregiver knowledge and skills, and unsafe living conditions. Caregiver-led strategies to overcome these barriers included: reducing auditory and visual distractions, providing written cues to perform mealtime activities, eliminating clutter and fall risk hazards, and leveraging community-based nutrition program providers (e.g. home-delivered meal providers). Discussion and Implications People with dementia face several eating and mealtime participation obstacles. Caregiver-led strategies implemented by family, friends, or community-based nutrition program providers may enhance mealtime activities at home. Findings point to opportunities to develop decision-making tools and resources for caregivers to optimize the health and nutrition of people with dementia. [ABSTRACT FROM AUTHOR]

The prison's culinary sphere is a vibrant social arena where the institution's power structure and dynamics are exposed, enforced, negotiated, and restructured. In Israel, the practice of cooking inside the prison cells is not officially permitted (or forbidden) but is generally tolerated by the prison staff. People in Israeli prisons form ethnic-based in-cell cooking groups, allot resources, and invest skills, time, and effort in cooking their own meals. In this article, we explore the meanings attributed to in-cell group cooking by people incarcerated in Israeli prisons. We applied interpretive phenomenological analysis to interviews with 18 people in prison. Three themes emerged from the participants' narratives: (1) in-cell group cooking as an ambiguous practice, (2) the cooking group as a hub for conflict resolution and maintenance of community life, and (3) the cooking group as an opportunity to preserve some aspects of out-of-prison identity and freedom. In the discussion, we introduce the term "culinary redemption" and argue that prison food is a powerful marker of "being inside," while the substantial efforts invested by people in prison to improve their diet and create alternatives aim at changing their self-perception from inmates to free persons, at least to a certain extent.

Transitioning to clean cooking fuels is not only part of achieving SDG7 but also makes a significant contribution to mitigating climate change by reducing carbon emissions. Research projects and pilots across a number of countries in Africa and South Asia have been exploring the suitability and energy performance of different cooking appliances and fuels. The paper presents the first statistical analysis across these multiple datasets to determine the range of energy required to cook dishes using different technologies and fuels. The paper draws out distinctions between African and Asian dishes, notably the impact of energy-intensive dishes prepared mostly in Africa. The paper demonstrates that the standard efficiency-based approaches to comparing the performance of stoves are not appropriate to modern electric cooking devices, so a novel alternative approach based on specific energy consumption and termed energy ratios is developed. Charcoal stoves are shown to use 15 times as much energy as electric pressure cookers (EPCs) to cook African dishes, and a detailed review of how the EPC works explains why this should be. Energy ratios provide a basis for estimating carbon emission reductions associated with transitioning to modern cooking fuels and also for estimating household cooking costs. Fuel and electricity prices from studies show that the cost of cooking with an EPC can be only 20% of the cost of cooking with charcoal, which highlights the potential for modern, energy-efficient electric cooking devices to defy the conventional wisdom of the energy ladder.

This study explored whether household and outdoor air pollution is associated with a greater risk for metabolic syndrome (MetS) among women. In all 11,860 women who cooked with clean energy were included in the analysis. Cooking frequency, range hood use during cooking, passive smoking exposure, and solid fuel use for heating were used to represent household air pollution. The 2-year average concentration of PM2.5, and face mask usage were used to reflect outdoor air pollution exposure. An index of air pollution exposure was also constructed. Multivariable logistic regression models were used to estimate the association between air pollution and risk for MetS, and a positive correlation was found. Our results indicated that household cooking used clean energy and exposure to a high level of outdoor PM2.5 without face mask usage may contribute to an increased risk for MetS among women.

Following a traumatic brain injury (TBI), meal preparation may become challenging as it involves multiple cognitive abilities and sub-tasks. To support this population, the Cognitive Orthosis for coOKing (COOK) was developed in partnership with an alternative residential resource for people with severe TBI. However, little is known about the usability of this technology to support people with TBI living in their own homes. A usability study was conducted using a mixed-methods single-case design with a 35-year-old man with severe TBI living alone at home. The number of assistances provided, time taken and the percentage of unnecessary actions during a meal preparation task were documented nine times to explore the usability of COOK. Interviews were also conducted with the participant to document his satisfaction with COOK. Potential benefits were explored via the number of meals prepared per week. The usability of COOK was shown to be promising as the technology helped the participant prepare complex meals, while also reducing the number of assistances needed and the percentage of unnecessary actions. However, several technical issues and contextual factors influenced the efficiency and the participant's satisfaction with COOK. Despite improving his self-confidence, COOK did not help the participant prepare more meals over time. This study showed that COOK was easy to use and promising, despite technical and configuration issues. Results suggest the importance of further technological developments to improve COOK's usability and fit with the needs of people with TBI living in their own homes. Cognitive Orthosis for coOKing (COOK) is a promising technology to support people with TBI when preparing meals within their homes, though usability issues need to be corrected. Factors such as current meal-preparation related habits, expectations and availability of technical support were found to influence the usability of COOK. Various questions to consider in future studies involving an assistive technology for cognition to support meal preparation were identified. [ABSTRACT FROM AUTHOR]

Rural residency is an independent risk factor for being overweight, but little is known about why this is so. The purpose of our study was to gain insight into what Norwegian rural children say about a rural diet in comparison to an urban one. Child‐friendly methods were used. We found a discrepancy between what the children said they eat – traditional, 'healthy' foods, and what they ate – largely ultra‐processed foods. We explored this by using the frameworks of imagined foodways and biopedagogies. Their imagined foodways were rooted in notions of 'traditional food', connected to surrounding nature and a history of farming and hunting. Urban people were perceived as eating an inferior diet of very unhealthy and ultra‐processed foods of which they do not know the origin of. As a result, the children rejected specific health‐ and nutrition recommendations that were incompatible with their notions of traditional foods, leading to a more calorie dense diet than their urban counterparts. Our research adds to knowledge on what role a rural diet can play on the prevalence of overweight in rural areas, and how biopedagogies can be recontextualized within different cultural fields.

The purpose of this study was to develop a restaurant authenticity scale (RAS), containing multiple restaurant attributes and authenticity conceptualizations. A four-step approach was used to develop this scale. Ultimately, the RAS contained 20 items and three dimensions: authenticity of ambiance, authenticity of cuisine, and authenticity of people. Findings from the current study show that the authenticity of cuisine dimension explained the greatest amount of variance of restaurant authenticity. With regard to theory, the current study has determined which items, authenticity conceptualizations, and dimensions should be included in the RAS. The current study offers guidance to restaurant practitioners by calling attention to key restaurant attributes which are critical to guests' perceptions of restaurant authenticity.

In this study, the effects of the cooking methods (frying, stir-frying, air-frying, boiling, steaming, baking and sous-vide, and microwaving) on total phenolic content (TPC) and sensory profile of cauliflower have been investigated. Higher cooking temperatures have resulted in higher TPC values, which can be attributed to the generation of new phenolics by the Maillard reaction and cleavage of bound phenolics. The highest TPC and bitterness were obtained when steaming and baking (180°C for 20 min) were applied. While the boiling procedure results in low bitterness and sweetness due to the loss of related compounds in boiling water, the taste of cooked cauliflower was higher when steamed (12 min) and stir-fried (4.5 min). Overall acceptability of the boiled, steamed, and fried samples was higher than in baked and sous-vide treated samples. Steaming was determined as the best technique regarding TPC content and sensory properties. [ABSTRACT FROM AUTHOR]
