Background: Gari and eba, forms of cassava semolina, are mainly consumed in Nigeria and other West African countries. This study aimed to define the critical quality traits of gari and eba, to measure their heritability, to define medium and high throughput instrumental methods for use by breeders, and to link the traits with consumer preferences. The definition of a food product's profiles, including its biophysical, sensory, and textural qualities, and the identification of the characteristics that determine its acceptability, are important if new genotypes are to be adopted successfully. Results: Eighty cassava genotypes and varieties (three different sets) from the International Institute of Tropical Agriculture (IITA) research farm were used for the study. Participatory processing and consumer testing data on different types of gari and eba products were integrated to prioritize the traits preferred by processors and consumers. The color, sensory, and instrumental textural properties of these products were determined using standard analytical methods, and standard operating protocols (SOPs) developed by the RTBfoods project (Breeding Roots, Tubers, and Banana Products for End-user Preferences, https://rtbfoods.cirad.fr). There were significant (P

Background Understanding end-users’ preferred breeding traits and plant management practices is fundamental in defining sound breeding objectives and implementing a successful plant improvement programme. Since such knowledge is lacking for Synsepalum dulcificum, a worldwide promising orphan fruit tree species, we assessed the interrelationships among socio-demography, ecology, management practices, diversity and ranking of desired breeding traits by end-users of the species (farmers, final consumers and processing companies) in West Africa. Methods Semi-structured interviews, field-visits and focus groups were combined to interview a total of 300 farmers and final consumers belonging to six sociolinguistic groups sampled from three ecological zones of Benin and Ghana. One processing company in Ghana was also involved. Data collected included socio-demographic characteristics; crop management systems and practices; and preferences of farmers, final consumers and processing companies and ranking of breeding traits. Data were analysed using descriptive statistics, independence, and non-parametric tests, generalized linear models, multi-group similarity index and Kendall’s concordance coefficient. Results Men (86.33% of respondents) were the main holders of S. dulcificum in the study area. The three most frequent management practices observed in the species included weeding, fertilization and pruning, which were applied by 75.66%, 27.33% and 16.66% of respondents, respectively. The management intensity index varied significantly across ecological zones, sociolinguistic groups, and instruction level (p < 0.001) but was not affected by gender (p > 0.05). General multigroup similarity indices ($$ {\mathrm{C}}_{\mathrm{S}}^{\mathrm{T}} $$ C S T ) for farmer-desired traits, on one hand, and final consumer-desired traits, on the other hand, were high across ecological zones ($$ {\mathrm{C}}_{\mathrm{S}}^{\mathrm{T}} $$ C S T ≥ 0.84) and sociolinguistic groups ($$ {\mathrm{C}}_{\mathrm{S}}^{\mathrm{T}} $$ C S T > 0.83). Nevertheless, respondents from the Guineo-Congolian (Benin) and the Deciduous forest (Ghana) zones expressed higher agreement in the ranking of desired breeding traits. Preference for breeding traits was 60% similar among farmers, final consumers, and processors. The key breeding traits desired by these end-users included in descending order of importance big fruit size, early fruiting, high fruit yielding (for farmers); big fruit size, high fruit miraculin content, fruit freshness (for final consumers); and high fruit miraculin content, big fruit size, high fruit edible ratio (for processing companies). Conclusion This study revealed stronger variations in current management practices across ecological zones than across sociolinguistic groups. A high similarity was shown in end-users’ preferences for breeding traits across the study area. Top key traits to consider in breeding varieties of S. dulcificum to meet various end-users’ expectations in West Africa include fruit size and fruit miraculin content. These results constitute a strong signal for a region-wide promotion of the resource.

International audience; This study focuses on the perception of ethnic foods by European consumers. The aim of this work is to enrich the literature on the analysis of consumer perception of ethnic foods by focusing on the socio-demographic characteristics of consumers, the possible role played by product attributes, psychographic characteristics, and willingness to pay for these products, specifically date fruits. We surveyed a representative sample of 1123 Italian and French consumers. Using an ordered logit model, we found that, as for any other product, geographical indication, region of production, organic character, and fair trade are attributes that individuals consider in their purchase decisions for ethnic foods. Similarly, country of origin is a source of quality for ethnic foods such as dates. The results reveal that women, more educated individuals, and Generation Z (younger individuals) have a higher willingness to pay for organic, fair trade, and GI-labeled ethnic foods. Finally, this willingness to pay is driven more by product knowledge than by cognitive closeness to the ethnic food.

BackgroundTo limit the spread of COVID-19, a strict lockdown was imposed in France between March and May 2020. Mobility limitations and closure of non-essential public places (restaurants, open-air markets, etc.) affected peoples' food environment (FE) and thus their food purchasing practices (FPPs). This study aimed to explore changes in FPPs of French households during lockdown and associations with individual and environmental factors.MethodsIn April of 2020 households from the Mont'Panier cross-sectional study (n = 306), a quota sampling survey conducted in the south of France, were asked to complete an online questionnaire about their FPPs during lockdown and related factors, including perceived FE (distance to closest general food store, perception of increased food prices, etc.). Objective FE (presence, number, proximity, and density of food outlets) was assessed around participant's home using a geographical information system. Multiple correspondence analysis based on changes in frequency of use and quantity of food purchased by food outlet, followed by a hierarchical cluster analysis, resulted in the identification of clusters. Logistic regression models were performed to assess associations between identified clusters and household's sociodemographic characteristics, perceived, and objective FE.ResultsFive clusters were identified. Cluster “Supermarket” (38% of the total sample), in which households reduced frequency of trips, but increased quantity bought in supermarkets during lockdown, was associated with lower incomes and the perception of increased food prices. Cluster “E-supermarket” (12%), in which households increased online food shopping with pickup at supermarket, was associated with higher incomes. Cluster “Diversified” (22%), made up of households who reduced frequency of trips to diverse food outlet types, was associated with the perception of increased food prices. Cluster “Organic Food Store” (20%), in which households did not change frequency of trips, nor quantity purchased in organic food stores, was associated with being older (35–50 y vs. ConclusionThis study highlighted diverse changes in FPPs during lockdown and overall more significant associations with perceived than with objective FE indicators.

APROVADO CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior The purpose of this research is to describe the factors that influence consumer purchase intent in omnichannel retailers. We began the study with a literature review based on omnichannel strategy in relation to omnichannel consumer behavior; the emergence of connected and mobile devices, and the different types of channels that evolve up to the omnichannel strategy. Retailers are developing strategies to account for the effect of smartphones that are eliminating the distinction between channels and changing consumer behavior. To conduct this research, we adopted a descriptive quantitative study; first, we designed an online survey focused on omnichannel retail customers in one region of Brazil, we developed a questionnaire based on the literature review regarding consumer purchase intention. As we focus on omnichannel retailers and consumers' experiences with multiple channels and new technology, we started from the questions presented by Juaneda-Ayensa, Mosquera, and Murillo (2016) and Santos (2014) and then developed the questionnaire; we conducted a pretest with three participants after the approval of the ethics committee to check for possible misunderstanding or confusion with the instrument. Based on the suggestions received, the wording and format of four questions were modified. We used IBM SPSS Statistics 26 to perform the exploratory factor analysis. Subsequently, we developed a latent variable analysis based on the partial least squares (PLS) technique. We had a total of 359 respondents during the data collection period (from October 18, 2021 to November 7, 2021). The respondents were asked about their behavior during their last purchase in the 12 months prior to data collection. The results of this research show that effort expectancy and performance expectancy are important factors to explain the attitude and purchase intention, with a positive effect on the behavioral intention, and the main determinants of purchase intention in an omnichannel context and the profile of consumers in the regions of Triângulo Mineiro and Alto Paranaíba, based on their purchase experiences with a company recognized as omnichannel and active in the studied region. Our study contributes to a better understanding of the purchase intentions of omnichannel consumers in their buying process and the factors that influence them and the specificity of each channel and each touch point in the composition of the customer's consumption experience. Esta pesquisa tem como objetivo descrever os fatores que influenciam a intenção de compra do consumidor em varejistas omnichannel. Iniciamos o estudo com uma revisão bibliográfica baseada em uma estratégia omnichannel em relação ao comportamento omnichannel do consumidor, o surgimento de dispositivos conectados e móveis, e os diferentes tipos de canais que desenvolvem a estratégia omnichannel. Os varejistas estão desenvolvendo estratégias para lidar com o efeito dos smartphones que estão eliminando a distinção entre canais e mudando o comportamento do consumidor. Para conduzir esta pesquisa, adotamos um estudo quantitativo descritivo; primeiro, projetamos uma pesquisa online focada em clientes de varejo omnichannel em uma região do Brasil, desenvolvemos um questionário baseado na revisão da literatura sobre a intenção de compra do consumidor. Ao nos concentrarmos nas experiências de varejistas omnichannel e consumidores com múltiplos canais e novas tecnologias, partimos das perguntas apresentadas por Juaneda-Ayensa, Mosquera e Murillo (2016) e Santos (2014), e propomos um instrumento para coleta de dados; realizamos um pré-teste com três participantes após a aprovação do comitê de ética para verificar possíveis mal-entendidos ou confusão com o instrumento. Com base nas sugestões recebidas, a redação e o formato de quatro perguntas foram alterados. Utilizamos o IBM SPSS Statistics 26 para realizar a análise do fator exploratório. Posteriormente, realizamos uma análise variável latente baseada na técnica dos mínimos quadrados parciais (PLS). Tivemos um total de 359 respondentes do questionário de pesquisa durante o período de coleta de dados de 18 de outubro de 2021 a 7 de novembro de 2021. Os respondentes foram então questionados sobre seu comportamento durante sua última compra nos 12 meses anteriores à coleta de dados. Os resultados desta pesquisa mostram que a expectativa de esforço e a expectativa de desempenho são fatores importantes para explicar a atitude e a intenção de compra, com um efeito positivo sobre a intenção de comportamento, e os principais determinantes da intenção de compra em um contexto omnichannel e o perfil dos consumidores nas regiões do Triângulo Mineiro e Alto Paranaíba, com base em suas experiências de compra com uma empresa reconhecida como omnichannel e ativa na região estudada. Nosso estudo contribui para uma melhor compreensão das intenções de compra dos consumidores omnichannel em seu processo de compra e os fatores que os influenciam e a especificidade de cada canal e ponto de contato na composição da experiência de consumo do cliente. Cette recherche vise à décrire les facteurs qui influencent l'intention d'achat des consommateurs chez les détaillants omnicanaux. Nous avons commencé l'étude par une revue de littérature basée sur la stratégie omnicanale en relation avec le comportement du consommateur omnicanal. L'émergence des appareils connectés et mobiles, et les différents types de canaux que font évoluer la stratégie omnicanale. Les détaillants développent des stratégies pour prendre en compte l'effet des smartphones qui éliminent la distinction entre les canaux et modifient le comportement des consommateurs. Pour mener cette recherche, nous avons adopté une étude quantitative descriptive ; tout d'abord, nous avons conçu une enquête en ligne axée sur les clients de la vente au détail omnicanale dans une région du Brésil, nous avons développé un questionnaire basé sur la revue de la littérature concernant l'intention d'achat des consommateurs. Comme nous nous concentrons sur les détaillants omnicanaux et les expériences des consommateurs avec les canaux multiples et la nouvelle technologie, nous avons commencé à partir des questions présentées par Juaneda-Ayensa, Mosquera et Murillo (2016) et Santos (2014) ; nous avons effectué un pré-test avec trois participants après l'approbation du comité d'éthique pour vérifier les éventuels malentendus ou la confusion avec l'instrument. À partir des suggestions reçues, la formulation et le format de quatre questions ont été modifiés : au lieu d'énumérer les options, le répondant indique l'option principale par ordre de préférence, les répondants choisissent l'option principale ; Nous avons utilisé IBM SPSS Statistics 26 pour effectuer l'analyse factorielle exploratoire. Par la suite, nous avons entrepris une analyse des variables latentes basée sur la technique des moindres carrés partiels (PLS). Nous avons eu au total 359 répondants disponible à avoir répondu au questionnaire de recherche durant la collecte de données qui se fait entre 18 octobre 2021 a 7 novembre 2021. Ensuite, les répondants ont été interrogés sur leur comportement lors de leur dernier achat au cours des 12 mois précédant la collecte des données. Les résultats de cette recherche montrent que l'espérance d'effort et l'espérance de performance sont des facteurs importants pour expliquer l'attitude et l'intention d'achat, avec un effet positif sur l'intention comportementale, et les principaux déterminants de l'intention d'achat dans un contexte omnicanal et le profil des consommateurs des régions de Triângulo Mineiro et Alto Paranaíba, sur la base de leurs expériences d'achat auprès d'une entreprise reconnue comme omnicanale et active dans la région étudiée. Notre étude contribue à une meilleure compréhension des intentions d'achat des consommateurs omnicanaux dans leur processus d'achat et des facteurs qui les influencent et la spécificité de chaque canal et de chaque point de contact dans la composition de l'expérience de consommation du client.

This study was designed and carried out to ascertain the situation and perceptions of end users of cassava flash drying equipment in Nigeria with the aim of giving suggestions to policies and approaches for improved technology. Forty-one processing firms were selected and interviewed. Descriptive analyses were used and a logistic regression model was estimated. The results revealed that 49% of the firms stopped using their flash dryers due to the low demand for high-quality cassava flour (HQCF) resulting from the high cost of processing occasioned by an inefficient heat-generating component. The estimated model provides evidence that cost effectiveness (p < 0.05) and energy cost (p < 0.10) are the two major determinants of the continuous usage of flash dryers in the study area. Forty-one percent of the firms indicated willingness to pay for any technical adjustment of their flash dryers, supposing such adjustment would improve on drying and the energy efficiency of the equipment up to 40%. The study recommends that machine fabricators in Nigeria and other African countries should be trained on the production of energy- and cost-efficient small-scale flash dryers. Again, the design and commercialization of flash dryers that can be mounted on mobile trucks for farm-gate processing should be encouraged to facilitate farm-gate processing, thereby reducing postharvest losses resulting from transporting perishable and bulky roots over a long distance.

International audience; In France, the market on which this chapter focuses, the sales outlets for packaging-free products are multiplying, the range of products sold without packaging is growing, producers are demonstrating a great capacity for innovation and supply chains are being organized. Packaging has become a commercial interface that, like the brand and its advertising, acts as an intermediary between the consumer and the product. The products are acquired for their content, but also because of the container and its brand. The growth of the power of packaging-free consumption has occured in tandem with increasing media coverage of the environmental and health impact of packaging, particularly plastics. Packaging-free consumption is currently primarily the preserve of organic stores, but large and medium-sized stores, which are increasingly interested in the market, account for 40% of sales. Faced with packaging-free products that can be considered new Objets comestibles non identifies , consumers must relearn the rules of consumption.

Prioritizing sensory attributes and consumer evaluation early in breeding trials to screen for end-user preferred traits could improve adoption rates of released genotypes. In this study, a lexicon and protocol for descriptive sensory analysis (DSA) was established for sweetpotato and used to validate an instrumental texture method for which critical values for consumer preference were set. The study comprised several phases: lexicon development during a 4-day workshop; 3-day intensive panel training; follow-up virtual training, evaluation of 12 advanced genotypes and 101 additional samples from two trials in 2021 by DSA and instrumental texture analysis using TPA double compression; and DSA, instrumental texture analysis and consumer acceptability tests on 7 genotypes in on-farm trials. The established sweetpotato lexicon comprising 27 sensory attributes enabled characterization and differentiation of genotypes by sensory profiles. Significant correlation was found between sensory firmness by hand and mouth with TPA peak positive force (r = 0.695 and r = 0.648, respectively) and positive area (r = 0.748, r = 0.715, respectively). D20, NAROSPOT 1, NASPOT 8, and Umbrella were the most liked genotypes in on-farm trials (overall liking = 7). An average peak positive force of 3700 gf was proposed as a minimum texture value for screening sweetpotato genotypes, since it corresponded with at least 46 % of consumers perceiving sweetpotatoes as just-about-right in firmness and a minimum overall liking of 6 on average. Combining DSA with instrumental texture analysis facilitates efficient screening of genotypes in sweetpotato breeding programs.

International audience

International audience; An economic experiment was conducted in France in 2020 to evaluate consumer attitudes toward two ham products associated with different colorectal cancer risks. We focused specifically on comparing a conventional ham and a new hypothetical antioxidant-enriched ham with a reduced risk of provoking colorectal cancer. Study participants were given descriptions of the two hams before carrying out successive rounds of willingness-to-pay (WTP) assessments. The results show that WTP was higher for the antioxidant-enriched ham than for the conventional ham. WTP estimates were also impacted by providing additional information about the reduction in colorectal cancer risk associated with the antioxidant-enriched ham. Based on the participants’ WTP, we came up with ex ante estimates for the social impacts of introducing the antioxidant-enriched ham onto the market, and we suggest that it would be socially optimal to promote the product. Competition arising from pre-existing product labelling and marketing assertions could greatly limit the market potential of antioxidant-enriched ham, which suggests that alternative approaches may be necessary, such as regulations mandating antioxidant enrichment. These results also concern all countries with high levels of meat consumption.; Une expérimentation économique a été menée en France en 2020 pour évaluer les attitudes des consommateurs par rapport à deux jambons associés à différents risques de cancer colorectal. Nous nous sommes concentrés spécifiquement sur la comparaison d'un jambon conventionnel et d'un nouveau jambon hypothétique enrichi en antioxydants, avec un risque réduit de provoquer un cancer colorectal. Les participants à l'étude ont reçu une description des deux jambons avant de procéder à des séries successives d'évaluations des consentements à payer (CAP). Les résultats montrent que le CAP moyen est plus élevé pour le jambon enrichi en antioxydants que pour le jambon conventionnel. Les CAP ont également été impactés par des informations supplémentaires sur la réduction du risque de cancer colorectal associé au jambon enrichi en antioxydants. Sur la base des CAP des participants, nous avons établi des estimations ex ante des impacts économiques liés à l’introduction du jambon enrichi en antioxydants sur le marché, et nous suggérons qu’il serait socialement optimal de promouvoir ce nouveau produit. La concurrence provenant des étiquetages et des labels préexistants pourrait considérablement limiter le potentiel de vente de ce jambon enrichi en antioxydants. Cela suggère des approches alternatives comme l’enrichissement obligatoire en antioxydants des jambons. Ces résultats concernent également tous les pays à forte consommation de viande.

Consumers prefer cassava roots that cook quickly during boiling. Current methods to evaluate cooking time (CT) are slow and labor‐intensive. This article describes improved protocols for assessing CT in roots. We evaluated CT in 36 genotypes monthly at 8‐11 months after planting. CT showed differences for plant age at harvest and among genotypes. During boiling, roots absorbed water (WAB) and thus reduced their relative density (DEN). We classified three groups of genotypes with increasing CT (≤25min, 25 to 40min, >40min), associated with decreasing WAB, respectively 15.3±3.1, 10.7±1.7 and 4.9±3.8% of initial root weight. A similar trend was observed for changes in DEN (46.3±9.8, 54.5±11.1 and 75.9±6.9% of initial DEN, respectively). The highest correlations between WAB and DEN with CT (r2 > 0.6) were found at 30‐min boiling. These alternative protocols facilitate screening large numbers of cassava genotypes for CT.

Breeding programmes for root, tuber and banana (RTB) crops have traditionally considered consumer demand for quality characteristics as low priority against other considerations such as yield and disease resistance. This has contributed to low levels of adoption of new varieties and its potential benefits. To address these challenges, an interdisciplinary five-step methodology was developed to identify demand for quality characteristics among diverse user groups along the food chain. The methodology includes an evidence review, consultations with key informants and rural communities, processing diagnosis with experienced processors and consumer testing in urban and rural areas. Quality characteristics are then prioritised into a Food Product Profile by user group to inform further work of biochemists and breeders in developing improved selection tools. This initiative presents a new basis to understand consumer preferences for RTB crops. The methodology is currently being applied in projects in sub-Saharan Africa and is applicable globally.

“Consumers have their say: assessing preferred quality traits of roots, tubers and cooking bananas, and implications for breeding” special issue, brings together new knowledge about quality traits required for roots, tubers and bananas (RTB) varieties to successfully meet diverse user preferences and expectations, along the variety development and RTB value chains (production, processing, marketing, food preparation, consumption). Key RTB crops in sub-Saharan Africa are cassava, yams, sweetpotatoes, potatoes and bananas/plantains. They are mainly consumed directly as boiled pieces or pounded in the form of smooth, not sticky, and stretchable dough. They are also stewed, steamed or fried. Cassava, the most widely grown RTB, is generally boiled, stewed or steamed in Eastern and Southern Africa, and in West and Central Africa is usually processed directly into derivative products, e.g. whole root fermentation through retting or heap fermentation; fermentation/dewatering of the mash. Biophysical and social knowledge presented in this issue help elaborate goals for both the processing unit operations (food scientist control) and variety traits (breeder control).

International audience; Food loss and waste (FLW) in developing countries is often high at postharvest stages due to technical and infrastructural constraints, while supermarket expansion has induced organizational, institutional and technological changes in the agrifood supply chains. Here we assess the volume of FLW along a food supply chain (FSC) and analyze the roles that supermarket and non-supermarket channels play in dealing with FLW. The study is based on primary data collected along a tomato chain-from production to retailing-in Cali (Colombia). The results revealed relatively low FLW due to: 1) the diversity of consumer preferences, 2) the reduced harvest-tosale time, 3) the marketing strategies adopted to sell downgraded and damaged products, and 4) the overlap and complementarity between supermarket and non-supermarket channels. The study highlights the importance of preserving the diversity of these marketing channels to avoid unsold food products, meet the range of consumers' needs, while providing greater marketing opportunities for farmers.

International audience; Consumers are being encouraged to increase the proportion of plant protein in their diets to enhance the sustainability of food systems. One approach is to develop plant-protein-rich foods that are acceptable to consumers. This study examined French people’s reactions to cheese alternatives—new fermented products that mixed animal and plant protein sources. We conducted experimental sessions with 240 French participants to assess their responses to three fermented products containing different percentages of yellow pea and cow’s milk. First, we asked the participants to blind-taste the three products and solicited hedonic scores of products. We then provided the participants with simple information about the products’ composition and asked them to taste and score the liking of the products a second time. We also asked consumers to estimate their willingness to pay (WTP) for each product before and after revealing additional information about the nutritional or environmental benefits of consuming pea-based foods. The product with the lowest percentage of pea and the highest percentage of milk received the highest hedonic scores, and WTP was correlated with the hedonic scores. The additional information about the nutritional and environmental benefits of pea-based foods led to significant increases in WTP for two of the fermented products, but not for the least preferred product, namely the one with the highest percentage of pea. This finding suggests that participant reactions to information depended on hedonic preferences.; Les consommateurs sont encouragés à augmenter la proportion de protéines végétales dans leur alimentation afin d'améliorer la durabilité des systèmes alimentaires. Une approche consiste à développer des aliments riches en protéines végétales acceptables pour les consommateurs. Cette étude examine les réactions des Français face aux alternatives au fromage - de nouveaux produits fermentés mélangeant des sources de protéines animales et végétales. Nous avons mené des sessions expérimentales avec 240 participants français pour évaluer leurs réponses à trois produits fermentés contenant différents pourcentages de pois jaunes et de lait de vache. Tout d'abord, nous avons demandé aux participants de goûter à l'aveugle les trois produits, et nous avons sollicité leur jugement hédonique. Nous avons ensuite fourni aux participants des informations simples sur la composition des produits et leur avons demandé de goûter à nouveau, en notant le goût des produits une seconde fois. Nous avons également demandé aux consommateurs d'estimer leur consentement à payer (CAP) pour chaque produit avant, et après avoir révélé des informations supplémentaires sur les avantages nutritionnels ou environnementaux de la consommation d'aliments à base de pois. Le produit avec le pourcentage le plus bas de pois et le pourcentage le plus élevé de lait a reçu les scores hédoniques les plus élevés, et les CAP étaient corrélés aux scores hédoniques. Les informations supplémentaires sur les avantages nutritionnels et environnementaux des aliments à base de pois ont conduit à des augmentations significatives du CAP pour deux des produits fermentés, mais pas pour le produit le moins préféré, à savoir celui avec le pourcentage le plus élevé de pois. Cette découverte suggère que les réactions des participants à l'information dépendent des préférences hédoniques.

This study compared the use of pork backfat (PF) and fat-tailed sheep tail and backfat (SF) on the physicochemical, fatty acids and sensory attributes of warthog cabanossi. There were no differences between weight loss during drying, moisture content, pH, water activity, salt content and lipid oxidation between the cabanossi types. However, protein and ash contents were higher in PF cabanossi whilst fat content was higher in SF cabanossi. The PF cabanossi had higher polyunsaturated fatty acids (especially n-6), lower monounsaturated fatty acids whilst the saturated fatty acid content was similar between the two cabanossi products. The n-3:n-6 ratio was more beneficial in the SF cabanossi. The descriptive sensory analysis showed two distinct products where PF cabanossi scored higher for most attributes. Although SF cabanossi scored less for these attributes, this cabanossi had unique and acceptable sensory attributes. This study concluded that fat-tailed sheep tail and backfat could be used to produce a unique cabanossi product of acceptable quality.

The process of supermarketization in emerging countries does not imply convergence in shopping practices. Based on a qualitative study in Hanoi, Vietnam, this paper adopts a shopping-as-practice approach with a specific focus on factors influencing practices. Seventy-night interviews were conducted in six urban districts of Hanoi. The results allowed to identify five types of shopping practices of differing natures and degrees of cross-shopping, and different strategies used to accomplish these practices, dominated by constraints or based on trust. The analysis showed the relationships between the factors and (1) shopping and cross-shopping strategies and (2) the dimensions of shopping practices. These findings deepen the current understanding of shopping and cross- shopping practices in the context of emerging markets. This paper also provides recommendations regarding retail policy and development in Vietnam.; Le commerce de détail au Vietnam a connu des changements notables ces dernières années. Bien qu'il soit un pays à prédominance agricole, il devrait être le marché à la croissance la plus rapide pour les magasins de proximité en Asie d'ici 2021. Alors que la plupart des études sur le marché au Vietnam se sont concentrées sur les choix individuels entre les formats traditionnels ou modernes, certaines études sont axées sur les pratiques d'achat des consommateurs dans le cadre de leur vie quotidienne. Ces recherches, cependant, n'ont pas envisagé le cross-shopping, ne se concentrent pas sur les individus et n'étudient pas les différentes dimensions des pratiques. Le but de cette étude est donc de fournir une compréhension plus approfondie des consommateurs urbains dans un marché émergent, de leurs stratégies de choix et / ou de combinaison de différents formats de vente au détail pour acheter des produits frais, et des facteurs affectant leurs pratiques d'achat. L'étude a été réalisée pour fournir un aperçu de la façon dont les habitants urbains de Hanoi choisissent où acheter des légumes et pourquoi ils font ce qu'ils font. En conséquence, les pratiques de shopping et de cross-shopping ont été étudiées en relation avec les individus qui les pratiquent. Des entretiens individuels utilisant des questions semi-ouvertes avec soixante-dix neuf participants ont été réalisés pour explorer, décrire et comprendre les pratiques de shopping et cross-shopping des acheteurs de légumes frais. La méthode de recherche qualitative a été utilisée comme approche clé pour développer une compréhension globale des phénomènes liés à l'alimentation du point de vue des participants à la recherche. Cette étude a exploré les relations entre les facteurs liés aux pratiques d'achat et les stratégies d'achat, ainsi que les dimensions des pratiques d'achat. Les relations sociales entre les acteurs du marché semblent avoir des caractéristiques particulières qui proviennent du contexte culturel plus large de l'Asie du Sud-Est, de sa tradition de collectivisme et de réciprocité, et des événements de parcours de vie individuels. L'étude propose un cadre mettant en relation les pratiques d'achat, les facteurs liés et les stratégies correspondantes dans les marchés émergents et fournit également des recommandations managériales concernant la politique et le développement du commerce de détail.

The need to increase sustainability and add value to traditional foods claiming health benefits led to the introduction of key improvements in the production of hibiscus beverages in Senegal. The physicochemical and sensory properties of three resulting products (an under-vacuum concentrate, a dilute-to-taste syrup and a ready-to-drink infusion) were assessed, vis-à-vis those of conventionally manufactured beverages, and their impact on local consumer preference determined (n = 146). New beverages had more intense, redder colour and higher monomeric anthocyanin content, total phenolic content and antioxidant capacity. Moreover, their colour evaluations by trained panellists were mainly linked to colour density and anthocyanin/polyphenol content, while flavour assessments were associated to titratable acidity and sugar-to-acid ratio. Consumer evaluations, in turn, were driven by the beverages’ red colour intensity, aroma strength and balance between sweetness and acidity. This explained why they overwhelmingly preferred the under-vacuum concentrate, regardless of their age, gender or frequency of hibiscus beverage consumption.

Food system transformation requires major changes in food consumption practices. Consumers could play central roles to stimulate these changes, which needs to be fully recognized. Multi-stakeholder R&I efforts should focus more on the interactions between individual, contextual and policy factors influencing consumption patterns, with specific attention to the dynamic character of food environments. Consumers should be empowered and engaged in decision making, through co-design, co-creation, co-implementation and co-assessment.

International audience; Kitoza refers to a traditional way of preparing beef and pork in Madagascar. However, in order to improve some drawbacks previous identified, the product was submitted to a reengineering process. The acceptance and sensory profiling of improved Kitoza products among Portuguese consumers was investigated. A local smoked loin sausage was selected as basis for comparison. Firstly, a Focus Group study was performed to identify sensory descriptors for Kitoza products and explore product perception. Subsequently, a Flash Profile and a consumer sensory acceptance study were conducted. Flash Profile's results showed that beef-and pork-based Kitoza products investigated differed considerably in all sensory dimensions. The Portuguese sausage was characterized as having a more intense and lasting after taste, as well as displaying a higher degree of (meat) doneness. The acceptance study yielded higher overall liking ratings for pork-than for beef-based Kitoza, although the Portuguese sausage remained the most appreciated product.
