food waste ,food waste prevention ,focus groups ,interventions ,young people - Abstract
Young consumers are often described as innovative and concerned about the environment. However, their practices sometimes are not strong enough, which are described as the attitude-behavior gap and are seen in significant amounts of food waste. The objective of this study is to focus on food waste among young consumers in high-income countries and to outline the main determinants of food waste generation. Qualitative data gathered from nine focus groups in Lithuania, Finland and Denmark (2021-2022) contribute to formulating potential intervention to decrease food waste behavior within this segment. The article provides a substantial literature review on food waste and discusses recommendations for possible interventions and further research to solve the attitude-behavior gap. The findings show four specific fields for potential solutions, related to (1) special occasions, (2) assessing food quality, (3) kitchen habits, and (4) shopping habits. Our contribution is discussed at the end of the article.

VEGETABLES ,ALLERGENS ,RAW materials ,SUSTAINABLE development ,HIGH pressure (Science) - Abstract
It is more and more necessary to select and provide model systems that fit to personalised nutrition, avoiding usage of main allergens. It can be achieved by combining raw materials of various origins, extracted using sustainable technologies, but at the same time maintaining the qualitative and quantitative characteristics of the product acceptable to specific user groups. Our research is distinguished by the processing of vegetable presscakes and their combination with protein matrices, as well as the determination of the properties of these matrices. New methods of raw material processing can increase the bioavailability of essential nutrients in the raw material and in the matrix of final products and can promote positive changes in the microbiota. The consumption of fibrous materials is constantly growing, new sources of fibres are being sought, fibre-enriched food matrices are being developed, and consumer acceptability is being assessed. The aim of this study is to analyse the possibilities of applying innovative wet extrusion technology to produce raw meat analogs by composing products with optimal composition and sensory properties, testing a new, nonthermal high-pressure processing preservation method. When developing models for the processing of matrices of plant and animal raw materials using high-pressure technology, for varying parameters of pressure, time, packaging and duration, it was established that the high-pressure exposure model must be selected taking into account the composition and properties of the product, the purposeful application of other microorganism inhibiting factors to achieve synergistic action, because exposure to high pressure alone does not ensure the destruction of bacteria in a model system. To create matrixes of raw materials of balanced composition of vegetable raw material, berry press-cakes and meat analogues of legume flour, five variations of balanced composition and nutritional value were created based on beetroot, pumpkin, carrot, black currant, Jerusalem artichoke and legume matrix.

- Abstract
The linear pattern of production-consumption-disposal of cities around the world will continue to increase the emission of pollutants and stocks of waste, as well as to impact on the irreversible deterioration of non-renewable stocks of raw materials. A transition towards a circular pattern proposed by the concept of ‘Circular Cities’ is gaining momentum. As part of this urban transition, the emergent use of Nature-based Solutions (NBS) intends to shift public opinion and utilize technology to mitigate the urban environmental impact. In this paper, an analysis of the current research and practical investments for implementing NBS under the umbrella of Circular Cities is conducted. A combined appraisal of the latest literature and a survey of on-going and completed National-European research and development projects provides an overview of the current enabling tools, methodologies, and initiatives for public engagement. It also identifies and describes the links between facilitators and barriers with respect to existing policies and regulations, public awareness and engagement, and scientific and technological instruments. The paper concludes introducing the most promising methods, physical and digital technologies that may lead the way to Sustainable Circular Cities. The results of this research provide useful insight for citizens, scientists, practitioners, investors, policy makers, and strategists to channel efforts on switching from a linear to a circular thinking for the future of cities.

Biogeninių aminų tiramino, putrescino ir histamino kiekiai buvo nustatyti efektyviosios skysčių atvirkštinių fazių chromatografijos (HPLC) metodu šaltai rūkytose dešrose, pagamintose su biologiniais priedais: 1) polisacharidų kilmės prebiotiku, 2) polisacharidų kilmės prebiotiku ir probiotine raugų kultūra Bitec LS25, į kurios sudėtį įeina Lactobacillus sake LS25, 3) probiotine raugų kultūra Bitec LS25. Tik ką pagaminti mėginiai, atrinkti įmonėje, laikyti šaldytuve 6 ± 2oC ir tirti po 0, 15, 20, 35 ir 120 parų. Šiuo laikotarpiu buvo stebima biogeninių aminų susidarymo dinamika. Tirtuose mėginiuose bandymo pradžioje nustatytas skirtingas atskirų frakcijų biogeninių aminų kiekis. Daugiausia putrescino, histamino ir tiramino rasta dešrų gaminiuose su prebiotikais. Bandymo pabaigoje didžiausia putrescino koncentracija nustatyta šaltai rūkytose dešrose, pagamintose su prebiotikų priedu, o mažiausia − su probiotinių kultūrų priedais. Daugiau histamino susidarė dešroje su probiotinėmis kultūromis ir prebiotikų priedu, o tiramino – su prebiotiniu priedu. Koliforminės bakterijos, Staphylococcus aureus ir Clostridium perfringens dešrų bandiniuose bandymo pradžioje nebuvo aptiktos nė viename iš dešrų variantų. Laikymo metu šie mikroorganizmai taip pat nesivystė. Pienarūgštės bakterijos šaltai rūkytose dešrose su probiotine ir probiotine kultūra bei prebiotiku išsilaiko visas 120 parų, jų lygis siekia šimtus milijonų KSV/g. Tyrimo metu nustatyta, kad probiotinė kultūra Bitec LS25, į kurios sudėtį įeina Lactobacillus sake LS25, turėjo įtakos biogeninių aminų susidarymui tiek gaminio fermentacijos, tiek ir jo laikymo metu, bet nebuvo koreliacijos tarp pienarūgščių bakterijų kiekio ir biogeninių aminų susidarymo intensyvumo., The amounts of biogenic amines putrescine, histamine and tyramine were determined by HPLC method in samples of a cold smoked sausages with biological additives: polisaccharide origin prebiotic, mixture of polisaccharide origin prebiotic and probiotic culture Bitec LS25 contained Lactobacillus sake LS25 and probiotic culture Bitec LS25. Samples were selected from manufacture and were tested after 0, 15, 20, 35 and 120 days refrigerated storage at 6 ± 2 oC. During this period the production of biogenic amines was studied. At the start of our study the different levels of biogenic amines fractions in samples were tested. The highest amounts of biogenic amines were determinated in sausages with prebiotic. At the end of storage the highest concentrations of putrescine and tyramine were estimated in sausages with prebiotic and the lowest – with probiotic culture Bitec LS25. The highest level of histamine formation was registered in sausages with mixture of probiotic and prebiotic. At the beginning of our study and during the storage the endogenous coliform bacteria, Staphylococcus aureus and Clostridium perfringens in samples of a cool smoked sausages were not determined. The lactic acid bacteria in level of 108 CFU/g were dominated in a cold smoked sausages with probiotic culture and in sausages with mixture of probiotic culture and prebiotic during the storage for 120 days. Inclusion of Lactobacillus sake LS25 to a cool smoked sausages influenced the biogenic amines formation during fermentation process and storage for 120 days, but there was no correlation between count of lactic acid bacteria and intensity of biogenic amines formation.

Ištirtos probiotinių pienarūgščių kultūrų naudojimo fermentuotų dešrų gamyboje galimybės ir jų įtaka gaminio kokybei bei saugumui. Fermentuotų dešrų modelinės sistemos pagamintos tokios sudėties: liesa jautiena bei kiauliena ir kiaulienos lašiniai lygiomis dalimis. Pirmoji ir trečioji fermentuotų dešrų modelinės sistemos pagamintos su nitritine druska (2,5 %), o pirmoji ir antroji – su Bitec LS25 plus mišiniu, į kurio sudėtį įeina Lactobacillus sake LS25. Įvertinta Bitec LS25 plus mišinio įtaka pienarūgščių bakterijų, koliforminių bakterijų skaičiaus, nitritų ir biogeninių aminų kiekio pokyčiams. Nustatyta, kad Lactobacillus sake LS25 paspartina terpės pH kritimą jau pirmosiomis dešrų brandimo paromis, skatina pienarūgščių bakterijų skaičiaus didėjimą. Lactobacillus sake LS25 naudojimas leidžia išvengti koliforminių bakterijų skaičiaus šuolio brendimo pradžioje, kuris aiškiai pastebimas dešrose be pienarūgščių bakterijų. Brandinimo metu buvo pastebėtas (p, The production of fermented foods is based on the use of starter cultures, for instance, lactic acid bacteria, to initiate rapid acidification of the raw material. Recently, new started cultures of lactic acid bacteria with industrially important functionality are being developed. Examples are lactic bacteria that produce antimicrobial substances, sugar polymers, sweeteners, aromatic compounds, vitamins, or those having probiotic properties. The study was undertaken to explore the possibilities of interpolating the probiotic concept into the product range of fermented sausages. The considerable influence of the starter culture Lactobacillus sake LS25 on the microbiological, physical and chemical traits of the dry fermented sausages was observed. The quantitative significant increase in the number of lactic acid bacteria was determined during ripening (day 2 and day 4) in fermented sausage with probiotic starter cultures. The use of Lactobacillus sake LS 25 makes it possible to avoid the increase in coliform bacteria count at the initial stages of ripening in fermented sausage. The sausage with natural lactic acid bacteria microflora showed its depressing influence on coliforms only on the fourth day of ripening, when the lactic acid bacteria count became equal to the amount in fermented sausage batches with Lactobacillus sake LS 25. The use of Lactobacillus sake LS 25 suppresses the biogenic amine formation in fermented sausage during ripening: the quantities of putrescine, tyramine and histamine were 87.0, 62.2 and 68.1 mg/kg, respectively. The amounts of biogenic amine in fermented sausage were twice as lower as those made without Lactobacillus sake LS 25. The use of Lactobacillus sake LS 25 induces the faster nitrite salt cleavage in fermented sausage at the first stages of ripening. A slower process was observed in fermented sausage systems made without Lactobacillus sake LS 25.

The paper provides research data on histamine content in fish and fish products purchased in a supermarket in Lithuania. The prevalence of histamine in the analyzed fish ranged from 5.00 mg kg
-1 to 240.78 mg kg-1 , with mean value of 36.97±12 mg kg-1 . Histamine levels in 16% analyzed salmon samples exceeded the limits defined in Regulation (EC) 2073/2005 (7). Such increase was influenced by seasonality: significantly higher histamine levels were found in fish after spawning than in those caught in the autumn and winter seasons. Histamine levels in salmon varied from 5.00 mg kg-1up to 240.78 mg kg-1 , In herring, the levels of histamine ranged from from 5.00 mg kg-1 up to 177.45 mg kg-1 . Smaller quantities - in a range of 5.00-102.50 mg kg-1 were found in mackerel, although this fish belongs to the species with an abundant prevalence of histidine. The levels of determined histamine in fish products were significantly higher than in fresh fish, at p <0.05. The highest levels of histamine were detected in herring products, yet they varied from 6.09 mg kg- to 177.45 mg kg-1 although the mean value was 59.89±25 mg kg-1 . Technological processing had impact on the accumulation of histamine in fish products. The smallest quantities of histamine were found in fermented fish products; slightly higher amounts, in salted dried fish, and the highest levels of histamine were determined in cold and hot smoked fish. In cold smoked escolar the level of histamine was 176.00 mg kg-1 , as well as in hot-smoked mackerel - up to 128.01 mg kg-1 . Considering the safety of fish products in relation to histamine content, herring products are the least safe as there were significantly higher levels of histamine found (p<0.05) in these products than in other analyzed products.

- Abstract
The increase of the fishing capacity and cultivated fish quantities at the aqua farms introduce large amounts of fish for manufacturing. As a result, the fish-processing industry produces much more fish rest raw materials. Fish rest raw materials are resulting directly from fishing vessels and fish processing plants, when eviscerating fish, separating heads, viscera, fins and other non-food grade fish body parts or low value species fish. Under the requirements of bio economics for sustainable food technologies development the reuse of food rest raw materials and introduction back to agro and food processing streams is of a highly importance and prioritized issue by biological, ecological, environment, economical means not only in Lithuania, but in European and global markets as well.

The aim of this work was to investigate the most promising natural antimicrobials effective for the growth suppression of Xanthomonas spp. bacteria. The research objects were Xanthomonas spp. strains isolated from tubers and stem of plants growing in Lithuania: Xanthomonas translucens NRCIB X6, X. arboricola NRCIB X7, NRCIB X8, NRCIB X9, and NRCIB X10; the supernatants of lactic acid bacteria Lactococcus lactis strains 140/2, 57, and 768/5, Lactobacillus helveticus strains 14, 148/3, R, and 3, Lb. reuteri 3 and 7, Streptococcus thermophilus 43, Enterococcus faecium 59-30 and 41-2; endophytic bacterial strains Bacillus, Pseudomonas, and Paenibacillus spp.; and essential oils of lavender (Lavandula angustifolia), grapefruit (Citrus paradisi), pine (Pinus sylvestris), thyme (Thymus vulgaris), rosemary (Rosmarinus officinalis), peppermint (Mentha piperita), lemon (Citrus limetta), aqueous extracts of blueberries (Vaccinium myrtillus), and cranberries (Vaccinium vitis-idaea). The antimicrobial activity of tested substances was determined by agar diffusion method. Supernatants of Lb. reuteri strain 7 and Lb. helveticus strains 14, R, 3, and 148/3 were found to have a high antimicrobial activity against Xanthomonas spp. bacteria strains when compared to the positive control—1.0% copper sulfate (diameter of inhibition zones was 28.8 ± 0.7 mm). The diameter of inhibition zones of supernatants ranged from 23.3 ± 0.6 mm to 32.0 ± 0.1 mm. Thyme (2.0%) and lavender (2.0%) essential oils inhibited the growth of Xanthomonas spp. strains. The diameter of the inhibition zones was from 14.7 ± 0.8 mm to 22.8 ± 0.9 mm. The aqueous extracts of blueberries had a weak antimicrobial activity. The diameter of inhibition zones ranged from 11.0 ± 0.2 mm to 13.0 ± 0.2 mm. [ABSTRACT FROM AUTHOR]

Tyramine, purescine and histamine were determined with HPLC in cooked, cooked - smoked sausages during the self life period. Cooked sausages were taken from commercial, kept under 5±0.8 0C and investigated 1, 6, 13, 20 days after manufacturing. Cooked - smoked sausages were taken from producers, kept under 5.6±0.5 0C and investigated 1, 8, 15, 36 days after manufacturing. The presence of biogenic amines (BA) Put, His, Tyr and its relationship with microbial development (coliforms, TBC), physico-chemical indices (pH, temperature, aw, dry matter, proteins) was evaluated. The investigation of cooked sausages revealed that the highest BA content was in ‘Daktariška’ - 6.6 mg/kg, the lowest - in ‘Mažyliu’ - 0.71 mg/kg sausage. The estimation of the biogenic amines (Put, His, Tyr) revealed the tendency of the constant decrease in the biogenic amine content during the first stages of the storage followed by the increase after 20 days. The lowest level of BA in all types of samples was observed on 6 day after manufacturing, which was connection of Put reduction. Aw didn't change significantly during 20 days storage period and was comparable in all samples of the produces: ‘Daktariška’ - 0.939±0.01, ‘Originalioji’ - 0.941±0.01, ‘Mažyliu’ - 0.938±0.01. No accumulation of Coli forms was observed in all samples of the sausages during storage period. TBC increased in ‘Daktariška’ and ‘Mažyliu’ 0.8 lg (CFU) and 1.3 respectively, although reduced in ‘Originalioji’ - 0.1 lg (CFU) during 20 days storage period. The highest concentration of BA in cooked-smoked sausages was observed on 15 day after manufacturing: ‘Servelatas’ - 0.64 mg/kg. The decrease took place later, and the 36 day the BA content reached levels such as 0.50 0.21, 0.15 mg/kg in ‘Servelatas’, #x2018;Ypatingoji’, ‘Saliami’ sausages respectively. Aw values were unfavourable (0.935 - 0.923) to microflora development during the storage period. TBC increased in the cooked-smoked sausage during 36 days of storage: ‘Servelatas’ - 2.6, ‘Ypatingoji’ - 2.5, ‘Saliami’ - 2.2 lg (CFU). No accumulation of Coli forms was observed in all samples of the sausages during storage period. No big variability (6.07 - 6.73) was observed in pH values in the sausages. The reduction of Histamine was observed on 8 day after manufacturing which is in comply with TBC equilibrium at the same period of the sausages storage. [ABSTRACT FROM AUTHOR]

The linear pattern of production-consumption-disposal of cities around the world will continue to increase the emission of pollutants and stocks of waste, as well as to impact on the irreversible deterioration of non-renewable stocks of raw materials. A transition towards a circular pattern proposed by the concept of ‘Circular Cities’ is gaining momentum. As part of this urban transition, the emergent use of Nature-based Solutions (NBS) intends to shift public opinion and utilize technology to mitigate the urban environmental impact. In this paper, an analysis of the current research and practical investments for implementing NBS under the umbrella of Circular Cities is conducted. A combined appraisal of the latest literature and a survey of on-going and completed National-European research and development projects provides an overview of the current enabling tools, methodologies, and initiatives for public engagement. It also identifies and describes the links between facilitators and barriers with respect to existing policies and regulations, public awareness and engagement, and scientific and technological instruments. The paper concludes introducing the most promising methods, physical and digital technologies that may lead the way to Sustainable Circular Cities. The results of this research provide useful insight for citizens, scientists, practitioners, investors, policy makers, and strategists to channel efforts on switching from a linear to a circular thinking for the future of cities.

Chitosan is one of the most perspective biologically active ingredient, which is widely used as a food supplement. However, addition of chitosan to food products causes the problem of identification of its exact quantities in food. The study was performed to analyze the possibility of quantitative determination of chitosan added to skimmed milk, whey proteins and minced meat (raw and thermal treated). The common total nitrogen and non-nitrogen protein determination methods were used for analysis. It was determined, that chitosan created untraceable chemical compounds with skimmed milk proteins. It was concluded that non-protein nitrogen methods not allowed to determine the presence of chitosan in mixtures with milk proteins. [ABSTRACT FROM AUTHOR]
