The sun-dried method is popular for producing dried Sergestid shrimp in Vietnam, but maintaining consistent product quality across seasons is challenging due to its dependence on weather conditions. A previous study used convection drying at a laboratory scale. In this study, the laboratory scale was upgraded to a commercial scale, and recovery efficiency and Sergestid shrimp images were recorded during production stages. Parameters were adjusted for economic efficiency and convenience. Results showed a decrease in recovery efficiency on the laboratory scale, while the commercial scale improved with washing and blanching. Overall, there was no significant difference in recovery efficiency between the commercial production (15.76 %) and laboratory scale (16.29 %). The commercial-scale dried Sergestid shrimp exhibited better colour than the laboratory-scale product. The product met food safety and quality criteria according to Vietnamese standards. Microorganisms such as Coliforms, E. coli, B. cereus, C. perfringens and salmonella, and total number of yeast and mold spores, were not detected in the product. On the other hand, the product of commercial production contained 256 kcal 100 g−1 of energy and a protein content of 55.50 ± 0.33 %. These findings form a foundation for scaling up production and assessing economic feasibility. Adjusting production parameters using larger equipment contributes to achieving optimal production efficiency and economic benefits.

Strawberries are amongst the most desirable fruits with a rich flavour, appealing taste, high fibre content and many other health benefits. Diets rich in dietary fibre provide many health benefits. In the present work, strawberry juice was prepared in two batches, one with preservative sodium benzoate (treated) and another without (untreated). Prebiotic fibre i.e., apple pomace was added to both batches in concentrations of 5%, 8%, and 11%. Dietary fibre in both batches was analysed by enzymatic-gravimetric method. The additional analyses included pH, acidity, total soluble solids (TSS), colour, total phenolic content (TPC), antioxidant, ascorbic acid, anthocyanin, microbial and sensory parameters. Dietary fibre was increased significantly in all the treatments as well as TS, while pH and acidity were not affected. Ascorbic acid, anthocyanin, antioxidant, total phenolic content, and sensory analysis of treatment 2 (T2, 8% treated) showed the best results. The microbial load on the other hand increased more in the untreated batch. The T2 treatment of both the batches was given ultrasound treatment. The sonication temperature (20 oC), frequency (20 kHz), and power (650 W) were kept the same, and the time was varied (0, 15, 30, 45, and 60 minutes). Dietary fibre showed a slight increase as fibre became more soluble by cavitation in sonication while pH acidity and TSS were not significantly affected. Anthocyanin increased, but only at lower sonication times. Antioxidants, total phenols, and colour and sensory parameters were significantly improved with sonication time. Similarly, the microbial load was reduced significantly.

Labaneh (strained yogurt) is a traditional dairy product. It is usually produced without chemical preservatives as Jordanian standards for this product prevent their addition. Its shelf life is limited to two weeks. This research aims to develop the shelf life of labaneh using eco-friendly methods, via the addition of protective probiotic cultures. Protective probiotic cultures were prepared by activating DVI freeze-dried Propionibacterium freuendereichii, subsp. shermanii and Lactobacillus paracasei in sterilized skim milk. Fifty kg of fresh milk was divided into two portions, the first containing the traditional yogurt starter culture (2%) and the second processed by adding both the starter (2%) and protective probiotic cultures (1%). After fermentation, two types of yogurts were produced, and refrigerated for several hours. They were then salted, strained separately to about 25% total solids in a special cloth to produce labaneh paste. The paste was then distributed into two groups of sterilized jars (21 for each) and placed in refrigerated storage. Both types of labaneh (traditional and developed) were evaluated at different time intervals of refrigerated storage (0, 3, 7, 10, 14, 21, 30 days) for their counts of coliform bacteria, yeast and mould, and lactic acid bacteria (LAB), and for their pH, ash, acidity, moisture, protein, fat and titratable acidity. The probiotic count was also evaluated for the developed labaneh. The shelf life of the developed labaneh was determined based on the acidity, yeast and mould counts and organoleptic characteristics. No obvious and significant undesirable changes were seen at 30 days of refrigeration or went beyond the Jordanian standard for the developed labaneh, compared to the traditional one which started to spoil after 14 days. No coliform bacteria were found after 30 days of refrigerated storage in the traditional and developed labanehs. The counts of yeast and mould were generally higher in the traditional labaneh than in the developed one, while the number of LAB was lower in the traditional labaneh than in the developed one. The pH and moisture of the developed labaneh were generally lower than that of the traditional labaneh, but the titratable acidity, ash, protein and fat were higher in the developed one. Regarding the sensory properties, most of the panelists organoleptically preferred the developed one during the storage period. Therefore, it is concluded that the protective probiotic cultures were effective in extending the shelf life of labaneh.

Regarding neonates and infants, the videofluoroscopy swallowing study is always conducted with liquids impregnated with a radiopaque material in varied proportions and thickenings. Variations in thickening and barium concentration are known to change the swallowing function. The present study aimed to analyze the rheological and macroscopic properties of barium contrast and liquids commonly used in Brazil with infants under six months old. This study was approved by the Ethics Committee under certificate number 63361616.2.0000.5482. Rheological measurements were performed on samples of breast milk and infant formulas, pure, with thickener, impregnated with liquid barium sulfate, as well as a pure barium sulfate sample. The data collected showed similar viscosity rates between breast milk and the infant formulas Aptamil and Enfamil. Impregnating them with 20% and 33% liquid barium sulfate increased their viscosity. However, they remained in the same classification, despite the quantitative differences in their apparent viscosity. The regular products, in formulation with thickener and thickener plus 20% barium, showed an increase in apparent viscosity close or twice to that of Enfamil A.R. impregnated with 33% barium sulfate. The study allowed a more in-depth understanding of how the products behave at strain rates consistent with the conditions when swallowing. The results indicated in this study confirm the need for knowledge and care in preparing liquids to be offered in videofluoroscopy swallowing studies with neonates and infants. They also emphasize the importance of objectively measuring the viscosities of videofluoroscopic fluids, matching them with the liquids to be prescribed in their diets.

Short food supply chains (SFSCs) are a still developing phenomenon in the world of food production and distribution. They involve a direct connection between local farmers and consumers, with minimal intermediaries involved. SFSCs have gained significant interest in recent years due to their potential to promote sustainable agriculture and support local communities. As a result, many governments, organisations, and individuals have been exploring ways to develop and promote these chains as a viable alternative to conventional food supply chains. However, it is still unclear how SFSCs products are perceived differently by producers and consumers: what makes SFSCs products more desirable? Starting from a European project (SmartChain), answers from twenty questionnaires from SFSCs actors across Europe were analysed to understand the strengths and weaknesses of SFSCs products according to the producers. From their answers, 18 quality criteria referred to SFSCs products were obtained and then proposed to consumers through a second questionnaire. The second questionnaire aimed to better understand whether the producers’ points of view matched the consumers’ points of view. From the analysis of the results, it was possible to understand what criteria were considered quality attributes by producers and consumers. Organic production and the presence of both trained and vulnerable personnel were not particularly relevant to the quality perception of SFSCs products. The storage method, the assortment range, and the processing of the products were not evaluated as quality criteria. The consumers who were interviewed perceived the quality of a food product coming from an SFSC linked to the characteristics of the social context of the product. They associated products sold in SFSCs with non-processed food. Overall, such a survey can be considered a useful tool to deepen our knowledge about short food supply chains and offers several ideas for further studies and analysis.

Our study focuses on describing the zootechnical characteristics of dairy cattle farms and conducting serological research on brucellosis in ruminants. To this end, a survey was conducted in 119 dairy farms, collecting 363 serum samples from March to December 2022. The study was carried out in the Doukkala region, within the province of El Jadida and Sidi Bennour, Morocco. The results indicate that 90.8 % of operators are owners with 37.8 % having no formal education. The cattle population consists of 67.8 % crossbreed and 31.4 % imported breed. A significant proportion of cows are purchased from the souk (57.5 %). The proportion of cows with a history of abortion is higher (p=0.01) in crossbreed cattle than in the imported breed. Notably, only 10.2 % of farmers are aware of bovine brucellosis. The detection of brucellosis was carried out using the Rose of Bengal test on serum samples collected from the blood. The study revealed a low rate of brucellosis cases (0.8 %) in a sample of 363 cows. This is attributed to the previous enforcement of health and hygiene measures by dairy farms. However, the lack of education and awareness about this disease and the importance of hygiene in dairy production could pose risks to production and consumer safety.

Snakehead fish (Chana striata) is one of the important protein sources among Indonesian people. However, the shelf life is short leading to limited use of fresh snakehead fish. This study aimed to analyse the effect of vacuum packaging and addition of salt on the sensory properties, total plate count, water activity and pH of fresh snakehead fish. The fish was salted (NaCl) at various concentrations, including 0, 5, 10 and 15%, and kept for 14 days at refrigeration temperature (± 3°C). Sensory evaluation, total plate count (TPC) and water activity (aw) measurements, and pH analysis were performed at day 0, 7 and 14. All groups with salt addition exhibited a significantly slower decrease in the mean scores (9-point hedonic scale) of color, aroma, appearance and texture (p < 0.05), with the decrease for all sensory properties detected at day 7 of storage. In microbial tests, a significant increase in TPC was observed in the groups with 0% and 5% salt addition (p < 0.05). The group with 15% salt addition showed the lowest water activity. Also, the group without salt addition had the highest pH value. This study demonstrated that addition of salt to snakehead fish might gives beneficial effects on the shelf life of a vacuum packaged product. However, the optimum shelf life using vacuum packaging and salt addition needs further study.

Many studies related to the therapeutic effect of black garlic (BG) have been carried out on cancer, diabetes, neurodegenerative, cardiovascular, dyslipidemia and other diseases. This investigation was conducted to examine the effect of BG supplements on the lipid profile and blood glucose of rats fed a customary diet (non-high fat diet). A fermented black garlic product was extracted by a maceration method and its phytochemical components were analyzed using LCMS. Black garlic extract was given to healthy rats with a normal feed for 14 days. Twenty-four rats were divided into 4 groups of 6 rats. As a control, group A was given aquadest (placebo), and groups B, C, and D were given BG extract at a dose of 15 mg/kg BW, 30 mg/kg BW, and 45 mg/kg BW, respectively. On day 15, blood was taken from the retro-orbital plexus of the rats to measure the total levels of cholesterol, High-Density Lipoprotein-Cholesterol (HDL-C), Triglyceride (TG), Low-Density Lipoprotein-Cholesterol (LDL-C) and glucose. Black garlic made by fermentation at 80°C for 8 days contained more monosaccharides, disaccharides and oligosaccharides than fresh garlic. Black garlic contained 32 types of organosulfur compounds, and the 5 most abundant compounds were allicin (5.813%), allin (4.993%), isoallin (3.77%), cycloalliin (3.163%) and (-) S-allyl-L-cysteine (2.022%). Black garlic extract administration was able to maintain blood glucose homeostasis in rats fed a normal diet (non-high fat diet). Levels of total cholesterol, triglyceride, and LDL-C were significantly decreased in groups administered black garlic compared to the control group, whilst the level of HDL-C increased significantly in groups administered black garlic compared to the control group.

Shifting from meat consumption is critical for future dietary evolution. Mainstream newspapers and social media are the leading platforms for expressing this opinion. By analysing the media discourse, the proponents of the shift from meat, to plant-based meat and cultured meat were identified. The objectives were: a) to identify themes, word frequencies, and sentiment related to meat substitutes, b) to determine Chinese perceptions of the two meat substitutes, and c) to determine which food functions are of concern to Chinese consumers. Between July 2016 and July 2022, the researcher gathered data from People’s Daily and China Daily online outlets and user comments. 574 news articles and 2,345 online comments were extracted. Three techniques were applied: sentiment analysis, thematic analysis, and word cloud analysis. The results revealed that newspapers reported positively on meat substitutes, yet user comments showed negative public perception. Chinese people held positive attitudes toward plant-based meat and negative attitudes toward cultured meat. Thus, the insights from the media discourse provided valuable indicators for stakeholders to develop sustainable food education and consumption strategies.

Non-alcoholic beverages often contain various constituents and additives, influencing both their nutritional profiles and functional attributes. Given the ubiquity of these beverages and their potential health implications, rigorous quality checks are indispensable to ascertain compliance with health and safety standards. This research aimed to quantify caffeine and phosphoric acid levels in a diverse array of soft drinks from Kosovo’s market. To achieve this, 41 distinct non-alcoholic beverage samples from the local market were scrutinized. Caffeine concentrations were determined via UV-Vis spectrophotometry, while potentiometric titration was employed to assess phosphoric acid levels. As expected, energy drinks in Kosovo contained markedly higher caffeine concentrations compared to carbonated soft drinks and ice-tea variants. On the other hand, based on the results, analysed energy drinks showed somewhat greater caffeine contents than those reported in packaging of the beverage samples. Our study showed that a significant portion of the samples (21.95% for caffeine and 9.76% for phosphoric acid) did not conform to the standards set by EU 1169/2011 regulation or the EU 1333/2008 regulation. These findings underscore the urgency for relevant food safety authorities to implement rigorous oversight and enact appropriate protective measures. It is also imperative for the Kosovo National Food Safety Authority to craft specific regulations stipulating permissible additive concentrations, especially for caffeine and phosphoric acid, in non-alcoholic beverages.
