Summary: The effects of adding Hibiscus sabdariffa by-product (2-5%) and Pleurotus djamor powder (5-7.5%) as meat replacers to beef patties were analyzed. The addition of these non-meat ingredients decreased moisture and increased fiber content, without affecting the protein level. While the roselle by-product had limited antioxidant effect, Pleurotus djamor favored oxidation processes. The samples with these ingredients had lower microbial counts, but were significantly affected in terms of texture and sensorial parameters.

Summary: The human gastrointestinal tract contains diverse microorganisms that interact with the host and play important roles in regulating metabolic processes. While the gut bacteriome has been extensively studied, there is increasing interest in understanding the influence of other microbial groups, such as the gut virome and phages, on the host immune system and metabolic functions. Investigating the role of virome-rectification-based therapies in various diseases is also important. In future research, stool metagenomic investigations should focus on identifying bacteria and phages, as well as studying their correlation networks, to gain a better understanding of gut microbiota activity in metabolic disease progression.

Summary: This study investigated the use of pitaya extracts in biodegradable packing films to inhibit quality loss in fish muscle during refrigerated storage. The experiments utilized pitaya-gelatin films for hake muscle storage and pitaya-polylactic acid (PLA) films for Atlantic mackerel muscle storage. The results showed that the presence of pitaya extract led to a significant inhibitory effect on lipid damage, microbial activity development, and growth of bacteria in both systems. The preservation effects were attributed to the presence of betalains and phenolic compounds in the pitaya extracts.

Summary: Various studies have found that specific groups or dietary compounds play a role in the onset and progression of obesity, and gut microbiota serves as a mediator between these compounds and the associated inflammation. This study aimed to evaluate the dietary intake of overweight, obese, and normal-weight individuals and analyze their gut microbiota profile in relation to changes in Body Mass Index (BMI) and diet. The results showed significant differences in fiber and monounsaturated fatty acids (MUFAs) intake among different BMI groups, with better intake adequacy observed in the normal-weight group. The analysis of gut microbiota revealed distinct microbial composition in overweight and obese individuals compared to normal-weight individuals, with specific genera identified as biomarkers for each group.

Summary: The proper functioning of the gastrointestinal tract is crucial for strengthening the immune system. Lactic acid microorganisms are necessary for this proper functioning, mainly sourced from dairy products. However, lactose digestibility poses a problem, leading to the interest in alternative sources and carriers of probiotics. Protein marshmallow can serve as such a carrier due to its dietary and natural properties. This study aims to identify the dependence of technological factors on the rheological properties of the product and the growth of lactic acid microorganisms in confectionery products enriched with lyophilised strains.

Summary: This study evaluated the phytochemical constituents, antioxidant, and antibacterial properties of Kappaphycus alvarezii and Cymodocea serrulata. Both seaweeds contained flavonoids, tannins, phenolic compounds, glycosides, steroids, carbohydrates, and ashes. Alkaloids were only found in K. alvarezii. The chloroform extracts of both seaweeds exhibited antagonistic efficacy against Bacillus subtilis, Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio harveyi, and Klebsiella pneumoniae. GC-MS analysis revealed the presence of numerous bioactive compounds in both seaweeds, which contributed to their antioxidant and antibacterial activities. Based on the results, K. alvarezii and C. serrulata could be considered as valuable sources of nutritional and medicinal ingredients.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
