Summary: Feruloyl oligosaccharides (FOs), functional oligosaccharides with the physiological activities of both ferulic acid and oligosaccharides, were prepared by fermenting wheat bran with Bacillus amyloliquefaciens IT-45. Under optimized fermentation conditions, FOs showed high antioxidant activity against ABTS, DPPH, and hydroxyl radicals, demonstrating their potential application.

Summary: This study compared the effects of traditional hydrolysis, traditional extrusion, and enzymatic extrusion on the yield of feruloyl oligosaccharides (FOs) in rice bran. It was found that both traditional extrusion and enzymatic extrusion significantly increased the yield of FOs, with enzymatic extrusion achieving the highest yield of 5.78%. Microscopy analysis showed that extrusion damaged the cell wall of bran, enhancing the accessibility of xylanase to arabinoxylan and increasing the yield of FOs. Spectroscopy analysis indicated that FOs obtained from different pretreatments had similar structures. This study provides an efficient method for the industrial production of FOs.

Summary: This study found that feruloyl oligosaccharides (FOs) can enhance the intestinal antioxidative capacity of rats by modulating the MAPKs/Nrf2 signaling pathway and gut microbiota. FOs increased the activity of antioxidative enzymes and the content of glutathione in the jejunum, and upregulated the expression of antioxidant-related genes. Additionally, FOs administration altered the composition of the cecal microbiota, which was closely correlated with the jejunal antioxidative capacity of rats.

Summary: This study investigated the effects of feruloyl oligosaccharides (FOs) from rice bran on the gel properties, microstructure, and sensory properties of grass carp surimi gel. The results showed that FOs decreased the whiteness but improved the water-holding capacity and breaking force of the surimi gel. FOs also increased the hardness and chewiness of the gel, but had no significant effect on the springiness and cohesiveness. Furthermore, FOs promoted the aggregation and uniform distribution of myofibrillar proteins in the gel, resulting in a more compact and ordered network structure.

Summary: This study investigated the effects of dietary feruloyl oligosaccharides derived from fermented wheat bran (FOs-FWB) on lamb traits, meat quality, fatty acid composition, and expression of lipogenic genes. The results showed that lambs supplemented with FOs-FWB had lower shear force, higher protein content, and lower fat content in their muscles. Moreover, FOs-FWB supplementation increased the proportions of certain fatty acids and stimulated the expression of lipogenic genes in the muscles.

Summary: According to PlasticEurope, global plastics production reached 390.7 million tons in 2021. Unfortunately, a large portion of these plastics end up as waste in the ocean or on land due to their non-biodegradable nature. This study focused on evaluating the internalization rates, cytotoxicity, and genotoxicity of polystyrene nanoparticles (PS-NPs) in human peripheral blood mononuclear cells (PBMCs) in vitro. The results showed that while PS-NPs did not have a cytotoxic effect on PBMCs, they did induce primary DNA damage and micronucleated cells, indicating their genotoxic potential.

Summary: This study evaluated the effects of Ganoderma lucidum fruiting body dry extract (GLE) on human liver and kidney tumor cells as well as peripheral blood lymphocytes. The results showed that low concentrations of GLE increased lymphocyte viability while high concentrations were toxic to lymphocytes. On the other hand, low concentrations of GLE exhibited cytotoxic activity and induced DNA damage in tumor cells. Therefore, G. lucidum has potential antitumor effects and could be developed into a therapeutic agent for cancer.

Summary: Wheat bran extracts (WBE), consisting primarily of feruloyl oligosaccharides (FOs), have been approved by the FDA for use in microcapsules made with octenyl succinate anhydride-modified starch (OSA-starch) as a protective wall material for beta-carotene (BC) against oxidation. The retention and antioxidant properties of the microcapsules were studied in vivo and in vitro, and it was found that these characteristics were dependent on the amount of WBE in the wall material. In mouse serum and liver, the in vivo antioxidant properties were regulated positively at a dosage similar to that found in wheat grain, but became imbalanced at higher dosages. These findings demonstrate that WBE is a beneficial component for improving the antioxidant environment during storage and consumption, providing a theoretical basis for its industrial application in microcapsules.

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: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

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.
