Summary: This study investigates the digestion and fermentation characteristics of kiwifruit pomace polysaccharides (KFP) through in vitro simulated digestion and fecal fermentation. It is found that KFP retains hypolipidemic and hypoglycemic activities after digestion, and fecal fermentation alters the properties of indigestible KFP. Furthermore, fecal fermentation promotes the growth of beneficial bacteria and inhibits unfavorable bacteria, maintaining the balance of gut microbiota.

Summary: This study investigated the changes in structural properties of Ziziphus Jujuba cv. Pozao polysaccharide (JPS) during in vitro digestion and fermentation, and its effects on gut microbiota. The results showed that digestion caused a decrease in reducing sugar content and a slight increase in molecular weight. During gut microbial fermentation, the reducing sugar content initially increased and then decreased, while carbohydrate residue decreased with the release of monosaccharides. The fermentation also resulted in changes in gut microbiota composition and metabolic pathways. These findings suggest that JPS is indigestible but plays a crucial role in regulating gut microbiota and metabolic functions.

Summary: This study evaluated the potential prebiotic properties of enzymatically synthesized levan. The results showed that levan remained stable during saliva-gastrointestinal digestion but was seriously damaged during fecal fermentation. The levels of short-chain fatty acids, especially propionic acid, butyric acid, and valeric acid, increased significantly. Furthermore, levan promoted the abundance of beneficial bacteria such as Megasphaera and Megamonas genera, while inhibiting the proliferation of harmful genera such as Cedecea and Klebsiella. Overall, this study provided new insights into the potential probiotic mechanism of levan.

Summary: The aim of this study was to establish an in vitro human digestion model to investigate the degradation characteristics of a high-purity polysaccharide from Clitocybe squamulosa (CSFP2). The results showed that the reducing sugar content of CSFP2 increased and its molecular weight decreased significantly during saliva-gastrointestinal digestion. The monosaccharide composition of CSFP2 remained stable, but the molar ratios changed. The surface structure of CSFP2 changed, but its viscosity remained stable during digestion. Furthermore, CSFP2 retained its strong antioxidant capacity. The fermentation of CSFP2 by gut microbiota also led to significant changes in physico-chemical properties and increased the production of short-chain fatty acids. The relative abundances of certain microbial genera were also increased. These findings provide a theoretical basis for the development of functional foods related to CSFP2. Evaluation: 9/10

Summary: This study aimed to investigate the structural, digestion, and fecal fermentation behaviors of sea cucumber polysaccharide fermented by Bacillus subtilis Natto. Results indicated that both sea cucumber polysaccharide (SP) and fermented sea cucumber polysaccharide (FSP) were sulfated polysaccharides containing fucose. The physicochemical properties and molecular characteristics of SP and FSP were similar, but the microscopic morphology and monosaccharide composition of FSP changed after fermentation. Both SP and FSP showed similar digestion and fecal fermentation characteristics, however, their impacts on gut microbiota differed. This study provides valuable insights into the changes in the structure and digestive characteristics of sea cucumber polysaccharides caused by fermentation, with potential applications in the development of new fermented sea cucumber products.

Summary: Acid-catalyzed depolymerization is the most practical method for analyzing the subunit composition and polymerization degree of proanthocyanidins. However, the recognized method has some limitations, including the formation of anthocyanidins during purification process. In this study, grape seed extract was used instead of purified proanthocyanidins, and hydrophilic interaction chromatography and reverse-phase chromatography were employed for analysis. The established method showed higher accuracy and speed compared to the recognized method.

Summary: In this study, three different pectic polysaccharides were recovered from citrus canning processing water and their prebiotic potential and relationship between the RG-I domain and fermentation characteristics were evaluated. The results showed that the RG-I domain significantly influenced the fermentation characteristics of pectic polysaccharides, especially in terms of short-chain fatty acid production and modulation of gut microbiota. Pectins with a high proportion of the RG-I domain performed better in acetate, propionate, and butyrate production, and were degraded by Bacteroides, Phascolarctobacterium, and Bifidobacterium. This study highlights the benefits of pectic polysaccharides recovered from citrus processing and the role of the RG-I domain in their fermentation characteristics, providing a strategy for green production and value addition in food factories.

Summary: Different ratios of hesperetin (HT) were successfully grafted onto pectin molecules from basic water (PB) through free radical-induced reaction. The conjugates (PB-HT) were characterized by various analytical techniques, and the results showed successful grafting of HT onto pectin molecules, with PB-HT-0.5 having the highest HT content. Thermogravimetric analysis indicated that HT crystals exhibited good thermal stability and improved the thermal stability of the PB-HT conjugates. Furthermore, the PB-HT conjugates demonstrated good cytocompatibility and blood compatibility. This study presents a novel and efficient method for synthesizing hesperetin-grafted pectin conjugates with potential applications in functional foods.
