“…In this study, the production of acetic acid, propionic acid and total SCFAs of F-IDF and F-SDF was significantly increased, compared with U-IDF and U-SDF, respectively, indicating that alkali oxidation + Aspergillus niger fermentation + cellulase hydrolysis treatment could significantly improve the fermentable properties of IDF and SDF and enhance SCFAs production. Previous research studies have reported that the treatment of dietary fiber could improve SCFA production from in vitro fermentation [44], which is consistent with this study. In addition, the ability of F-SDF to produce acetic acid, propionic acid and total SCFAs was the highest in all the samples, suggesting its potential prebiotic effects on the host's health.…”

Corn straw is one kind of agricultural by-product containing 70–80% insoluble dietary fiber (IDF). In order to develop corn straw dietary fiber, this study was conducted to increase soluble dietary fiber (SDF) yield and improve the structure, functional and prebiotic properties of IDF and SDF from corn straw treated by alkali oxidation treatment, enzymatic hydrolysis, microbial fermentation and the combination of these methods. The results demonstrated that the yield of SDF was significantly increased from 2.64% to 17.15% after corn straw was treated by alkali oxidation treatment + Aspergillus niger fermentation + cellulase hydrolysis, compared with untreated corn straw. The SDF extracted from corn straw treated by alkali oxidation treatment + Aspergillus niger fermentation + cellulase hydrolysis (F-SDF) exhibited a honeycomb structure, low crystallinity (11.97%), good antioxidant capacity and high capacities of water holding, water solubility and cholesterol absorption and promoted short-chain fatty acids production by chicken cecal microbial fermentation in vitro. F-SDF enhanced the antibacterial activity against Escherichia coli and Staphylococcus aureus proliferations of Lactobacillus plantarum when it was used as a substrate for Lactobacillus plantarum fermentation. It could be concluded that the combined treatments could increase SDF yield from corn straw and improve its functional and prebiotic properties.

This study aimed to investigate the anti‐obesity mechanisms of rice bran total dietary fiber (RDF), rice bran insoluble DF (RIDF), and rice bran soluble DF (RSDF) from defatted rice bran. RDF, RIDF, and RSDF exhibited excellent anti‐obesity effects, mainly reflected in lipid adsorption in vitro, reduction of body weight, inhibition of adipose tissue accumulation, improvement of dyslipidemia, and repair of histopathological damage. More importantly, the analysis of multi‐omics results revealed that the regulation of intestinal microbiota, amino acid metabolism, and lipid metabolism were the critical pathways for the anti‐obesity effects of RDF, RIDF, and RSDF. However, RIDF was involved in lipid metabolism through alanine, aspartate, and glutamate metabolism and exhibited a more favorable regulatory effect on gut microbiota. In contrast, RSDF impacted metabolic pathways dominated by tryptophan and cholesterol metabolism and excelled in immune and inflammatory amelioration. RIDF and RSDF together constitute RDF, with the latter integrating the tendencies of RIDF and RSDF in terms of intestinal microbiota and hepatic gene expression. However, RDF exhibited significant differences in metabolic regulation compared to RIDF and RSDF, particularly concerning tryptophan metabolism. These findings demonstrated that RIDF and RSDF have distinct mechanisms in obesity management, and that both contributed differently to the anti‐obesity effect of RDF. This study provides experimental evidence for the development of different types of DF from defatted rice bran as personalized anti‐obesity dietary supplements. It also offers new insights for future precision nutrition interventions involving DF.

Microplastics (MPs) have emerged as a significant food‐related risk factor, posing potential threats to human health through dietary intake and the food chain. This review comprehensively analyses the impact of MPs as a novel food safety risk factor on human health (in particular on the gastrointestinal route). Furthermore, we explore the potential mechanisms by which dietary fibers (DFs) may alleviate the health risks associated with MPs. The impact of DFs on human health is intricately linked to factors such as their size, concentration, and composition. We characterize current knowledge and highlight gaps. Although DFs may be a potential strategy to reduce the impact of MPs on organism health, more in‐depth studies are needed to determine their practical effects and application prospects. In particular, research on MPs that actively reduce intake in vivo remains relatively limited and needs to receive more attention from the scientific community.
