Abstract

Highlights: Sugarcane polyphenol/fiber mix enhanced the availability of polyphenols to colon. Sugarcane polyphenol/fiber mix increases SCFAs production during fecal fermentation. Sugarcane polyphenol/fiber mix modulates and improves the fecal microbiota profile. Abstract: This study aimed to examine the effects of sugarcane polyphenol and fiber (Phytolin + Fiber) on gut microbiota, short-chain fatty acids (SCFAs) production and phenolic metabolites production using in vitro digestion and fermentation model. Microbial profiling by 16S rRNA sequencing was used to analyze the pig faecal microbiota profile. SCFAs were identified and quantified by GC-FID, and phenolic metabolites were characterized by LC-ESI-QTOF-MS/MS. The results showed that Phytolin + Fiber exert synergistic effects on the pig gut microbiota by increasing the relative abundances of Lactobacillus and Catenibacterium, and decreasing the relative abundances of Mogibacterium, Dialister, and Escherichia-Shigella . Phytolin + Fiber also significantly increased the total SCFAs production, particularly the propionic and butyric acids. Production of phenolic metabolites related to major polyphenols in Phytolin were tentatively identified. These results suggest that Phytolin + Fiber could be beneficial to human colon health given the similarities between pig and human intestine in terms of physiology and microbiome.
