Effects of Three Processed Products from Corn Bran on Gut Microbiota in D-Galactose Induced Aging Mice
Corn bran is a byproduct of corn starch processing and is rich in dietary fiber.In this experiment,a senescence mouse model was established using D-lactose to investigate the effects of refined corn bran(RCB),hydrolysate of acid(HOA)from RCB,and the eluate of HOA through XAD-2 macroporous resin(XE)on various aspects of the mouse gut microbiota,including richness and diversity.The results showed that all three treatment products could increase microbial diversity and the abundance of the Lactobacillales order and Lactobacillaceae family compared to the aging model group.The XE group could enhance microbial abundance.The RCB and HOA groups could reduce the quantity of Firmicutes and increase the quantity of Bacteroidetes,thereby lowering the Firmicutes/Bacteroidetes(F/B)ratio.RCB and XE could enhance the anti-aging,cellular activity,and excretory capacity of mouse gut microbiota,with XE showing better effects.The research results provide a theoretical basis for the improvement of gut microbiota and other diseases in the aging population through the treatment of corn bran derivatives.
