Persimmon by-products, rich in fibre, promote beneficial gut bacteria

. The effect of phenolic molecules on the fermentative properties of persimmon substrates was also investigated. Faecal fermentation of soluble persimmon fractions led to higher production of indole-3-propionic acid compared to insoluble fractions. These findings underscore the potential health benefits of soluble fibre-rich persimmon by-products. Results presented here highlight the potential applications of persimmon by-products to formulate prebiotic ingredients that selectively stimulate the growth of beneficial gut commensals including next-generation probiotics.
