Physicochemical properties and intestinal protective effect of ultra-micro ground insoluble dietary fibre from carrot pomace.

摘要: Carrot pomace is an abundant, but underutilized, byproduct from the juice industry. In this study, insoluble dietary fiber carrot was treated using ultra-microgrinding process, and resulting changes in its physicochemical properties intestinal protective effect against heavy metal damage were examined. The SEM fluorescence microscopy results showed that grinding process could significantly decrease particle size of fibre increase Brunauer-Emmett-Teller surface area 0.374 to 1.835 m(2) g(-1). Correspondingly, water-holding capacity, swelling oil-holding capacity increased by 62.09%, 49.25% 45.45%, respectively. glucose-, nitrite-, lead ion-adsorbing abilities also improved compared with raw samples. addition, apoptosis assessment AO/EB revealed ground effectively protect Caco-2 cells ion damage. MTT assay has no toxicity for at a concentration 10.0 mg L(-1). findings study highlighted potential produce high added-value ingredient residues.
