RS-3 fermentation adult
Twelve novel resistant starch type 3 substrates differing in crystal type (A/B), alpha-1,4 glucan chain length (degree of polymerization 14 - 76) and molecular weight distribution (1.08 - 2.11) were fermented in vitro using an inoculum of pooled faeces obtained from four healthy adults. A selection of substrates was also treated with pancreatin to remove an easily digestible fraction, prior to in vitro fermentation using the same pooled adult faecal inoculum.
