Abstract:
Using jujube slag as material,the waterinsoluble dietary fiber was extracted from jujube slag with chemical method.The effect of concentration of sodium hydroxide,solid liquid ratio,extraction temperature and time on the yield of jujube dietary fiber were studied by single factor experiments and orthogonal experiment,and the extraction process was further optimized.The results showed that the optimum conditions were that the concentration of sodium hydroxide 5%,solid liquid ratio 1∶4 g/mL,extraction temperature 50℃ and extraction time 40 min.Under these conditions,dietary fiber yield reached 17.01%,and the production was light yellow,with no other peculiar smell.
