Abstract:
Taking carrot pomace as material,the volume of extract,alkali concentration,extracting time and extracting temperature were studied by using quadratic rotary combinational design,in order to optimize the extraction of insoluble dietary fiber (IDF) from carrot pomace.The results showed quadratic model was the best model to describe the relationship between the yield of IDF and the factors.R-squared adjusted value of the model was 0.9326.The optimized conditions for IDF extraction were 11% of alkali concentration at the amount of extract of 15 mL,extracting time of 5 h and extracting temperature of 38℃.The yield of IDF was 49.01%.The results of physical and chemical properties showed that the swelling capacity was 8.87 mL/g and water holding capacity was 3.97 g/g.
