Research of extracting dietary fiber from Laminaria Japonica by using enzyme and chemical combination methods
The dietary fiber is extracted from in the extraction brown alga syrup Laminaria Japonica dregs, the optimum technological conditions for the extracting dietary fiber from Laminaria Japonica have been obtained by using enzyme and chemical combination methods, It is 80 ~100 item, the liquid -solid compares 1 ∶50, enzymolysis time 4 h, the enzyme joins measures 60 g/kg. Again using 1% sodium carbonate solution, the liquid -solid compares 1 ∶30, 55 ℃ processes 1.5 h. The results show that the yield of dietary fiber from Laminaria Japonica is 22.9%.
