Research of pullulanase treatment on promotive resistant starch content effects
The using of starches of rice, kudzu, mung bean and lotus as law material, putting some debranching enzyme in them, then we study the common law of promoting the resistant starch contents of the four starches. The experimental results indict that the variation curve of each factor is no significant change. The influence level of the factors is concentration of starch milk, cold storage temperature, the dose of pullulance, the enzymic time of pullulanase in turn. Then we can make the conclusion that the optimum process is the concentration of starch milk is 9%, temperature is(0～4) ℃, the pullulanase was added 5.75 ASPU/g starch for 90 min.
