The overheating mosture in raw material instantly vapor vapor and explode.  Water molecules can expand 2000 times. Huge expansion pressure not only destroyed the external form of raw materials, but also pull off the internal molecular structure of materials, the insoluble long chain starch chopped into water-soluble short chains starch, dextrin and sugar. Therefore, reduces the insoluble substance in the puffed food, water-soluble substances increased.
