The invention discloses a preparation method of low-GI whole-grain furnace fruits rich in dietary fibers, and the preparation method of the low-GI whole-grain furnace fruits rich in dietary fibers comprises the following steps: step 1, extracting low-GI whole-grain
starch; step 2, treating the compound
powder with
pullulanase; and step 3, preparing the whole-grain furnace fruits. On the premise of ensuring the taste, the blood glucose generation index of the traditional old-fashioned oven fruit is reduced, and the food selection of
sugar-controlled people is enriched; meanwhile, multiple cereals are compounded, on the premise of low GI, the product is richer in nutritional value, rich in dietary fibers and
flavonoid substances, and beneficial to promoting intestinal tract movement and maintaining heart and
cerebral vessel health; the GI value is reduced through
pullulanase treatment, the specificity is higher, the purpose of reducing the GI value of a product can be better achieved, the method is low in investment,
environmentally friendly and capable of specifically acting on carbohydrates in food, the structure of the carbohydrates is changed through
hydrolysis, and therefore the GI value of the food is effectively reduced.
