The invention provides a slowly-digestible hulless
oat biscuit and a preparation method thereof, and relates to the technical field of
food processing. Specifically, the slowly digestible hulless oat biscuits comprise the following materials in parts by weight: 30-50 parts of hulless oat flour, 15-25 parts of sweet potato
powder, 10 parts of
bran powder, 5-8 parts of oat flour, 9-12 parts of
corn flour, 15-20 parts of fruit and vegetable juice, 10 parts of
fiber powder, 0.3-0.6 part of flaxseed gum, 0.2 part of
sodium bicarbonate and 0.1 part of beta-
cyclodextrin. According to the slow
digestion type hulless
oat biscuit, the
pineapple juice and the
papaya juice are used for adjusting the taste and inhibiting the
enzyme activity, the
citric acid and the cress juice are used for adjusting the pH value, the
Maillard reaction is inhibited, the generation of
antioxidant components is promoted, minerals are chelated, and the absorption is improved;
bagasse and the like are fermented to extract
cellulose,
digestion is delayed by virtue of a'wrapping effect 'and a water absorption characteristic of a film, and beta-
glucan of hulless oat is combined to synergistically block
enzyme activity, so that multi-
vitamin health values of
sugar control,
oxidation resistance,
iron supplement and taste improvement are realized.
