The invention discloses a preparation method and application of instant rice noodles suitable for people with hyperglycemia and people wanting to lose weight, and belongs to the technical field of
deep processing of agricultural products. The loss of active ingredients such as
flavones in crushing and
extrusion gelatinization processes is reduced by flexibly crushing through a semi-dry method andadding konjaku flour. Germinated tartary buckwheat,
white kidney bean extract, the konjaku flour,
mulberry leaf extract and the like are compounded to change the composition of
starch, so that the content of
resistant starch is remarkably increased, the content of rapidly
digestible starch is reduced, and thus a
starch digestion rate is favorably reduced. By adding the
white kidney bean extract and the
mulberry leaf extract, the activity of
amylase is remarkably inhibited, and
starch digestion is delayed. The germinated tartary buckwheat, the
white kidney bean extract, the konjaku flour and the
mulberry leaf extract are combined to achieve a synergistic interaction effect in the aspects of improving the content of
resistant starch, reducing the activity of
amylase and the like, the instantrice noodles prepared through the method are good in taste, smooth and chewy, the
digestion rate of starch in the rice noodles is low, a
glycemic index is remarkably lower than that of fresh wet polished rice noodles, and the product is suitable for people with hyperglycemia and people wanting to lose weight, and has a wide application prospect.
