Embodiment 1

[0032]Mix 20g of cornstarch and 2g of apigenin evenly, place them in the ball milling tank of the planetary ball mill, add zirconia balls according to the mass ratio of the balls to the mixture close to 2:1, and control the total volume of the balls and materials to be no less than 20% of the total volume of the ball milling tank. 1 / 3, no more than 2 / 3 of the total volume of the ball mill tank, run the ball mill at a speed of 700r / min; after the ball mill has been running for 30 hours, pick out the zirconia balls, and take the product obtained from the ball mill out of the ball mill tank; use 66mL Absolute ethanol is used to wash the apigenin attached to the surface of the ball-milled product; the washed product is suction-filtered, dried, and passed through a 100-mesh sieve to obtain a cornstarch-apigenin self-assembly. The embedding rate of apigenin in the corn starch-apigenin self-assembly is 29.91%; the content of apigenin is 30.05 mg / g. The digestibility of the self-assem...

Embodiment 2

[0034] Mix 20g of cornstarch and 3g of apigenin evenly, place them in the ball milling tank of the planetary ball mill, add zirconia balls according to the mass ratio of the balls to the mixture close to 2:1, and control the total volume of the balls and the material to not less than 1 / 2 of the total volume of the ball milling tank. 1 / 3, no more than 2 / 3 of the total volume of the ball mill tank, run the ball mill at a speed of 700r / min; after the ball mill has been running for 35 hours, pick out the zirconia balls, and take the product obtained from the ball mill out of the ball mill tank; use 69mL Absolute ethanol is used to wash the apigenin attached to the surface of the ball-milled product; the washed product is suction-filtered, dried, and passed through a 100-mesh sieve to obtain a cornstarch-apigenin self-assembly. The embedding rate of apigenin in the cornstarch-apigenin self-assembly is 32.17%; the content of apigenin is 48.30 mg / g. The digestibility of the self-asse...

Embodiment 3

[0036] Mix 20g of cornstarch and 4g of apigenin evenly, place them in the ball milling tank of the planetary ball mill, add zirconia balls according to the mass ratio of the balls to the mixture close to 2:1, and control the total volume of the balls and materials to be no less than 20% of the total volume of the ball milling tank. 1 / 3, no more than 2 / 3 of the total volume of the ball mill tank, run the ball mill at a speed of 700r / min; after the ball mill has been running for 40 hours, pick out the zirconia balls, and take the product obtained from the ball mill out of the ball mill tank; use 72mL Absolute ethanol is used to wash the apigenin attached to the surface of the ball-milled product; the washed product is suction-filtered, dried, and passed through a 100-mesh sieve to obtain a cornstarch-apigenin self-assembly. The embedding rate of apigenin in the corn starch-apigenin self-assembly was 35.71%; the content of apigenin was 71.51 mg / g. The digestibility of the self-as...

Abstract

The invention discloses a preparation method of a starch and apigenin self-assembly body and a purpose thereof in an aspect of starch digestion inhibition. The self-assembly body is prepared by uniformly mixing corn starch, potato starch and high-amylose corn starch with apigenin according to a certain mass ratio and then performing common ball milling treatment, ethanol washing, suction filtration, drying and sieving. The stability of a product is high; good digestion inhibition performance is realized; after the product is eaten, the fast rise of blood glucose cannot be easily caused; and agood effect is achieved on maintaining the stable state of postprandial blood sugar, so that the self-assembly body has huge application potentials in the fields of food and health care.

Description

technical field [0001] The invention belongs to the technical field of food nutrition and processing, and mainly relates to the application of a self-assembled body formed by starch and a certain amount of apigenin through a ball milling method in inhibiting digestion of starch. Background technique [0002] Starch is the main storage form of carbohydrates and consists of amylose and amylopectin. Amylose and amylopectin are two types of D-glucose polymers with different glycosidic linkages. Amylose is a glucose unit linked by α-(1,4) glycosidic bonds, and amylopectin is connected end to end by 95% α-(1,4) glycosidic bonds, with 5% α-(1, 6) The glycosidic bond is a branched glucose unit, therefore, starch can be regarded as a high polymer of glucose. After starch is ingested by the human body, it will be decomposed into glucose, causing a rapid rise in blood sugar after meals. The glycemic index is an important nutritional indicator of human health and is closely related to...
