Embodiment 1

[0041]Weigh 10.0g of potato starch and 1.0g of ellagic acid respectively, place them in the ceramic tank of the planetary ball mill, add auxiliary grinding balls of different sizes according to the mass ratio of the ball to the mixture close to 6:1, seal the ceramic tank, and install it in the ball mill , set the rotation speed to 500r / min, and run the ball mill; after the ball mill has been running for 10 hours, pick out the auxiliary grinding balls, take the crude product out of the ceramic tank, and weigh 9.65g. Wash twice with absolute ethanol, each time using 96.5 mL of ethanol, then perform suction filtration, dry the filter cake, weigh 9.23 g, and obtain the starch-ellagic acid inclusion complex. By measuring the content of ellagic acid in the complex, the content of ellagic acid was measured to be 22.0 mg / g; through the sustained release test, it was found that the maximum sustained release rate was about 40%; through the DPPH, ABTS, superoxide anion Determination of f...

Embodiment 2

[0043] Weigh 10.0g of potato starch and 1.0g of ellagic acid respectively, place them in the ceramic tank of the planetary ball mill, add auxiliary grinding balls of different sizes according to the mass ratio of the ball to the mixture close to 6:1, seal the ceramic tank, and install it in the ball mill , set the rotation speed to 700r / min, and run the ball mill; after the ball mill has been running for 20 hours, pick out the auxiliary grinding balls, take the crude product out of the ceramic tank, and weigh 9.25g. Wash twice with absolute ethanol, each time using 92.5 mL of ethanol, then perform suction filtration, dry the filter cake, weigh 9.18 g, and obtain the starch-ellagic acid inclusion complex. By measuring the content of ellagic acid in the complex, the content of ellagic acid was measured to be 20.30mg / g; through the sustained release test, it was found that the maximum sustained release rate was about 37%; through the DPPH, ABTS, superoxide anion Determination of ...

Embodiment 3

[0045] Weigh 10.0g of potato starch and 1.0g of ellagic acid respectively, place them in the ceramic tank of the planetary ball mill, add auxiliary grinding balls of different sizes according to the mass ratio of the ball to the mixture close to 6:1, seal the ceramic tank, and install it in the ball mill , set the rotation speed to 600r / min, and run the ball mill; after the ball mill has been running for 15 hours, pick out the auxiliary grinding balls, take the crude product out of the ceramic tank, and weigh 9.45g. Wash twice with absolute ethanol, each time using 94.5 mL of ethanol, then perform suction filtration, dry the filter cake, weigh 9.14 g, and obtain the starch-ellagic acid inclusion complex. By measuring the content of ellagic acid in the complex, the content of ellagic acid was measured to be 20.6mg / g; through the sustained release test, it was found that the maximum sustained release rate was about 39%; through the DPPH, ABTS, superoxide anion Determination of f...

Abstract

The invention discloses a preparation method of a starch-ellagic acid inclusion complex and application of the starch-ellagic acid inclusion complex to antioxidant food, and belongs to the technical field of preparation of antioxidant functional food. The preparation method comprises the following steps of putting potato starch and ellagic acid into a ball mill according to a certain mass ratio, carrying out ball-milling treatment for a preset time under the conditions of a certain ball-milling rotating speed and a certain ball-to-material ratio, washing with ethanol to remove unincluded parts, and performing drying and crushing to obtain the starch-ellagic acid inclusion complex. The inclusion complex has good slow release performance and good in-vitro anti-oxidation and free radical scavenging effects. The inclusion complex has the advantages of simple preparation process, low investment cost, easy acquisition of raw materials and green and environment-friendly effects of products, can be used for preparing cake, solid beverages and the like with antioxidant functions, and has wide application prospects.

Description

technical field [0001] The invention relates to a preparation method of a starch-ellagic acid inclusion complex and its application in anti-oxidation functional food, belonging to the field of food. Background technique [0002] With the development of society, problems such as electric radiation and environmental pollution are becoming more and more serious. These factors can cause the body to produce free radicals, and too many free radicals can cause serious oxidative damage to the body, thereby accelerating human aging and inducing cancer, etc. many diseases. Therefore, it is necessary to supplement appropriate antioxidants to remove excess free radicals in the body in time, so as to prevent diseases and delay aging. [0003] As a polyphenol compound, ellagic acid has a strong antioxidant effect, can react stably with hydrogen peroxide free radicals in the chain, can scavenge oxygen free radicals and hydroxyl free radicals, and has anti-cancer and anti-aging effects. E...
