Problems solved by technology

Among them, storage under conditions such as avoiding light, sealing, and low temperature can improve the stability of blueberry anthocyanins, but it also limits the application range of blueberry anthocyanins; due to the instability of blueberry anthocyanins, it is difficult to separate Extract high-purity blueberry anthocyanins, and there are certain difficulties in chemically synthesizing blueberry anthocyanins; co-pigments can be flavonoids, alkaloids, organic acids, polysaccharides, etc., but the addition of co-pigments also affects blueberry to a certain extent. The stability of anthocyanin itself

Embodiment 1

[0026] A: Pulverize the attapulgite, pass it through a 200-mesh sieve, soak it with water, squeeze it against the roller three times, add deionized water to make a slurry, beat at 10,000 rpm for 30 minutes to disperse the attapulgite, and centrifuge at 1,500 rpm for 15 minutes. Take the upper layer suspension, continue to centrifuge the upper layer suspension at 3000 rpm for 30 min to obtain a paste, put it into an electric blast drying oven and dry it into a powder for later use.

[0027] B: Mix 0.5g of the attapulgite obtained in step A (with a particle size of 70µm) and 1g of blueberry anthocyanin evenly, add 0.6ml of ultrapure water and grind until the water is completely evaporated (about 15 minutes) to obtain blueberry anthocyanin Plain-attapulgite mixture.

Embodiment 2

[0029] A: Pulverize the attapulgite, pass it through a 200-mesh sieve, soak it with water, squeeze it against the roller three times, add deionized water to make a slurry, beat at 10,000 rpm for 30 minutes to disperse the attapulgite, and centrifuge at 1,500 rpm for 15 minutes. Take the upper layer suspension, continue to centrifuge the upper layer suspension at 3000 rpm for 30 min to obtain a paste, put it into an electric blast drying oven and dry it into a powder for later use.

[0030] B: Mix 1g of the attapulgite obtained in step A (with a particle size of 70µm) and 1g of blueberry anthocyanin evenly, add 0.8ml of ultrapure water and grind until the water is completely evaporated (about 15 minutes) to obtain blueberry anthocyanin - Attapulgite mix.

Embodiment 3

[0032] A: Pulverize the attapulgite, pass it through a 200-mesh sieve, soak it with water, squeeze it against the roller three times, add deionized water to make a slurry, beat at 10,000 rpm for 30 minutes to disperse the attapulgite, and centrifuge at 1,500 rpm for 15 minutes. Take the upper layer suspension, continue to centrifuge the upper layer suspension at 3000 rpm for 30 min to obtain a paste, put it into an electric blast drying oven and dry it into a powder for later use.

[0033] B: Take 2g of the attapulgite obtained in step A (particle size is 70µm) and mix evenly with 1g of blueberry anthocyanin, add 1.2ml of ultra-pure water and grind until the water is completely evaporated (about 15 minutes) to obtain blueberry anthocyanin - Attapulgite mix.

Abstract

The invention discloses a method for improving stability of blueberry anthocyanin through attapulgite. The method is characterized in that attapulgite is promoted to disperse through high-speed pulping, the specific surface area of attapulgite is increased, and anthocyanin is sufficiently combined with the attapulgite through wet-process grinding, so that an anthocyanin-attapulgite mixture is obtained. The method is simple to operate, is low in cost, greatly prevented the anthocyanin from being damaged, improves the stability and the anti-oxidization activity of blueberry anthocyanin, and has relatively good application value and a relatively good development prospect.

Description

technical field [0001] The invention relates to a method for improving the stability of blueberry anthocyanins, in particular to a method for improving the stability of blueberry anthocyanins by utilizing the adsorption performance of attapulgite. technical background [0002] As a natural food coloring, blueberry anthocyanin is safe, non-toxic, rich in resources, and has certain pharmacological effects and nutritional value. It has great application potential in medicine, food, cosmetics, etc. In addition, anthocyanins are the most effective natural free radical scavenger known so far, it can remove excessive free radicals in the body, and treat a series of diseases caused by excessive free radicals, such as inflammatory diseases, cardiovascular diseases and Diseases related to aging have the effect of prevention and improvement. However, from the perspective of chemical structure, anthocyanins have the characteristic of lacking one electron, and are easily attacked by act...
