Problems solved by technology

[0003] The traditional process consumes a large amount of organic reagents, complex operation, expensive equipment, large loss of reagents, and direct water extraction, which has the characteristics of low cost and simple extraction process
In the suction filtration process, the filter medium has low precision and belongs to dead-end filtration, the quality of the filtrate is unstable, more impurities will be brought in, and the yield is low

Embodiment Construction

[0021] specific implementation plan

[0022] now attached figure 1 The present invention will be further described in detail with specific embodiments.

[0023] Concrete embodiment manufacturing steps are as follows:

[0024] Such as figure 1 As shown, a high-efficiency anthocyanin extraction method, the specific steps include:

[0025] Step 1, crushing: the black beans are washed and put into crushing and leaching to obtain a leach solution containing black soybean dregs; the black soybean dregs are crushed and leached in water by wet crushing.

[0026] Step 2, coarse filtration: the leachate containing black soybean dregs is subjected to coarse filtration, and larger particles are removed to obtain a coarse leachate;

[0027] Step 3, fine filtration: Put the obtained coarse leachate into the ultrafiltration membrane for fine filtration treatment, remove the larger protein and other impurities in the middle of the leachate; coarsely extract the macromolecular protein and ...

Abstract

The invention provides an efficient anthocyanidin extraction method, comprising the steps of I, crushing; II, roughly filtering; III, finely filtering; IV, concentrating; V, extracting via a solvent; VI, drying by spraying; VII, adsorbing. Anthocyanidins extracted by efficient anthocyanidin extraction method are good in stability, extraction rate and purity of functional effective ingredients are high, and system service life is long; membrane stain resistance is high, reproducibility is good, and the method is available for providing high-treatment-throughput high-stability continuous automatic production for a long time.

Description

technical field [0001] The invention relates to the technical field of anthocyanin film treatment, in particular to a high-efficiency anthocyanin extraction method. Background technique [0002] Anthocyanin is a pure natural anti-aging nutritional supplement. Studies have shown that it is the most effective antioxidant found by humans today. Its antioxidant performance is fifty times higher than vitamin E and twenty times higher than vitamin C. It is 100% bioavailable to the human body and can be detected in the blood twenty minutes after ingestion. In Europe, anthocyanins are known as "oral skin cosmetics", especially blueberry anthocyanins, which nourish the skin, enhance skin immunity, and respond to various allergic symptoms. The discovery of black wolfberry has subverted the original blueberry is the fruit containing the king of anthocyanins. The anthocyanin contained in black wolfberry is several times or even ten times that of blueberries, and it can also maintain no...
