Biological Extraction Process of Sunflower Meal

Abstract

The invention relates to a sunflower seed meal biological extraction method. The sunflower seed meal biological extraction method comprises four steps: 1, protolysate extraction; 2, chlorogenic acid extraction; 3, polysaccharide extraction; and 4, environmental protection processing. Compared with the prior art, the sunflower seed meal biological extraction method possesses following advantages: 1, synchronous extraction of protolysate, chlorogenic acid, and polysaccharides is realized, efficiency is high, resources are saved, alkaline water is adopted to replace ethanol for extraction, low yield is increased, and flammable and combustible hidden troubles are avoided; 2, enzymatic browning and non-enzymatic browning of chlorogenic acid are inhibited, processing steps where loss of chlorogenic acid is easily caused are avoided, and chlorogenic acid purifying is improved; and 3, after processing, zero waste water discharge is realized, only solid waste is discharged, environment requirements are satisfied, and the sunflower seed meal biological extraction method is friendly to the environment.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a biological extraction process of sunflower seed meal. Background technique [0002] Sunflower is divided into edible sunflower and oil sunflower. Sunflower meal is the by-product of oil sunflower peeling and oil extraction. It should be a good feed because it is rich in protein, but because it contains "toxin" chlorogenic acid, it is not only easy to oxidize and become Dark green or even dark brown, and the resulting o-quinone is easy to combine with protein, making protein an indigestible component. [0003] The essence of chlorogenic acid is an organic substance with high biological activity. It has anti-oxidation, anti-tumor, anti-AIDS, anti-bacterial, anti-virus, anti-inflammatory, anti-aging, enhances white blood cells, protects fetus, nourishes kidney, promotes gallbladder, etc. As a raw material for medicine, health care products and cosmetics, it is recognized as "plant go...

AI Technical Summary

Problems solved by technology

[0015] (1) There are flammable and explosive hazards in the large-scale use of ethanol, and 20% of ethanol is difficult to recycle;

[0016] (2), Isoelectric point + thermal denaturation to remove protein, extraction and removal of polysaccharides, the loss of chlorogenic acid is more;

[0017] (3) There is a lack of measures to inhibit the browning of chlorogenic acid, and even heating in some processes promotes oxidation;

[0018] (4), single extraction of chlorogenic acid, low resource utilization rate, difficult to meet the waste water discharge standards, polluting the environment

[0027] (1) Acidic hot water extraction, although the solvent cost is relatively low, but the low solubility affects the yield;

[0028] (2) There is a lack of measures to inhibit the browning of chlorogenic acid, and even heating in some processes promotes oxidation;

[0030] (4), single extraction of chlorogenic acid, low resource utilization rate, difficult to meet the waste water discharge standards, polluting the environment
