Problems solved by technology

[0008] In summary, in the prior art, the extraction of Lycium barbarum polysaccharides, polypeptides, and Lycium barbarum is often carried out using Lycium barbarum as the starting raw material. During the extraction process, interference from other impurities will inevitably be received, resulting in a decline in the extraction rate and extraction purity. In the process of extracting effective substances from wolfberry as raw material, a lot of waste of raw material residues is often caused

[0047] Experimental example 1 Determination method of Lycium barbarum polysaccharide, Lycium barbarum, Lycium barbarum polypeptide

[0048] In the present invention, the determination method of Lycium barbarum polysaccharide is as follows: the determination of polysaccharide content in the sample refers to the SN / T4260-2015 method; the method of Lycium barbarum is: the determination of Lycium barbarum content in the sample is determined according to the established HPLC method; the method of Lycium barbarum polypeptide For: determined by using graphite digestion-semi-automatic nitrogen determination method.

[0049] 1. Determination of Lycium barbarum polysaccharides: using the method for the determination of reducing sugar content. Prepare a buffer solution, and the solution formula is to add 13.4 g of potassium sodium tartrate, 3,5-dinitrosalicylic acid, 1.8 g of sodium hydroxide, and 0.7 g of phenol per 100 mL of water. Use the glucose standard to draw a standard curve, ac...

Abstract

The invention discloses wolfberry polysaccharide, wolfberry red pigment, wolfberry polypeptide and a preparation method thereof which are simultaneously separated and prepared, and belongs to the technical field of wolfberry deep processing. In the present invention, Lycium barbarum is used as a raw material, and Lycium barbarum polysaccharide is obtained by soaking in water and extracted with ethanol. At the same time, the prepared Lycium barbarum residue is further added with an organic solvent for extraction to obtain Lycium barbarum red pigment, and the residue obtained in the previous step is continuously used by adding water and probiotics. , the polypeptide is prepared by microbial fermentation. In order to solve the problems of raw material waste and the like, the present invention maximizes the utilization value of Lycium barbarum. By using Lycium barbarum as raw material, Lycium barbarum polysaccharide, Lycium barbarum polysaccharide, Lycium barbarum polypeptide products are successively obtained at one time, and at the same time, Lycium barbarum polysaccharide, Lycium barbarum polysaccharide, Lycium barbarum The high-efficiency synergy of the continuous extraction of polypeptides not only improves the extraction efficiency and purity of each, but also effectively avoids the interference of other components on the extraction of the target components during the extraction process, and can be widely used in industrial production.

Description

technical field [0001] The invention belongs to the technical field of deep processing of wolfberry, and in particular relates to a synchronous separation and preparation of wolfberry polysaccharide, wolfberry red pigment, wolfberry polypeptide and a preparation method thereof. Background technique [0002] Lycium barbarum is a plant in the family Solanaceae. Lycium barbarum fruit is a traditional medicine and food homologous medicinal material in China. Lycium barbarum has a long history of consumption in my country. The "Dictionary of Chinese Medicine" records that wolfberry fruit has the effects of nourishing the liver and kidney, benefiting energy and improving eyesight. Modern biological research shows that wolfberry has various biological activities such as anti-oxidation, blood fat reduction, anti-aging, liver protection, etc. With people's attention to health, the consumption of wolfberry is increasing year by year. In order to meet the needs of different groups of pe...
