Production method of non-denatured pure sericin stock solution

Abstract

The invention discloses a production method of a non-denatured pure sericin stock solution. By utilizing the production method, the pure sericin stock solution is produced by evading sericin denatured conditions. The production method is simple, low in cost and suitable for production of nutritious foods, health care products and products in other fields.

Description

technical field [0001] The invention mainly relates to the field of production, in particular to a production method of non-denatured pure sericin stock solution. Background technique [0002] Sericin protein is a soluble globulin, which is easily absorbed by the human body; it is rich in 18 kinds of essential amino acids and polycarboxylates, a natural moisturizing ingredient, with strong water retention, moisturizing, anti-wrinkle, and whitening effects; it is compatible with copper, mercury, etc. Heavy metals are easy to form chelates, inhibit tyrosinase and other activities, contain functional groups to scavenge free radicals, have low digestibility, play an antioxidant role, maintain food safety, and reduce the activity of cancerous substances in the digestive system. Therefore, sericin has many unique functions and great market potential in the utilization of functional materials in nutritional food, medical care products and other fields.

Problems solved by technology

Although it can be used as waste, there are many disadvantages: ① Ordinary silkworm cocoons for silk reeling have to go through the first drying at 90°C, the second drying at 110°C, the cocoon cooking at 95°C, and the silk reeling at 85°C. Recovery of sericin protein from the waste liquid, denaturation of sericin protein caused by unavoidable high temperature

②Ordinary silkworm cocoon cocoon shell itself only contains about 25% sericin protein, and it is recovered from a large amount of silk reeling wastewater, which has low recovery efficiency and high cost; It takes a long time, the process is complicated, and it is difficult to remove the impurities mixed in, the spoilage and chemical residues involved in reeling in the recovery operation, and the purity of the recovered sericin protein is low

From the perspective of cost performance, it is not worth it; from the perspective of safety, the application in the fields of makeup, health care and medicine directly related to the human body not only does not have sufficient quality assurance, but may also have relatively large hidden dangers
