Mumia protein and its production process

Abstract

The silkworm chrysalis protein preparing process includes the following steps: crushing silkworm chrysalis; supercritical CO2 extraction at 30-40 deg.c temperature and 20-35 MPa pressure inside a 400 L container; separation at 25-34 deg.c temperature, 4-8 MPa pressure and 1-2 cu m / hr CO2 flow rate for 80-150 min to obtain coarse protein; grinding, sieving, and airflow crushing to obtain the silkworm chrysalis protein product. The preparation process has advanced supercritical extraction and low temperature airflow crushing, and the prepared silkworm chrysalis protein has no bad smell, high safety, high nutrient value, high bioavailability and obvious effect of remitting fatigue.

Description

technical field [0001] The invention relates to protein extracted from animals, in particular to silkworm chrysalis protein. Background technique [0002] Protein occupies an extremely important position in human nutrition, and has been widely used in food, medicine, cosmetics and other fields. The United Nations Food and Oils Organization (PFO) and the World Health Organization (WHO) have proposed an ideal protein standard that the content of essential amino acids should be above 40%. Therefore, the production of edible and medicinal high-quality proteins that meet this standard has always been a must for the majority of researchers and producers. direction of effort. [0003] Silkworm chrysalis is a by-product in the production process of the silk industry, and it has attracted widespread attention as a source of protein. Silkworm chrysalis contains about 57% of pupa protein, about 30% of pupa oil, and about 70% of rich polyunsaturated fatty acid in pupa oil. Because si...

Problems solved by technology

Because silkworm chrysalis has a special fishy smell, it is unacceptable to be directly used as food. At present, there is no silkworm chrysalis food that solves the problem of fishy smell and is suitable for consumers.

[0004] CN1087346, CN1091904, CN16101511 deodorization method can be divided into two classes, and a class is to carry out deodorization to albumen slurry with oxidizing agent (hydrogen peroxide, chlorine, ozone), and after deodorizing, albumen has the problem of reducing odor, in addition, these oxidizing agents are difficult to The deodorization process of the above-mentioned patent has complex process, long process, large energy consumption, and large pollution of three wastes, so it is not suitable for industrial production.

Therefore, at present, silkworm chrysalis is still used as primary feed, and it has little practical value for livestock, poultry, and fish. Not only is the resource utilization low, but also the meat of livestock, poultry, and fish raised by silkworm chrysalis has pupae smell, which affects the quality of the meat.
