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.

Embodiment 1

[0019] Example 1 Preparation of silkworm pupa protein of the present invention

[0020] Take silkworm pupae, sieve out dead silkworms, dead silkworms, bad pupas and other fiber impurities, crush them, add 10 times distilled water, neutralize with 5% w / w pharmaceutical grade hydrochloric acid to pH=7±1, centrifuge and spin dry at 50 Dry at ~70°C until the moisture content is less than 5%. Crush to 80-100 mesh powder, perform supercritical extraction in a 400L container, pressure 24-30Mpa, temperature 30-35℃, separation pressure 4-8Mpa; separation conditions: temperature 25-33℃, CO 2 Flow 1.3m 3 / h, time 100~150min, separate crude pupa protein and silkworm pupa hair oil.

[0021] The pupa protein is ground and sieved, and the 120 mesh fine silkworm pupa protein is taken (50% of the total protein is obtained), under the conditions of pressure 0.8~0.9Mpa, temperature -80~-90℃, air flow rate 670~700m / s, Carry out ultra-fine jet pulverization and sieving to obtain ultra-fine silkworm pu...

Embodiment 2

[0023] Example 2 Preparation of silkworm pupa protein of the present invention

[0024] Dry silkworm pupa sieve to remove dead silkworms, rigid silkworms, bad pupas and other fiber impurities, crush the coarse powder to 100 mesh, and then pass CO 2 Supercritical extraction, in a 400L container, pressure 25-30Mpa, temperature 35-40℃, separation pressure 5-7Mpa, separation temperature 30-34℃, CO 2 Flow 1.5m 3 / h, time 80~120min to separate the crude silkworm pupa protein and silkworm pupa hair oil. Under the conditions of pressure 0.9~1Mpa, -90~-100℃ and air flow rate of 670~700m / s, carry out ultrafine air jet pulverization and sieving to obtain ultrafine silkworm pupa protein that has passed through a 320 mesh sieve.

[0025] The obtained silkworm pupa protein quality index: the appearance is off-white, the protein content is 78-82% w / w, the fat content is less than 2% w / w, and the water content is less than 3% w / w.

Embodiment 3

[0026] Example 3 Preparation of protein food of the present invention

[0027] Take 100Kg of the ultra-fine silkworm pupa protein powder prepared in Example 1, add 8.2Kg of edible adhesive, 2Kg of disintegrant, 2Kg of release agent, and 9.5Kg of edible correctives (orange, orange, strawberry) in vigorous stirring. It is granulated, compressed, dried and packaged to produce a protein nutritional food with 12 grains per plate and 500mg per grain. Each grain contains 310mg protein, 7.75mg fat, 112.5mg auxiliary materials, and 77.5mg carbohydrate and fiber.

[0028] The present invention will be described in further detail below through a taste comparison test, but it should not be construed as a limitation of the present invention. All modifications, substitutions and alterations made based on the above technical ideas belong to the present invention.

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 an animal extract protein, in particular to a silkworm pupa 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 Oil Organization (PFO) and the World Health Organization (WHO) have proposed that the ideal protein standard is an essential amino acid content of more than 40%. Therefore, the production of high-quality edible and medicinal protein that meets this standard has been the majority of researchers and producers. The direction of the effort. [0003] Silkworm pupa is a by-product in the production process of the silk industry. It has attracted widespread attention as a source of protein. Silkworm pupa contains about 57% pupa protein, about 30% pupa oil, and about 70% rich polyunsaturated fatty acid in pupa oil. It has been used in the preparation of fortified foods and food ...
