Problems solved by technology

[0003] However, because silkworm chrysalis has a special stench, it is unacceptable to directly use it as food. Most of the existing silkworm chrysalis oil deodorization methods are organic solvent extraction, and organic solvents will remain in the chrysa

Embodiment 1

[0019] Embodiment 1 The preparation of pupa oil of the present invention

[0020] Dried silkworm chrysalis is screened to remove dead silkworms, dead silkworms, bad pupae and other fiber impurities, and the coarse powder is crushed to 80-100 mesh, and then passed through CO 2 Supercritical extraction, 400L container pressure 25-30Mpa, temperature 35-40°C, separation pressure 5-7Mpa, separation temperature 30-34°C, CO 2 Flow 1.7m 3 / h, time 80 ~ 120min to separate crude silkworm chrysalis protein and silkworm chrysalis hair oil.

[0021] Take 100Kg of silkworm chrysalis crude oil, stir it in a 200ml reactor for 10min, take a sample and analyze the acid value, and neutralize it with 4-10% sodium hydroxide (food grade) solution at 40-90°C until the pH is 7±0.1, at 80°C Add about 10% of physical adsorbent activated carbon, stir for 40-90 minutes, and filter to obtain pupa oil, with a yield of 90%. The product indicators are shown in Table 1:

Embodiment 2

[0022] Embodiment 2 Preparation of pupa oil of the present invention

[0023] Dried silkworm chrysalis is screened to remove dead silkworms, dead silkworms, bad pupae and other fiber impurities, and the coarse powder is crushed to 80-100 mesh, and then passed through CO 2 Supercritical extraction, 400L container pressure 25-30Mpa, temperature 35-40°C, separation pressure 5-7Mpa, separation temperature 30-34°C, CO 2 Flow 1.5m 3 / h, time 80 ~ 120min to separate the crude silkworm chrysalis protein and silkworm chrysalis hair oil.

[0024] Take 200Kg of silkworm chrysalis hair oil, stir it in a 400ml reactor for 10min, take a sample and analyze the acid value, and neutralize it with 5-10% sodium hydroxide (food grade) solution at 40-90°C until the pH is 7±0.1, at 80°C Add about 5% each of physical adsorbent clay and activated carbon, stir for 40-90 minutes to settle, and centrifuge to obtain pupa oil. Centrifugation conditions: temperature 50-60°C, speed 4000-5000rmp, time 1-2 ...

Embodiment 3

[0025] Embodiment 3 Preparation of pupa oil of the present invention

[0026] Dried silkworm chrysalis is screened to remove dead silkworms, dead silkworms, bad pupae and other fiber impurities, and the coarse powder is crushed to 80-100 mesh, and then passed through CO 2 Supercritical extraction, 400L container pressure 24~30Mpa, temperature 30~35℃, separation pressure 4~8Mpa, separation temperature 25~33℃, CO 2 Flow 1.3m 3 / h, time 100-150min to separate crude silkworm chrysalis protein and silkworm chrysalis hair oil.

[0027] Take 100Kg of silkworm chrysalis crude oil, stir it in a 200ml reactor for 10min, take a sample and analyze the acid value, and neutralize it with 4-10% sodium hydroxide (food grade) solution at 40-90°C until the pH is 7±0.1, at 80°C About 7% of physical adsorbent clay and activated carbon were added, stirred for 40-90min, and pupa oil was obtained by suction filtration, with a yield of 90%. Product indicators are shown in Table 1.

Abstract

The method for preparing silkworm cocoon oil includes the following steps: pulverizing silkworm cocoon, utilizing CO2 supercritical extraction to separate out crude oil, making the crude oil undergo the processes of physical adsorption and separation so as to obtain the invented silkworm cocoon oil with high unsaturated fatty acid content, low palmitic acid content and good taste. Besides, it also has the health-care functions of softening blood vessel, reducing blood pressure, reducing blood-lipid, reducing blood sugar and preventing arteriosclerosis and thrombosis, etc.

Description

technical field [0001] The invention relates to silkworm chrysalis oil and a production method thereof, belonging to the field of health care products. Background technique [0002] Silkworm chrysalis is a by-product of the production process of the silk industry, and has attracted people's attention as a source of oil. Silkworm chrysalis contains about 30% of pupa oil. It contains polyunsaturated fatty acids (including linoleic acid and linolenic acid) that are necessary for the human body but cannot be synthesized by themselves. Polyunsaturated fatty acids are called "vascular scavenger" by the medical field; linolenic acid and linoleic acid have good curative effects on high cholesterol and fatty liver, diabetic patients and malnourished patients. The functions of pupa oil include: adjusting fat metabolism disorders, effectively eliminating cholesterol in the body; softening blood vessels, lowering blood pressure, blood lipids, preventing arteriosclerosis and thrombus; ...
