Embodiment

[0009] Embodiment: A kind of production technology of extracting silkworm chrysalis oil, realizes according to following steps: (1), after drying to the silkworm chrysalis pulverization of water content less than 15%, pack in the extraction kettle; (2), directly use compressor to put food After the carbon dioxide is pressurized, it is sent into the extraction kettle through a surge tank (without any entrainer); (3), after the set pressure in the extraction kettle reaches 15Mpa-30MPa and the set temperature is 30°C-50°C, open the separation kettle Control the valve so that the carbon dioxide extracted from the silkworm chrysalis oil enters the separation kettle, and the pressure is reduced to 4Mpa ~ 6Mpa, and the temperature is 20°C ~ 40°C. At this time, the extracted product is separated from the carbon dioxide gas, so that the finished product is decomposed, and the carbon dioxide gas is circulated. use.

[0010] In the present invention, the carbon dioxide gas separated from...

example

[0011] Example: After drying silkworm chrysalis, a fresh by-product of the silk reeling factory, at a temperature of less than 60°C, dried silkworm chrysalis with a water content of less than 15% is obtained, which is then crushed into powder and extracted in an extraction kettle with carbon dioxide supercritical fluid. The carbon dioxide gas containing the extract is separated to obtain a light yellow oily substance rich in biologically active substances, and the separated carbon dioxide gas is purified and recycled. The conditions for carbon dioxide supercritical extraction are:

[0012] Extraction pressure 15MPa-30MPa;

[0013] Extraction temperature 30℃~50℃;

[0014] Separation pressure 4MPa-6MPa;

[0015] Separation temperature 20°C-40°C;

[0016] Extraction time 3-9 hours.

[0017] The net yield of extracted silkworm chrysalis oil is 20%-27%.

[0018] The extracted product can be provided to the pharmaceutical industry and health food production factory for direct u...

Abstract

This invention discloses a kind of production technique about the extraction of silkworm chrysalis oil, which is proceeded through such steps: (1) Disintegrate dried silkworm chrysalis powder and put it into a extraction kettle; (2) pressurize food-level carbon dioxide with compressor and deliver it to the extraction kettle by a pressure-stable tank; (3)After the setted pressur 15MPa-30MP and setted temperature 30deg C-50deg C are obtained, open control flap of the separating pot to make carbon dioxide, which has extracted silkworm chrysalis oil, enter into the extraction kettle. Then lower the pressure to 4MPa- 6Mpa, here the extracted substance separates from carbon dioxide gas, thereby the manufactured goods are resolved and carbon dioxide gas can be used cyclely. The product made through this production technique remains no organic solvent, and the biological active compounds in it won't be destroyed, at the same time, the recovery ratio of the product is high.

Description

technical field [0001] The invention relates to a production process of silkworm chrysalis oil. Background technique [0002] The development of silkworm chrysalis as a food and medicine resource is a new high-tech biological industry with broad market prospects. The main components of silkworm chrysalis are fat and protein. Silkworm chrysalis oil is rich in unsaturated fatty acids, among which linoleic acid, linolenic acid and other active ingredients can reduce serum cholesterol and improve liver function in patients with fatty liver and diabetes. "Compendium of Materia Medica" pointed out: silkworm chrysalis tastes salty and pungent, neutral in nature, and non-toxic. Human food can strengthen the body, and it can be used as medicine to treat multiple diseases. Modern medicine has proved that eating silkworm chrysalis often can regulate the body's physiological functions, prevent cardiovascular and cerebrovascular diseases, reduce blood lipids, liver cirrhosis, coronary ...
