Abstract

The invention relates to the technical field of oil production and provides a method for extracting chrysalis oil from silkworm chrysalis by a supercritical fluid extraction technology. The method comprises the following steps of carrying out an extraction process on silkworm chrysalis by a supercritical CO2 fluid at an extraction temperature of 55 DEG C under extraction pressure of 25Mpa, carrying out separation of the extract obtained by the previous step at a separation temperature of 50 to 65 DEG C under separation pressure of 8 to 10Mpa, and collecting a separated liquid which is the chrysalis oil. The method improves an extraction rate of chrysalis oil and alpha-linolenic acid content of chrysalis oil. Azelaic semialdehyde is detected in the chrysalis oil obtained by the method for the first time. The method has a chrysalis oil extraction rate of 33.95% and the chrysalis oil extracted by the method has alpha-linolenic acid content of 67.911%. The chrysalis oil obtained by the method can be used for preparation of drugs and / or health products for diminishing inflammation, resisting allergy, reducing blood fat, reducing blood pressure, reducing blood sugar, resisting aging, preventing myocardial infarction and preventing cerebral infarction.

Description

technical field [0001] The invention relates to the technical field of oil production, in particular to a method for extracting silkworm chrysalis oil. Background technique [0002] α-linolenic acid is an essential fatty acid for the human body, which can be converted into docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are necessary for metabolism, and are the basic substances that constitute cell membranes and biological enzymes. It plays a decisive role in human health and can improve and prevent diseases such as hyperlipidemia, hyperglycemia and hypertension. α-linolenic acid cannot be synthesized in the human body and can only be ingested from food. At present, most of the products containing α-linolenic acid in the market are extracted and refined from perilla oil, seabuckthorn seed oil, linseed mustard oil, etc., but the extraction process is complicated, and the content of α-linolenic acid is not high. In recent years, silkworm chrysalis oil is of...
