Abstract

The invention discloses a method of preparing purslane polyunsaturated fatty acids from purslane residues. The method comprises the following steps: selecting the purslane residues; raising the extraction pressure of subcritical fluid extraction by 0.8MPa and raising the extraction temperature by 40 DEG C, and extracting for 150 minutes; saponifying and hydrolyzing to prepare a fatty acid mixed before enrichment; heating and stirring urea and anhydrous ethanol for reflux at 60 DEG C in a ratio m / m of urea and fatty acid mixed before enrichment of 1 to 1 and in a ratio m / v of fatty acid mixed before enrichment and ethanol of 1 to 16; after dissolving urea and uniformly mixing with the fatty acid mixed before enrichment, heating and stirring for reflux for 20 minutes; cooling to room temperature; crystallizing for 24 hours at 4 DEG C; filtering to obtain the fatty acid mixed after enrichment. Verified by diabetic rat test, the prepared purslane polyunsaturated fatty acid microcapsule and soft capsule can effectively reduce the levels of blood glucose and insulin and have wide application value and prospect in preparing foods or medicines for preventing and treating diabetes.

Description

technical field [0001] The invention relates to the technical field of extraction and preparation of polyunsaturated fatty acids. Specifically, the invention relates to the technical field of preparing purslane polyunsaturated fatty acid from purslane residue. Background technique [0002] Polyunsaturated fatty acids are an indispensable nutrient for the growth and development of humans or animals, mainly including linoleic acid, linolenic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid ( DHA), among which linoleic acid and α-linolenic acid cannot be synthesized in the human body and can only be obtained from food intake, so they are called essential fatty acids for the human body. It has many functions, such as lowering blood fat, lowering blood pressure, antithrombotic, improving immunity, preventing and regulating cardiovascular diseases, etc. It is widely used in food, medical care, etc. for its unique nutritional components and medicinal value. in various f...
