Abstract

The invention relates to papaya seed oil and an extraction method thereof. The extraction method comprises the following steps: drying the papaya seeds, pulverizing, adding an extraction solvent, stirring for extraction, oil-filtering, collecting the filtrate, concentrating by vacuum evaporation, and recycling the extraction solvent to obtain the papaya seed oil. The invention effectively solves the problems in the comprehensive utilization of the papaya seeds. The solvent method for extracting the papaya seed oil has the advantages of high extraction yield, good product quality, low production-equipment investment and simple technology, and is easy for industrial production.

Description

technical field [0001] The invention relates to a method for extracting tropical and subtropical fruit seed oil, in particular to a method for extracting papaya seed oil from papaya seeds by solvent method. Background technique [0002] Papaya seeds are a by-product of papaya processing enterprises, and many factories discard them as garbage, resulting in a great waste of resources. After analysis and determination, the oil content of papaya seeds reaches about 30%, and its composition is mainly monounsaturated fatty acid-oleic acid, and its content is as high as more than 70%. Oleic acid can maintain the balanced concentration of "high-density lipoprotein cholesterol" to ensure the body's demand for cholesterol; oleic acid can prevent atherosclerosis, regulate blood lipids, lower blood pressure, reduce blood viscosity, prevent the formation of thrombus, and protect the heart Avoid the harm of coronary heart disease and reduce the occurrence of cardiovascular diseases; olei...
