Shinyleaf yellowhorn oil extraction method

Abstract

The invention belongs to the field of food processing and relates to a shinyleaf yellowhorn oil extraction method. The extraction method comprises the following steps: picking shinyleaf yellowhorn nuts, crushing, carrying out enzyme deactivation, carrying out ultrasonic pretreatment, adding pectinase, cellulase and an accelerator, carrying out enzymolysis, and carrying out centrifugation, thereby obtaining shinyleaf yellowhorn oil, wherein the pectinase accelerator is (2,4,6-trihydroxyphenyl)-4-(4-hydroxyphenyl)pyrazole. A preparation method comprises the following steps: dissolving genistein into ethanol, then, subjecting oil-bath heating together with hydrazine hydrate, carrying out reflux reaction, and then, cooling to room temperature; after a product is cooled, adjusting the pH value to generate precipitates; re-crystallizing the precipitates, and drying so as to obtain products. The shinyleaf yellowhorn oil extraction method provided by the invention has the advantages that the defects are overcome, the process is simple, the types of equipment are few, the operation is easy, the oil yield is high, the quality of the oil is good, the process is simple and safe, the oil preparation period is short, the cost is low, and shinyleaf yellowhorn protein or shinyleaf yellowhorn protein peptide can be prepared simultaneously.

Description

technical field [0001] The invention belongs to the field of agricultural product processing and relates to a method for extracting xanthania sorbifolium oil. Background technique [0002] Xantho sorbifolium belongs to Sapindaceae Xanthophyllum genus, also known as sorbifolia, radix sorbifolium, etc. It is a unique and precious woody tree species in my country. It is not only a nutritious and delicious fruit and a famous woody oil tree species, but also an important excellent water and soil conservation tree species that can improve the ecological environment and green the country. [0003] Xingguan fruit contains a lot of oil, the seed oil content rate is 30.4%, the seed kernel is rich in nutrition, the oil content rate is 55% ~ 66%, the unsaturated fatty acid content in its oil is as high as 94%, of which linoleic acid accounts for 36.9%, oleic acid It accounts for 57.2%; and contains 19 kinds of amino acids needed by the human body, various trace elements such as potassi...

Problems solved by technology

The traditional pressing process is simple to operate and has strong adaptability, but the high temperature above 200°C during the pressing process has caused great damage to other important nutrients such as unsaturated fatty acids and vitamin K in the oil, and also led to protein denaturation, etc. , the cake can only be used as animal feed, etc.; compared with the traditional pressing method, the extraction method is a relatively advanced oil production method, which has low labor intensity and higher production efficiency, but the organic solvent used for oil extraction It will overflow and volatilize, which will have a great adverse effect on the human body and the environment. Problems such as solvent residues and oil quality degradation have limited its development as edible oil and health care oil to a certain extent.
