Ultrasonic-assisted rubber seed oil extraction method

Abstract

The invention discloses an ultrasonic-assisted rubber seed oil extraction method which comprises the following steps: step one, preparation of rubber seed cake raw materials; step two, preparation of rubber seed crude oil; step three, acidizing: the rubber seed oil is subjected to acidizing, and acidized rubber seed oil is obtained; step four, first enzymolysis, first rubber seed oil is prepared; step five, second enzymolysis, second rubber seed oil is obtained; step six, third enzymolysis, third rubber seed oil is obtained; step seven, vacuum drying: the third rubber seed oil is subjected to vacuum drying treatment, and the finished product rubber seed oil is obtained. According to the ultrasonic-assisted rubber seed oil extraction method, the phospholipid content in the rubber seed oil ranges from 5.28 mg / Kg to 9.42 mg / Kg, the rubber seed oil is safe and environment-friendly, the preparation is convenient, and the oil quality is good.

Description

technical field

[0001] The invention relates to the technical field of rubber seed oil, in particular to a method for ultrasonically assisted extraction of rubber seed oil. Background technique

[0002] Rubber seed is the seed of the capsule of Hevea brasiliensis, an arbor tree in the Euphorbiaceae family. It is oval, brown with silver-gray markings, and consists of a seed shell and a kernel. The kernel is covered with a soft film layer. It is a kind of to-be-developed Oil of tropical woody plants. The oil content of rubber seed kernels is as high as 50% / (dry basis), and the unsaturated fatty acid content in the oil is about 84% (including 25% oleic acid, 35% linoleic acid, and 24% linolenic acid), which are especially necessary for the human body and cannot The content of the synthesized α-linolenic acid (18:3) is very high, which is 3 to 4 times that of soybean oil and rapeseed oil. After the human body ingests it, it can be converted into EPA and DHA to play a role; it l...
