Embodiment 1

[0019] A preparation method of rubber seed oil, comprising the following steps:

[0020] (1) Get the rubber seeds, dry, peel off, pulverize, and perform supercritical extraction, wherein the process steps of supercritical extraction are: at a temperature of 60°C, a pressure of 30 MPa, and a time of 3 hours, and the entrainer is alcohol. Supercritical CO 2 Extraction adopts primary separation, after separating at a separation temperature of 50° C. and a separation pressure of 9 MPa, and then performing secondary separation at a separation temperature of 45° C. and a separation pressure of 6 MPa to obtain crude oil.

[0021] (2) Take the crude oil, filter, degumming, and deacidification to obtain refined oil.

[0022] Wherein, the process steps of degumming are: carrying out molecular distillation at a temperature of 122° C. and a vacuum degree of 25 Pa. The process steps of deacidification are: carrying out molecular distillation at a temperature of 150° C. and a vacuum degre...

Abstract

The invention discloses a preparation method of rubber seed oil. The method comprises the following steps: (1) taking rubber seeds, drying, peeling, pulverizing, and carrying out supercritical extraction to obtain crude oil; (2) taking the crude oil, filtering, degumming, and deacidifying to obtain refined oil. The method has the advantages that the oil yield of the rubber seed oil is enabled to be 38% or above, the acid value (mgKOH / g) of the rubber seed oil is enabled to be within a range of 0.6-0.7, and the unsaponifiable matter content (%) of the rubber seed oil is enabled to be within a range of 0.08-0.09.

Description

technical field [0001] The invention belongs to the field of rubber processing, in particular to a preparation method of rubber seed oil. Background technique [0002] Rubber seed is a tropical woody vegetable oil plant, the kernel contains 40%-50% oil. Originally produced in Brazil, it is now planted in Yunnan, Guangdong, Hainan and other places in my country. [0003] With the continuous research on rubber seed oil, it is found that rubber seed oil can be used in medicine, food, feed additive and industry. [0004] At present, for the preparation of rubber seed oil, methods such as ultrasonic extraction and solvent extraction can be used, but there are problems such as low oil yield and poor quality of rubber seed oil. Contents of the invention [0005] At the problems referred to above, the purpose of this invention is to provide a kind of good oil quality, the preparation method of the rubber seed oil that oil yield is high. [0006] To achieve the above object, the...
