Embodiment 1

[0021] Put palm oil stearin and camphor tree seed oil in a ratio of 4 to 6:1 in a temperature-controlled reaction kettle and mix evenly at 65°C. 2 Under the condition of maintaining positive pressure, add 5%~15% Lipozyme RM IM lipase, and react for 6 h~12h at 55 ℃~75 ℃, stirring speed of 300~500 rpm. After the reaction, the crude product was left to stand and filtered. The crude product is deacidified and dehydrated to become a base oil product. The product is rich in medium-chain fatty acids, with a total content of 14.32% to 17.93%, and no trans fatty acids are detected.

Abstract

The invention relates to a method for preparing low / zero trans-fatty acid plastic grease from camphor tree seed oil. The method comprises the following steps of: putting refined camphor tree seed oil and palm oil stearin or fully-hydrogenated soybean oil serving as raw materials into a temperature-controlled reaction kettle, and uniformly mixing the palm oil stearin or the fully-hydrogenated soybean oil with the camphor tree seed oil in the mass ratio (3-6):(4-1) for 1-3 hours; after mixing, adding 5-15 percent of preferred Lipozyme RM IM lipase or TL IM lipase, and reacting at the temperature 55-75 DEG C for 6-12 hours, wherein the optimal temperature is 55-75 DEG C; after reacting, standing for 1-5 hours and filtering the lipase; and deacidifying with 0.05-0.5 N of sodium hydroxide solution and drying in vacuum for 12-24 hours to obtain a finished product. According to the method, low / zero trans-fatty acid plastic grease (including base oil such as margarine, shortening and the like) of different melting points and solid fat contents can be prepared.

Description

[0001] technical field [0002] The invention is a kind of process method of using camphor tree seed oil and palm stearin or fully hydrogenated soybean oil as raw materials to prepare low / zero trans fatty acid plastic oils including margarine, shortening and other base oils through enzymatic transesterification. Oil processing field. Background technique [0003] Our country is very rich in camphor tree resources, which are distributed in the Yangtze River Basin and other provinces in the south. Jiangxi is one of the provinces with the largest total amount of camphor tree resources. There are natural camphor tree forests and artificial forests all over the province, especially in Ji'an area. In my country, camphor tree seeds have been used as medicine for treating diseases for a long time, and it is believed that camphor tree seeds have the effects of dispelling wind and cold, promoting qi and relieving pain. Camphor tree seeds contain a large amount of medium-chain fatty a...
