Problems solved by technology

Adding ethyl conjugated linoleate directly to edible oil can provide a convenient way to supplement conjugated linoleic acid, but this kind of oil has a low smoke point and poor flavor, and it is difficult to achieve the versatility of ordinary edible oil. Purpose
At present, conjugated linoleic acid products that can be used as general-purpose edible oils have not yet appeared, and there are no related research reports

Embodiment 1

[0026] Get the fatty acid ethyl ester that comprises 70% conjugated linoleic acid and soybean oil mixture 10kg and place in the reactor, control the weight ratio of conjugated linoleic acid ethyl ester (in pure matter) and soybean oil to be 1: 60, in two 5% immobilized lipase LipozymeTLIM (product of Novozymes Company) was added to the mixture, and stirred at 200 rpm and reacted at 35° C. for 3 hours. The reactant was molecularly distilled at 150°C to remove fatty acid ethyl ester and free fatty acid to obtain oil 1.

Embodiment 2

[0028] Get the fatty acid ethyl ester that comprises 70% conjugated linoleic acid and soybean oil mixture 10kg and place in the reactor, control the weight ratio of conjugated linoleic acid ethyl ester (in pure matter) and soybean oil to be 20: 60, combine two The mixture of the former passed through a packed bed reactor equipped with immobilized lipase Lipozyme TLIM, the reaction temperature was 70°C, and the residence time of the oil in the reactor was 0.5 hours. The reactant was molecularly distilled at 150°C to remove fatty acid ethyl ester and free fatty acid etc. to obtain oil 2.

Embodiment 3

[0030] Get the fatty acid ethyl ester that comprises 70% conjugated linoleic acid and rapeseed oil mixture 10kg and place in the reactor, control the weight ratio of conjugated linoleic acid ethyl ester (in pure matter) and soybean oil to be 6: 60, will The mixture of the two passed through a packed bed reactor equipped with immobilized lipase Lipozyme TLIM, the reaction temperature was 70°C, and the residence time of the oil in the reactor was 1 hour. The reactant is distilled under reduced pressure at 230°C, and high-purity nitrogen is constantly blown in during the distillation process to remove fatty acid ethyl ester and free fatty acid to obtain oil 3.

Abstract

The present invention relates to one kind of grease containing glyceride type conjugated linoleic acid and its production process. The grease includes glyceride type conjugated linoleic acid in 1-15 wt%, and over 88 % of the conjugated linoleic acid is located in the 1st and 3rd position. The production process includes the following steps: 1. mixing conjugated linoleic acid donor and triglyceride type grease in the weight ratio of 1-20 to 60; 2. lipase catalyzed reaction of the mixture at 35-90 deg.c; and 3. distilling the reaction product for separating and collecting the glyceride product with combined conjugated linoleic acid. The obtained product may be used to replace common edible oil for replenishing conjugated linoleic acid possessing the health functions of antagonizing atherosclerosiss, resisting cancer, slimming, etc.

Description

technical field [0001] The invention relates to a kind of oil and its production method, in particular to a kind of oil containing glyceride type conjugated linoleic acid and its production method. Background technique [0002] Conjugated linoleic acid (abbreviated as CLA) is a general term for a mixture of stereo and positional isomers of linoleic acid. Its conjugated double bonds are usually located at C9 and C11 or C10 and C12, and each double bond can exist in cis or trans configuration, among which 9c, 11t and 10t, 12c are the most important forms of CLA. Studies have shown that conjugated linoleic acid is a strong anti-cancer substance, has anti-atherogenic properties, anti-diabetes, anti-allergic, immune regulation, growth promotion, reducing body fat and increasing lean mass and affecting bone formation and other physiological functions. [0003] Natural sources of CLA mainly exist in milk fat and meat products of ruminants. CLA in meat and milk fat of ruminants is...
