Embodiment 1

[0014] A linseed oil rich in conjugated linoleic acid, which is composed of conjugated linoleic acid and compound antioxidants added to linseed oil, wherein the conjugated linoleic acid is a natural extract, and the added amount is 1% of the total linseed oil mass 1%; the composite antioxidant is made of tea polyphenols in an amount of 0.01% of the total linseed oil quality, L-ascorbyl palmitate in an amount of 0.1% of the total linseed oil quality and an amount of 0.1% of the total linseed oil quality Composition of 0.005% Vitamin E. The tea polyphenols are fat-soluble tea polyphenols.

[0015] The unroasted flax seeds are used as raw materials to produce linseed oil by screw pressing, and after filtration and cooling and refining, some impurities are removed to obtain refined linseed oil. This kind of linseed oil produced by physical pressing and physical refining retains more nutrients such as linseed lignans, phospholipids, vitamins, etc., but this linseed oil has a high ...

Embodiment 2

Abstract

The invention belongs to the technical field of linseed oil production, and provides linseed oil rich in conjugated linoleic acid (CLA) so as to solve the problems that the shelf life of the linseed oil is shortened due to proneness to rancidity and the quality of the linseed oil is unstable caused by the fact that nutritional ingredients are damaged. The CLA and a composite antioxidant are added into the linseed oil, the adding quantity of the CLA accounts for 1%-4% of the total mass of the linseed oil; and the composite antioxidant comprises tea polyphenol, L-ascorbyl palmitate and vitamin E, the adding quantity of the tea polyphenol accounts for 0.01%-0.1% of the total mass of the linseed oil, the adding quantity of the L-ascorbyl palmitate accounts for 0.01%-0.1% of the total mass of the linseed oil, and the adding quantity of the vitamin E accounts for 0.005%-0.08% of the total mass of the linseed oil. According to the linseed oil rich in CLA, nutrient substances such as secoisolariciresinol diglucoside, phospholipid, vitamin and the like are more reserved, a packed product of the produced linseed oil is suitable for cold storage, the guarantee period under cold storage reaches 24 months, and the guarantee period at the ordinary temperature reaches 18 months. With addition of the CLA, the linseed oil is rich in both alpha-linolenic acid and the CLA, so that a functional unsaturated fatty acid is balanced and comprehensive.

Description

technical field [0001] The invention belongs to the technical field of linseed oil production, in particular to linseed oil rich in conjugated linoleic acid. Background technique [0002] Conjugated linoleic acid (CLA) can improve human immunity, regulate blood pressure, reduce body fat mass, and also have anti-cancer, anti-arteriosclerosis, prevent diabetes, etc., and have antioxidant effects. Conjugated linoleic acid mainly exists in ruminal animals, such as milk fat and meat products of cattle and sheep, and the content of conjugated linoleic acid in plant and marine foods is very small. As a functional food additive, conjugated linoleic acid can be added to milk, bread, ham sausage, candy, dairy products, meat products and other foods, and can also be added to vegetable oil. [0003] The active ingredient in linseed oil that plays a health function is α-linolenic acid, which accounts for more than 45% of the fatty acid composition of flaxseed, so linseed oil is an impor...
