Problems solved by technology

[0005] The technical problem solved by the present invention is that in the prior art, although linseed oil is rich in α-linolenic acid, which is beneficial to the human body, since α-linolenic acid is octadecatrienoic acid, its structure contains Three double bonds are easy to oxidize and become rancid, and the taste of α-linolenic acid is greatly affected after oxidation and rancidity, the quality of oil changes, the shelf life is short, and as a fat-soluble acid, it is not easily absorbed by the human body. Absorption, thereby affecting its conversion rate into EPA and DHA in the human body, reducing the actual edible value of linseed oil, and then providing an optimized linseed oil microcapsule powder and its preparation process

Abstract

The invention relates to linseed oil microcapsule powder and a preparation process thereof. The microcapsule powder is prepared from the following components in parts by weight: 38-45 parts of linseed oil, 0.002-0.02 part of an antioxidant, 48-54 parts of a filling agent, 6-8 parts of an emulsifier, 0-0.1 part of a stabilizer and 65-80 parts of water. The preparation process comprises the following steps: preparing an aqueous phase, preparing an oil phase, performing pre-emulsification, homogenizing and granulating. According to the final product obtained in the technical scheme of the invention, the surface is spherical under an environment scanning electron microscope, the particle size ranges from 35 microns to 100 microns, and the obtained product is a quick-dissolving product and is high in liquidity, high in re-watering stability, high in microcapsule oil embedding rate, good in embedding performance, good in taste and high in absorption rate; and moreover, the preparation process is simple, large-scale production is conveniently realized, contact between the linseed oil and air is effectively isolated by virtue of the microcapsule embedding technology, the biological activity of alpha-linolenic acid in the linseed oil is protected, waste residues and wastewater are not produced in the production process, and the product is green and environment-friendly.

Description

Technical field [0001] The invention belongs to the technical field of food, foodstuffs or non-alcoholic beverages; their preparation or treatment, such as cooking, nutritional quality improvement, physical treatment; general preservation of foods or foodstuffs, and particularly relates to a flaxseed oil microcapsule powder and the same Preparation Process. Background technique [0002] Omega-3 polyunsaturated fatty acids are the core substance of life. They are essential fatty acids that maintain the evolution of the human body and keep the body healthy. The human body cannot synthesize by itself and can only be ingested from food to meet the body's needs. Alpha-linolenic acid is the "parent" of the omega-3 unsaturated fatty acid family. It can be transformed into the human body's essential life active factor-EPA (twenty-two) in the human liver under the action of desaturase and elongase. Carbopentaenoic acid, commonly known as vascular scavenger) and DHA (docosahexaenoic acid,...
