Problems solved by technology

[0006] Chinese patent CN1386497 discloses "α-linolenic acid microcapsules and its manufacturing method". The purity of the raw material α-linolenic acid used in this patent is relatively low (60%-90%); in addition, gum arabic is used as an emulsifier in the formula , due to the low viscosity of gum arabic, it is easy to cause emulsification and stratification when used alone as an emulsifier, so the embedding rate is low and the surface oil content is high
[0008] Chinese patent CN101336905 discloses "a production method of α-linolenic acid microcapsules", using corn protein porous starch granules as a carrier, and preparing corn protein starch into 5-10% alcohol-soluble corn with 80-90% ethanol The protein solution is used as an embedding agent (wall material) to coat the carrier, and oleic acid is used as a plasticizer. The raw material used in this patent is cold-pressed linseed oil, and the content of each component of the linseed oil is not further explained; the carrier zein Some physical properties of porous starch granules, such as shear resistance, viscosity stability, and granule firmness, are lower than those of native starch granules, and the embedding effect is not ideal
The wall materials used are modified starch, gum arabic, and maltodextrin, and the mass concentration of the wall material solution is too low (5%-10%), which will easily lead to a low embedding rate
[0011] Chinese patent CN105029409 discloses "a linseed oil microcapsule and its preparation method". The raw material in this patent is refined linseed oil, and the content of α-linolenic acid in linseed oil is not further explained, and the wall material The dosage (mass percentage) is low (1%-10%), resulting in low embedding rate and high surface oil content
Oxygen in the air easily enters the solution, and the heat generated by high-speed stirring will oxidize and deteriorate α-linolenic acid, thereby affecting the yield of the reaction.

Abstract

The invention relates to an alpha-linolenic acid microcapsule capable of being directly used for cooking and a preparation method of the alpha-linolenic acid microcapsule. The alpha-linolenic acid microcapsule is prepared from alpha-linolenic acid, alpha-linolenic acid ethyl ester or alpha-linolenic acid glyceride as well as an antioxidant, an emulsifier, a wall material and water, wherein the purity of alpha-linolenic acid, alpha-linolenic acid ethyl ester or alpha-linolenic acid glyceride is larger than or equal to 85wt%; the alpha-linolenic acid, alpha-linolenic acid ethyl ester or alpha-linolenic acid glyceride accounts for 5%-40% of the microcapsule in percentage by mass, the wall material accounts for 20%-80% of the microcapsule in percentage by mass, the emulsifier accounts for 0.01%-8% of the microcapsule in percentage by mass, and the antioxidant accounts for 0.001%-3% of the microcapsule in percentage by mass; the antioxidant is a combination of a water-based antioxidant and an oily antioxidant. The high-content alpha-linolenic acid microcapsule has high grease embedding rate and good embedding performance, and oxidative deterioration of alpha-linolenic acid is effectively slowed down.

Description

technical field [0001] The invention belongs to the technical field of oil production, and in particular relates to an alpha-linolenic acid microcapsule which can be directly used for cooking and a preparation method thereof. Background technique [0002] α-Linolenic acid (ALA) is an omega-3 unsaturated fatty acid and cannot be synthesized in the human body. It is recognized worldwide as an essential fatty acid that can only be supplemented by eating. In nature, α-linolenic acid is mainly derived from linseed oil, and the mass percentage of α-linolenic acid is generally 50%-60%. Studies have shown that α-linolenic acid can regulate the immune system, has the function of lowering blood fat and blood viscosity, and has certain effects on human early nutrition, infant brain development, cardiovascular and cerebrovascular diseases, malignant tumor suppression, hyperlipidemia, etc. effect. [0003] Edible oil is the main way for the human body to absorb fatty acids. It has been...
