Problems solved by technology

However, AA oil cannot withstand high temperature when exposed to the air, and is also easily oxidized, so it is difficult to directly add it to infant formula under the condition of effectively maintaining its activity
[0004] Hubei Fuxing Biotechnology Co., Ltd. discloses a micron-sized arachidonic acid emulsion and its preparation method in its patent CN101258929A. It is added to liquid substances, so its application range is not very wide, which limits the application of AA as a nutritional enhancer to a certain extent.

Abstract

The invention discloses an arachidonic acid nutrition microcapsule with high temperature resistance. Arachidonic acid is taken as a core material and is wrapped in the microcapsule. The wall of the microcapsule is two-layered, wherein, the inner layer is a mixture of a capsule wall material I and an antioxidant, the outer layer is a capsule wall material II. The weight percentages of the ingredients are as follows: the arachidonic acid: 10-30%, the capsule wall material I: 40-60%, the antioxidant: 1-2% and the capsule wall material II: 10-30%. The capsule wall material I is a mixture of any one or two of maltodextrin, cyclodextrine and hydroxyl propyl cellulose in arbitrary proportion, while the capsule wall material II is a mixture of any one or two of starch anhydride of octenyl succinic, alginate, corn dextrin, gelatin and acacia in arbitrary proportion. The invention also discloses a preparation method of the arachidonic acid nutrition microcapsule with high temperature resistance. The invention greatly improves heat resistance and oxidation stability of the arachidonic acid nutrition microcapsule, thus extending the shelf life of products.

Description

technical field [0001] The invention relates to a preparation and a preparation method thereof, in particular to a heat-resistant arachidonic acid nutritional microcapsule and a preparation method thereof. Background technique [0002] Arachidonic Acid (AA for short, namely 5,8,11,14-eicosatetraenoic acid) belongs to the omega-6 series of long-chain polyunsaturated fatty acids. AA is an important essential fatty acid for human body, and it is the derivative of many carbon atoms such as prostaglandin E 2 (PGE 2 ), prostacyclin (PGI 2 ), Thromboxane A 2 (TXA 2 ), Leukotirene B 4 (LTB 4 ) and C4 (LT C 4 ), these biologically active substances have an important regulatory effect on lipoprotein metabolism, hemorheology, vascular elasticity, leukocyte function and platelet activation. However, AA cannot be synthesized de novo in the human body, but must be synthesized by elongation and desaturation of the essential fatty acid linoleic acid. Most of the AA must be provided...
