Problems solved by technology

However, in the spray drying technology itself, the atomized material is dried by hot air flow at high temperature. During this process, unsaturated fatty acids still have the risk of being oxidized by high temperature and losing their activity.

Abstract

The invention relates to the technical field of embedding and discloses a polymer-embedded unsaturated fatty acid composition and a spray drying preparation method thereof. The unsaturated fatty acidcomposition uses at least one of beta-cyclodextrin, a glue wall material and a protein wall material together with a polymer as a wall material, and uses an unsaturated fatty acid as a core-shell structure of a core material. The polymer is a propyl-N-isopropylacrylamide-acrylic acrylamide copolymer. The unsaturated fatty acid composition can avoid the oxidation of unsaturated fatty acids during the preparation process as well as during the storage process.

Description

technical field [0001] The invention relates to the field of embedding technology, in particular to a polymer-embedded unsaturated fatty acid composition and a spray-drying preparation method thereof. Background technique [0002] Unsaturated fatty acid is a kind of fatty acid that constitutes body fat and is an indispensable fatty acid for the human body. Unsaturated fatty acids are divided into monounsaturated fatty acids and polyunsaturated fatty acids according to the number of double bonds. Among food fats, monounsaturated fatty acids include oleic acid, etc., and polyunsaturated fatty acids include linoleic acid, linolenic acid, and arachidonic acid. [0003] In the prior art, there are various forms of unsaturated fatty acid products, among which powder form is the main product. When it is prepared in powder form, since unsaturated fatty acid is easily oxidized by high temperature, it is usually spray-dried, and protein, sugar Or glue and other substances are used a...
