Abstract

The invention discloses a preparation method of a starch-C18 fatty acid compound.The method includes the steps that high amylase corn starch and C18 fatty acid, namely, stearic acid or oleic acid or soya oil acid or alpha-linolenic acid, serve as the raw materials, and through the purification of starch, the starch-C18 fatty acid compound is formed, purified and prepared.The method has the advantages that the defect that fatty acid is prone to oxidation is overcome, the enzyme resistance of starch is improved, and the compound yield can reach about 70% at most, and high application prospects are achieved on the aspects of food production and processing.

Description

field of invention [0001] The invention belongs to the technical field of agricultural product processing, in particular to a preparation method of starch-C18 fatty acid complex. Background technique [0002] Long-chain fatty acids are often used as the main source of nutritional energy. In particular, some fatty acids (fatty acid salts) have healthy functional properties but are poorly synthesized from their precursor cells and must therefore be obtained from the diet. However, these important fatty acids are easily oxidized and lose some of their functions during food processing, storage, and / or consumption. In order to overcome these defects, various packaging technologies have been widely researched and applied. These techniques, such as those involving complex formation of liposomes and cyclodextrins, offer possible solutions for improving storage stability and water dispersibility. [0003] As the main ingredient of staple food, starch is the main carbohydrate in th...
