Abstract

The invention relates to a preparing method of a lotus seed amylase-aliphatic acid composite having a high composite index number, and belongs to the technical field of modified starch processing. The method includes preparing lotus seed amylase into submicron order particles through superfine grinding, and forming the single-screw V-type amylase-aliphatic acid composite through microwave pretreatment and ultrahigh pressure treatment in assistant. The composite has the ultra-high composite index number and an embedding rate. The method includes steps of preparing the amylase, performing superfine grinding, pretreating aliphatic acids, performing microwave pretreatment, performing ultrahigh pressure compositing, cooling and crystallizing at a low temperature, washing with an alcohol, centrifuging, freeze-drying, smashing and packaging. A product of the method is high in composite index number, good in digestion resistibility and high in embedding rate. Compared with traditional preparing methods, a process of preparing the composite is free of chemical agent addition and high in safety, the composite can provide a sense of satiety and reduce blood glucose when the composite is added into foods, and the composite has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of modified starch processing, and in particular relates to a preparation method of lotus seed amylose-fatty acid compound with high composite index. Background technique [0002] Starch is a high-molecular carbohydrate that exists widely in nature. Its content is second only to cellulose. It is considered to be the main source of energy in human nutrition and an important raw material in food processing. Starch is divided into amylose and amylopectin. When there are small molecular guest substances such as fatty acids in the starch solution, the hydrogen bonds in the amylose molecule will cause the starch chain to curl, resulting in an internal hydrophobic structure, and internal complexation with some organic or inorganic hydrophobic groups. The fatty acids act as molecular entrapments, thereby forming complexes. Studies have shown that amylose-fatty acid complexes can reduce the digestibility of starch,...
