Abstract

The invention relates to an application of a liquid enzyme preparation in improvement of food texture. The liquid enzyme preparation is glutamine transaminase. The liquid enzyme preparation has the advantages that the food texture can be effectively improved; after proofing by the testing results of protein gel property, compared with the powder enzyme preparation, the water-retaining property and gel property on the protein are better, the dissolving speed is quicker, and the distribution is more uniform; the dust pollution likewise caused by the powder enzyme preparation can be avoided, the storage is convenient, and more safety and health in use are realized; when the liquid enzyme preparation is applied to soybean products, meat products, milk products, aquaculture products and flour products, the product quality is obviously improved, the product texture is improved, the production processing time is effectively shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the application of a liquid enzyme preparation in food texture improvement, in particular to the application of a liquid transglutaminase preparation in soybean products, meat products, dairy products, processed aquatic products and flour products, belonging to food field of processing technology. Background technique [0002] Transglutaminase (EC 2.3.2.13, referred to as TG), also known as transglutaminase, is a commonly used food texture improver in food processing. It can catalyze the formation of ε-(γ -Glutamyl) lysine covalent bond, causing intramolecular and intermolecular cross-linking of proteins, connection between proteins and amino acids, and hydrolysis of glutamine groups in protein molecules, thereby improving the structure and function of proteins. The properties of protein such as: foaming, emulsifying, emulsifying stability, thermal stability, water retention and gelling ability are significantly improved, ther...
