Abstract

The invention discloses a preparation method for starch adhesive used for sea eel feedstuff and belongs to the technical field of feedstuff additive preparation.With cassava starch being a raw material, the cassava starch is pretreated through grafting and cross-linking denaturation methods and then dried to prepare the starch adhesive.The graft and cross-linking denaturation methods are combined with the pregelatinization method, so that the starch adhesive used for the sea eel feedstuff is of a multi-dimensional net-shaped structure and is endowed with a better film-forming property, better adhesion and better anti-aging performance; the starch adhesive used for sea eel feedstuff can improve the stability of the feedstuff in water and increase the utilization rate of the feedstuff, reduce the loss of feedstuff nutrients and reduce pollution to a breeding environment.

Description

【Technical field】 [0001] The invention belongs to the technical field of feed additive preparation, and in particular relates to a preparation method of a starch binder for eel feed. 【Background technique】 [0002] In recent years, with my country's emphasis on the aquaculture industry, artificial eel breeding has developed rapidly, and the breeding area has expanded and the output has increased rapidly. With the popularization and improvement of eel breeding technology, the requirements for feed quality are getting higher and higher, and the quality of eel feed mainly depends on the quality of raw materials used. The raw materials of eel feed mainly include fish meal, pregelatinized starch, gluten powder, yeast and compound additives, among which the proportion of fish meal and pregelatinized starch is very large, and the sum of the two often accounts for 80%-90% of all raw materials , wherein the amount of pregelatinized starch is as high as 20%-25%. [0003] Pregelatini...
