Abstract

The invention discloses a method for extracting mylabris chitosan and its application, and also includes a pet health care feed. The preparation process of the mylabris chitosan is roughly as follows: the mylabris chitosan is washed, dried, and pulverized, degreased, extracted with EDTA under the assistance of ultrasound, and finally decolorized and deacetylated to obtain the desired mylabris chitosan. The invention can effectively and rapidly extract the chitosan in the mylabris, has industrialization potential, and the extracted chitosan can effectively improve the efficacy of the pet health care feed when applied to the pet feed.

Description

technical field [0001] The invention relates to a method for extracting chitosan, in particular to a method for extracting chitosan from mylabris. Background technique: [0002] Spotted beetles, aliases are also known as spotted oysters, piebald hairs, tabby cats, coriander greens, flower beetles, Zhangwa, soybean worms, etc., commonly known as Spanish flies. [0003] Chitin is widely found in insect shells, which are further processed to give chitosan. This type of substance has high stability, and the viscosity of the product can be effectively adjusted by adding chitosan, and it has certain biological safety and will not cause other adverse effects. [0004] For the extraction of cantharidin components, most of the current research focuses on the extraction of cantharidin, while there are few reports on the extraction of other components. Invention content: [0005] The object of the present invention is to provide a method for extracting chitosan from mylabris. The ...
