Abstract

The invention discloses an extraction method and application of firefly chitosan, and further provides a fodder. The extraction process of the firefly chitosan comprises the steps of cleaning and drying fresh fireflies, then decalcifying, removing protein and decoloring, and finally, extracting through an ultrasonic technology matched with the solvent under the aid of alkali, so as to obtain the chitosan. In the extraction process of the firefly chitosan, decalcification and deacetylation help reduce product impurities effectively, the ultrasonic technology cooperates with the solvent so as tofurther promote deacetylation, so that the product quality is higher, and the product can improve the immunity when being used in the fodder and can prohibit bacteria activity,.

Description

technical field

[0001] The invention relates to a method for extracting chitosan, in particular to a method for extracting chitosan from fireflies. Background technique:

[0002] Fireflies are insects of the Fluoridae family of Coleoptera. They are called fireflies because their tails can emit fluorescence. In order to protect itself, its body is flat and slender, its head is small, its body wall and elytra are soft, and its head is covered by a large pronotum cover, which is rich in chitosan.

[0003] Chitosan, also known as deacetylated chitin, is obtained through deacetylation of chitin, which exists widely in nature, and has a wide range of uses.

[0004] There are few related reports on the extraction and utilization of firefly chitosan, and there is no information on the extraction and utilization of firefly chitosan. Invention content:

[0005] The object of the present invention is to provide a kind of method that extracts chitosan from firefly, to solve above-me...
