Abstract

The invention discloses an extraction method and application of Coridius chinensis chitosan, and further comprises a formula for applying the Coridius chinensis chitosan to feed of Uvarovites inflatus. The extraction method of Coridius chinensis chitosan comprises the following general steps of: performing soaking in dilute hydrochloric acid, adopting acetic acid as a solvent, extracting components by using an ultrasonic-vacuum technology, filtering supernatant, performing decolorization, and finally performing deacetylation treatment by using an alkaline liquid so as to obtain the Coridius chinensis chitosan. Through extraction the chitosan from Coridius chinensis, natural resources can be utilized effectively, the resource consumption rate can be reduced, and meanwhile an effect of improvement of a body immunity function can be achieved after the Coridius chinensis chitosan is made into the feed of Uvarovites inflatus.

Description

technical field [0001] The invention relates to a method for extracting chitosan, in particular to a method for extracting chitosan from wormwood. Background technique: [0002] Nine-scented insects, commonly known as spanking insects, fart insects, etc., belong to the family Pentatomidae of Hemiptera and are important medicinal insects. Its shell is rich in chitosan. [0003] Chitosan is known as "the sixth element of human life" by scientists. It can laxative the intestines, promote digestion, eliminate waste and toxic substances in the digestive tract, and clean up heavy metal ions to prevent and reduce the harm of heavy metal toxins to human organs. Because chitosan is also rich in a large number of biologically active "enzymes", it has significant effects on lowering blood sugar, blood lipids, blood pressure, etc., and has been widely recognized by the medical community. [0004] Chitosan can inhibit the activity of fat-related enzymes, prevent lipase from promoting ...
