Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chitin content analysis in yellow mealworm powder, and particularly relates to a pretreatment device for chitin content analysis in yellow mealworm powder. Background Technique
[0002] Chitin and chitosan are natural biopolymers existing in lower animals, especially in the outer shells of arthropods and in the cell walls of lower fungi and yeasts, belonging to linear polysaccharides.
[0003] The yellow mealworm is an important stored grain pest distributed all over the world, commonly known as the bread worm. The chitin content in the yellow mealworm is relatively high, about 12.55%. Compared with the chitin prepared from shrimp shells, the chitin extracted from the yellow mealworm has a lower ash content and a lower molecular weight, and can be further used to prepare chitosan with a low molecular weight and a high degree of deacetylation. The effects of residual protein and ash content under different extraction process conditions on chitin in yellow mealworms are different. Therefore, it is necessary to detect and analyze the chitin extracted from yellow mealworms.
[0004] When detecting and analyzing chitin samples, pretreatment is required. Among them, suction filtration is one of the important steps in pretreatment. Most of the existing suction filtration methods are carried out through a Buchner funnel. However, this method cannot perform suction filtration treatment on chitins extracted by multiple different processes at the same time, and only provides single Buchner funnel suction filtration, resulting in poor separation effect.
