Embodiment 1

[0034] 1) Weigh 0.60g of chitosan in 60mL of 1% acetic acid solution by volume fraction, and ultrasonically disperse at room temperature for 30min to obtain a clear solution of chitosan-acetic acid, which is designated as solution A.

[0035] 2) Adjust the pH value of solution A obtained in step 1) to 2, add 20ml of tea polyphenol solution with a mass fraction of 10%, and obtain chitosan-tea polyphenol mixed colloid, which is denoted as colloid B. Chitosan forms a gel state after being dissolved in water, and has strong adsorption properties. Using this property, it can effectively absorb a large number of tea polyphenol molecules, forming an antibacterial and moisture-absorbing fresh-keeping structure.

[0036] 3) Weigh 2.00g of sodium carboxymethyl cellulose in 100mL of deionized water, ultrasonically disperse at room temperature for 30 minutes, add dropwise to the colloid B obtained in step 2) while stirring, and mix well to obtain mixed colloid C. Sodium cellulose has good...

Embodiment 2

[0043] 1) Weigh 0.80g of chitosan in 60mL of acetic acid solution with a volume fraction of 1.5%, and ultrasonically disperse at room temperature for 30min to obtain a clear solution of chitosan-acetic acid, which is designated as solution A.

[0044] 2) Adjust the pH value of solution A obtained in step 1) to 4, add 25ml of tea polyphenol solution with a mass fraction of 15%, and obtain a chitosan-tea polyphenol mixed colloid, which is denoted as colloid B. Chitosan forms a gel state after being dissolved in water, and has strong adsorption properties. Using this property, it can effectively absorb a large number of tea polyphenol molecules, forming an antibacterial and moisture-absorbing fresh-keeping structure.

[0045] 3) Weigh 2.50g sodium carboxymethyl cellulose into 100mL deionized water, ultrasonically disperse at room temperature for 30min, add dropwise to colloid B obtained in step 2) while stirring, and mix well to obtain mixed colloid C, due to carboxymethyl Sodium...

Embodiment 3

[0052] 1) Weigh 1.00 g of chitosan in 60 mL of acetic acid solution with a volume fraction of 2%, and ultrasonically disperse at room temperature for 30 min to obtain a clear solution of chitosan-acetic acid, which is designated as solution A.

[0053] 2) Adjust the pH value of solution A obtained in step 1) to 7, add 30ml of tea polyphenol solution with a mass fraction of 20%, and obtain chitosan-tea polyphenol mixed colloid, which is denoted as colloid B. Chitosan forms a gel state after being dissolved in water, and has strong adsorption properties. Using this property, it can effectively absorb a large number of tea polyphenol molecules, forming an antibacterial and moisture-absorbing fresh-keeping structure.

[0054] 3) Weigh 3.00g sodium carboxymethyl cellulose into 100mL deionized water, ultrasonically disperse at room temperature for 30min, add dropwise to colloid B obtained in step 2) while stirring, and mix well to obtain mixed colloid C, due to carboxymethyl Sodium ...

Abstract

The invention relates to the technical field of specimens, and discloses a storage method of insect specimens, which comprises the following steps: adding an antibacterial composite pad with bacteriostatic action and drying and moisture-absorbing action into an insect specimen box, boxing the insect specimens according to normal steps, and then packaging the box in vacuum by using a transparent sealing bag. And insect specimens are protected as much as possible. According to the method, the food preservation technology is creatively applied to preservation of the insect specimens, the method has extremely high application value in storage and transportation of the insect specimens, and the preservation performance of the method is also very excellent through vacuum sealing preservation.

Description

technical field [0001] The invention relates to the technical field of specimens, in particular to a method for storing insect specimens. Background technique [0002] There are about 1 million species of insects known in the world, accounting for more than 70% of the species in the entire animal kingdom. Hundreds of millions of years ago, countless insects were preserved and continued to this day in the form of fossils. Insect fossils can not only preserve the original morphological characteristics of insects, but also record the internal genes of insects. In recent years, the rapid development of entomology, ecology, biochemistry, pharmacology and other disciplines has further promoted the development and utilization of insect resources. As an important part of biological resources, insect specimens are the basic materials for animal and plant quarantine, pest control and other research and course teaching. [0003] However, after the insect specimens are prepared, alth...
