Description

Natural plant compound microcapsule for aquatic product transportation and keep-alive and application thereof Technical Field The invention belongs to the technical field of aquaculture, and particularly relates to a natural plant compound microcapsule for aquatic product transportation and survival and application thereof. Background Along with the improvement of the living standard of people, the demand for fresh aquatic products is growing increasingly, and the fresh transportation of the aquatic products becomes a key ring for improving the aquaculture benefits. The traditional aquatic product transportation mode often causes water quality deterioration because of long-time transportation, and the aquatic product is damaged or dead due to hypoxia, stress reaction and other reasons, so that the transportation efficiency is reduced, and the production and operation cost is increased. Therefore, how to keep the water quality stable and reduce the stress reaction of the aquatic products becomes a problem to be solved urgently in the transportation process of the aquatic products. At present, chemical reagents are mostly adopted in the market to carry out transportation and keep-alive of aquatic products, such as the common fish transportation and keep-alive reagent, namely, tricaine mesylate. In addition, the aquatic product keep-alive reagent in the experimental research stage is mainly chemical agents, such as 2-phenoxyethanol, diethyl ether, ethanol and the like. The use of chemical agents presents a residual risk that may affect food safety and pose a potential threat to human health. The development of the aquatic product transportation method capable of effectively improving the survival rate of aquatic products and maintaining the safety of food is an important direction of technical development in the current aquatic product industry.
