Method for preparing gallic acid aquiculture sanitizer and product thereof

Abstract

The invention provides a method for preparing gallic acid aquiculture sanitizers and products thereof, which comprises the following steps: filtrating gallnut by microwave centrifugation; micro-filtrating; fine-filtrating; ultra-filtrating the fine-filtrated liquid with polysulphone membrane of 50,000 molecular weight, and recycling the trapped fluid by ultra-filtration for extraction; and nano-filtrating the ultra-filtrated dialysate, and recycling the nano-filtrated dialysate for extraction, thus obtaining the products. The products can be made into aqua and powder. The products of the invention have good control effect on various diseases, such as gill-rot disease, white skin disease, red skin disease, scabies disease, fungous saprolegniasis, branchiomycosis and the like, from aquatic animals, such as fish, shrimp, crab, turtle, and frog, etc. Besides, the products do not cause water environmental pollution due to little residue in the aquatic products, so that quality of the products is stable and controllable.

Description

technical field [0001] The invention relates to the preparation of a high-efficiency and low-toxicity disinfectant for aquatic products, in particular to a method for preparing the disinfectant for aquatic products with natural medicine gallic acid and the product thereof. Background technique [0002] my country is a big aquaculture country in the world, and its output accounts for about 80% of the world's aquaculture output. With the continuous expansion of the scale of aquaculture and the continuous improvement of the degree of intensification, coupled with the deterioration of the aquaculture environment, the incidence of aquaculture diseases is increasing, and the pathogens are mainly bacterial diseases. In 2003, 144 species were monitored nationwide. Diseases, including 60 kinds of bacterial diseases, accounting for 41.7%, followed by 39 kinds of parasitic diseases. The direct economic losses caused by breeding diseases in that year amounted to 10.584 billion yuan. I...

Problems solved by technology

These Chinese herbal medicines and aquatic fish medicines are all directly used with raw medicinal materials such as Galla chinensis. The processed dosage form is backward, the drug onset is slow, the bioavailability is low, the drug solubility and product quality are difficult to control, and the control effect is unstable.
