Method for increasing synthetic ratio in hair hydrolyzation for preparing aquatic ecological protecting agent

Abstract

The invention discloses a method for increasing a synthetic ratio in hair hydrolyzation for preparing an aquatic ecological protecting agent. The method comprises the following steps: 1) cleaning, drying and crushing hair, adding keratinase and deionized water and reacting to obtain a solution A under the pressure of 20 to 30 Mpa and normal temperature; 2) selecting one or more of salicylic acid, adipic acid, malonic acid, succinic acid and palmic acid and uniformly mixing with the deionized water to prepare a solution, reacting the obtained solution with the solution A at 10 to 20Mpa and at 30 to 40 DEG C, and filtering to obtain a solution B; 3) selecting one or more of ethylene diamine tetra (methylene phosphonic acid) sodium, diethylenetriaminepenta(methylenephosphonic) acid, amino trimethylene phosphonic acid, tartaric acid, heptonate, sodium gluconate and sodium alginate and uniformly mixing with the deionized water, and then uniformly mixing with the solution B to obtain a finished product. According to the method disclosed by the invention, the time of hair hydrolyzation is shortened, the extraction rate of hair hydrolyzation into amino acids is increased, and therefore the synthetic rate of synthesizing the aquatic ecological protecting agent is increased.

Description

technical field [0001] The invention relates to the technical field of preparation of water ecological protection agents. More specifically, the present invention relates to a method for improving the synthesis rate of hair hydrolysis to prepare water ecological protection agent. Background technique [0002] In the process of aquaculture, the use of chemical drugs to control the disease will not only increase the cost of breeding, but also lead to a decline in product quality and serious environmental pollution. With the progress and development of economy and technology, people's awareness of environmental protection has gradually increased, and the requirements for product quality have also increased, and more and more attention has been paid to environmental pollution. In recent years, hair hydrolyzate has been used as the main component of water ecological protection agents. In industrialized production, it is usually used in the middle and late stages of cultivation a...

Problems solved by technology

At present, the main methods of hydrolyzing hair are high-temperature and high-pressure hydrolysis, acid-base hydrolysis, and enzymatic hydrolysis. However, since high-temperature and high-pressure hydrolysis is generally at 170-370°C, the hydrolyzed amino acids are easily damaged at high temperatures, and even Carbonization; Acid-base hydrolysis generally uses strong acid and strong alkali, which requires high equipment and corrosion resistance. At the same time, the hydrolysis time is generally 8-12 hours; the enzymatic hydrolysis process is slow and takes a long time
