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 hig

Example Embodiment

[0024] Example 1

[0025] A method for improving the hydrolysis and synthesis rate of hair to prepare aquatic ecological protection agent includes the following steps:

[0026] 1) Wash the hair clean, put it in an oven and dry it until the moisture content of the hair is 10%, crush the hair to a length of 10μm, add keratinase and deionized water at a pressure of 20Mpa and normal temperature, and keep stirring for 10 minutes. A mixed solution A is obtained; wherein the weight ratio of the hair, keratinase and deionized water is 100:5:100, and the hair used for hydrolysis is first crushed into small sections to increase the reaction contact area, which is beneficial to accelerate the rate of the hair hydrolysis reaction. The added keratinase can decompose the keratin in the hair into peptides first. Under high pressure, it can accelerate the speed of keratinase decomposing keratin. It does not need to be carried out at high temperature. The hair or the peptides decomposed into are no...

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...
