Embodiment 1

[0019] see figure 1 Electric heating cycle diagram of heat transfer oil using jacketed reactor.

[0020] Extract a ton of MSG production waste - glutamic acid-producing bacteria cells, using protease hydrolysis process: the first step is to pre-treat the cell protein, the purpose of pre-treatment is to fully denature the protein, molecular The structure is loose, so that the protein is easy to decompose under the catalysis of protease;

[0021] The pretreatment process conditions are as follows: dilute hydrochloric acid to 2%, add bacterial protein, the liquid-solid ratio is 3.5:1, then keep the heating temperature at 95±1°C, and the heating time is 1.5 hours, and the pretreatment is completed;

[0022] The second step is to move the pretreated bacterial protein to the enzyme kettle, adjust the pH=7.5, the concentration is 1:30, and the enzyme addition is 14%, and heat it. The heating temperature is 40°C and the time is 12 hours. be hydrolyzed into amino acids.

Embodiment 2

[0024] see figure 1 Electric heating cycle diagram of heat transfer oil using jacketed reactor.

[0025] Extract one ton of MSG production waste - glutamic acid-producing bacteria cells, and use the acid hydrolysis process: use sulfuric acid as a catalyst to hydrolyze the cells' protein at a certain temperature.

[0026] The process is to put the bacterial protein and dilute sulfuric acid (hydrochloric acid can also be used) adjusted to a concentration of 6N into the reactor, and the solid-to-liquid ratio is 2:3 (by weight), and heat it after sealing the kettle. The temperature is maintained at 110°C for 24 hours, the bacterial protein is hydrolyzed into amino acids, and then the lid is opened to take out the liquid for filtration and neutralization.

Abstract

The present invention relates to a method for preparing amino acid foliage fertilizer by utilizing polypeptide, amino acids and its intermediate product mixed solution obtained by hydrolyzing cheap protein resource-discarded material resulted from production of monosodium glutamate as raw material. Said invention adopts two production processes; first is enzymolysis, i.e. adopts proteinase hydrolysis and second process is acidolysis; using sulfuric acid or hydrochloric acid as catalyst, under the condition of a certain temp. hydrolyzing somatic protien. Said two processes can obtain the invented amino acid organic fertilizer.

Description

technical field [0001] The invention relates to an organic fertilizer used by plants, in particular to a preparation method of a novel amino acid foliage fertilizer. Background technique [0002] The production of monosodium glutamate is to use grain as raw material to produce products. However, during the production process, a large amount of nutrient-rich organic matter will be discharged into the sewer and into the river. Due to the large amount of organic matter, it promotes the proliferation of microorganisms, making it Rapid hypoxia causes aquatic organisms to suffocate and die, and causes environmental pollution and other problems. And bacterial protein is discharged along with waste, causes waste again. Therefore, it is an urgent problem to be solved in today's monosodium glutamate production to separate the bacterium protein in the waste and make use of it to reduce environmental pollution and turn waste into treasure. [0003] Hydrolyzed vegetable protein is wide...
