Embodiment 1

[0017] First, crush 500 kg of soybean meal as a raw material and soak it in 400 kg of water. The weight ratio of the amount of water added to the soybean meal is 0.8:1, and the soaking time is 5 hours before use.

[0018] Add 98% sulfuric acid to the soaked soybean meal mixed liquid, wherein the weight ratio of sulfuric acid to liquid is 1:2, raise the temperature to a constant temperature of 100°C, under normal pressure, hydrolyze for 6 hours, the hydrolysis temperature is 100°C, and stir at the same time, the stirring speed is 80°C RPM, cooled to normal temperature, after hydrolysis, use 115 kg of calcium hydrogen carbonate to neutralize to reach a pH value of 4-6, then place the neutralized solution for precipitation and filter, and the obtained filtrate is the tan compound amino acid stock solution.

[0019] 500 kg of compound amino acid stock solution is adsorbed and decolorized with 50 kg of activated carbon, the amount of activated carbon accounts for 10% of the weight, ...

Embodiment 2

[0021] First, crush 500 kg of safflower meal as a raw material and soak it in 900 kg of water. The weight ratio of the amount of water added to the sunflower meal is 1.8:1, and the soaking time is 13 hours before use.

[0022] Add 95% hydrochloric acid to the soaked safflower meal mixed liquid, wherein the weight ratio of hydrochloric acid to liquid is 1:1, heat up to a constant temperature of 130°C, under normal pressure, hydrolyze for 13 hours, and the hydrolysis temperature is 110°C, while stirring, the stirring speed 50 rpm, cooled to normal temperature, after hydrolysis, use 500 kg of calcium hydroxide to neutralize to reach a pH value of 6, then place the neutralized solution for precipitation and filter, and the obtained filtrate is the tan compound amino acid stock solution.

[0023] The compound amino acid stock solution is decolorized, deodorized, concentrated, and sterilized by conventional membrane separation technology to obtain a refined compound amino acid liquid...

Embodiment 3

[0025] First, crush 500 kg of peanut meal as raw material and soak it in 500 kg of water. The weight ratio of the amount of water added to the peanut meal is 1:1, and the soaking time is 20 hours before use.

[0026] Add 93% sulfuric acid to the soaked peanut meal mixed liquid, wherein the weight ratio of sulfuric acid to liquid is 1:1.5, raise the temperature to a constant temperature of 90°C, and keep the pressure at 2.5kg / cm 2 , hydrolyzed for 12 hours, stirring at the same time, the stirring speed was 60 rpm, the hydrolysis temperature was 115°C, cooled to room temperature, after hydrolysis, use 500 kg of calcium carbonate to neutralize the pH value to 5, then place the neutralization solution to precipitate and filter , the resulting filtrate is the brown complex amino acid stock solution.

[0027] The compound amino acid stock solution is added with a total amount of 20% of a large amount of nitrogen, phosphorus, and potassium, 10% of a total amount of calcium, magnesium...

Abstract

A vegetative compound amino acid is prepared through preparing its primary liquid from vegetative protein (bean dregs, peanut dregs, etc.) as raw material by hydrolysis of sulfuric acid or hydrochloric acid, decolouring and deodouring by activated carbon adsorption or membrane separation technique, and concentrating. The product can be used to prepare liquid fertilizer or compound amino acid powder used as additive for food, feed, medicine, etc.

Description

technical field [0001] The invention relates to a refined plant compound amino acid used in medicine, food, health care, feed, daily cosmetics and compound fertilizer additives and its production method Background technique [0002] Amino acid is the basic unit of protein and has extremely important physiological functions. It is widely used in food, medicine, feed, cosmetics and other industries closely related to human life and health. At present, the annual output of amino acids in the world is about 2 million tons. The production methods of amino acids include direct fermentation, precursor addition fermentation, enzymatic method, hydrolysis method and chemical synthesis method and other traditional classic methods. Due to the rapid development of fermentation and enzyme engineering, the production cost has been greatly reduced, so it has replaced the hydrolysis method to produce amino acids. However, some amino acids still need to be produced by ac...
