Welcome to inquire! Contact: Mr Tsang. When prepared chemical soy sauce, the cooked meal and other materials soaked in a solution containing a certain amount of hydrochloric acid, keeping a temperature of analytically pure concentrated sulfuric acid, hydrochloric acid having a catalytic protein complex which can promote hydrolysis of concentrated sulfuric acid were of analytical grade 500ml, after a certain time, to generate an amino acid having umami, and then caustic soda (or soda ash) in analytical grade and sulfuric acid, to obtain sodium amino acids. MSG manufacturing principles with this almost. Industrial production method industry mainly by electrolysis 1, the saturated brine electrolysis, the divided sodium hydroxide, the hydrogen gas generated at the cathode, the anode to produce chlorine gas: 2NaCl + 2H2O == power == 2NaOH + Cl2 ↑ + H2 ↑ 2, the reactor will be in the hydrogen and chlorine through to quartz burner ignition and combustion, hydrogen chloride gas and emit a lot of heat: H2 + Cl2 == lit == 2HCl3, hydrogen chloride gas is cooled and water absorption becomes hydrochloric acid. During the reaction of chlorine and hydrogen gas, toxic chlorine gas is surrounded by an excess of hydrogen sulfate analytical 500ml, reaction of chlorine gas sufficiently to prevent the pollution of the air. In production, often taken as a raw material to make another approach allows excess harmful, more expensive raw materials adequate response.
