MSG factory process design, MSG production design process

Can you choose the first floor.

The production of monosodium glutamate is generally divided into several main processes, such as saccharification, fermentation, extraction of glutamate crystals, and refining of sodium glutamate crystals.

The main components of monosodium glutamate are monosodium salt of monosodium glutamate C5H8NO4NA, L-2-aminoglutarate. Glutamate is one of the amino acids for oxidative metabolism in brain tissue, and MSG also contains a small amount of sodium chloride.

Users need to pay attention to the saltiness when stir-frying. If it is too salty, MSG may not be able to taste umami, and the ratio of salt to MSG is 3:1 or 4:

1 range, you can achieve a mellow and soft taste, when making cold dishes, it is advisable to dissolve before adding. Because the dissolution temperature of monosodium glutamate is 85, below this temperature, it is difficult for monosodium glutamate to decompose.

The production of monosodium glutamate is generally divided into four main processes: sugar refining, glutamate fermentation, neutralization extraction and refining.

First: the production of monosodium glutamate generally adopts the double enzymatic sugar method of medium-temperature amylase or high-temperature amylase liquefaction and high-conversion liquid saccharification enzyme saccharification. The conversion rate of amylase and the quality of the sugar solution are higher than those of the previous acid process or acid enzymatic process, especially the new double enzymatic sugar production process using high-temperature resistant amylase liquefaction.

Second, starch is liquefied by amylase to produce dextrin, and then dextrin is converted into glucose by saccharifying enzyme. The product obtained by enzymatic sugar method can be called enzymatic sugar solution to distinguish it from hydrolyzed sugar solution such as acid method.

The hydrolysis tank made of stainless steel has high mechanical strength, can resist acid and alkali, and has a long service life, but the cost is high. The advantages of the enamel hydrolysis tank (enamel lining) are that it has good corrosion resistance, resistance to concentrated hydrochloric acid and high temperature resistance of 150, but the disadvantage is that it is brittle, easy to break if it is impacted and cannot be welded on enamel equipment.

Third: the advantages of the pressurized saccharification tank lined with acid-resistant bricks and acid-resistant rubber are that it can withstand greater pressure, heat resistance, acid resistance, and good mechanical strength. Fermentation fed-added aseptic concentrated sugar, and the sterilized sugar solution was prepared into the form of monosodium glutamate.

3D printing technology can print out the production process and equipment, and you can understand the production process more intuitively. Adjacent 3D has done something similar.

Monosodium glutamate. It is fermented through grain and food, grain-starch-glutamic acid-sodium glutamate.

Monosodium glutamate. In the case of corn, corn starch is extracted from corn, and then saccharified and fermented into glutamine-type segmentic acid, which is then made into monosodium glutamate. After monosodium glutamate is made, it is processed through a series of treatments such as purification, and then monosodium glutamate is formed.

MSG is mainly extracted from rice, corn and other grains or molasses, using the method of biological fermentation of microtrabeculars. The main ingredient of monosodium glutamate is the sodium salt of glutamic acid, which is also the trade name and common name of monosodium glutamate, also known as flavor powder, Ajinomoto, sodium glutamate, and sodium glutamate. Monosodium glutamate participates in the normal generation of protein in the human body and promotes the oxidation process.

Glutamic acid is produced from saccharides or Dianfengdan powder raw materials, and then glutamic acid is extracted by isoelectric point crystallization precipitation, ion exchange or zinc salt refining, and then crystallized by decolorization, deironization, evaporation, silver selling and crystallization and other processes to make sodium glutamate crystals.
