味精生产(Monosodium glutamate production)
味精生产(Monosodium glutamate production)
1 introduction of monosodium glutamate production process
Monosodium glutamate production is generally divided into sugar, glutamic acid fermentation, neutralization and extraction and refining
And so on 4 main processes.
1.1 liquefaction and saccharification
At present, most monosodium glutamate plants use starch as raw material because of the rising price of rice
Material. The starch must pass through the liquefaction stage. Then, with B, amylase acts into the sugar
Chemical stage. Firstly, a amylase starch liquefaction, and reduce the viscosity of starch
Hydrolyzed to dextrin and oligosaccharide, the content of protein in starch should be lower than the original
Therefore, the liquefied mixture can be directly added into the saccharifying enzyme to enter the saccharifying stage
Rather than using rice as raw material, it needs to be filtered through a basket filter press after liquefaction
A lot of protein precipitation. In addition to adding amylase to the liquefaction process, calcium chloride is added,
The total liquefaction time is about 30min. After a certain temperature liquefaction of dextrin and oligosaccharides in
The saccharification tank is further hydrolyzed to glucose. After the starch slurry is liquefied, it is cooled down by the cooler
The temperature is up to 60 DEG C and enters the saccharifying pot. Saccharification temperature control in
60 degrees Celsius, pH value of 4.5, saccharification time 18-32h. Saccharification will be finished after saccharification
The tank was heated to 8085 DEG C and the enzyme 30min was inactivated. Filtered glucose solution; filtered
After the machine, oil and water separation (one cold separation, two cold separation), and then filtered, continuous elimination
Enter the fermenter after poison.
1.2 glutamic acid fermentation
The glutamic acid culture medium was injected into the glutamic acid fermentation tank under the flow control, and the temperature was cooled to 32 DEG C
