Embodiment 1

[0036] Carry out fermentation with glucose as raw material, wherein the glucose is 1 ton, then add liquid ammonia and sodium carbonate solution to the fermentation broth, the molar ratio of liquid ammonia and sodium carbonate is 2:1, and obtain a pH of 6.9 containing sodium glutamate The fermentation liquid of the crude product, the two are added at the same time to obtain the fermentation liquid containing the crude product of sodium glutamate, and then the fermentation liquid containing the crude product of sodium glutamate is filtered through a plate frame or a micromembrane to remove bacterial protein and the micromembrane The pore size is 0.04 μm, centrifuged at 2000 r / min for 3 minutes, and the sterilized liquid is collected. The sterilizing solution is pumped into the decolorizing tank for decolorization treatment, and powdered activated carbon with a mass of 1.5% of the sterilizing solution is added to the decolorizing tank, the temperature in the decolorizing tank is c...

Embodiment 2

[0054] Take the waste water from the fermentation workshop of Fufeng monosodium glutamate production, and enter the sewage treatment system according to the method of Example 1. Use a 50L bucket as the test equipment with stirring. Take 30L respectively and add them to two buckets. Adjust the pH to 7.0 and the water temperature to 20°C , sampling measurement COD, ammonia nitrogen, total nitrogen data; The control group does not add composite bacterial agent, and experimental group adds compound bacterial agent in embodiment 1, adds 20 grams of microbial preparations at every turn by every cubic meter of still bottom material, and every day adds 1 After one week of continuous dosing, samples were taken to measure COD, ammonia nitrogen, and total nitrogen data. The treated wastewater fully met the discharge standards, as shown in Table 1:

[0056]

Embodiment 3

[0058] The probiotic effect test prepared by embodiment 1:

[0059] Duroc

[0060] The control group drank tap water; the test group drank 1% probiotic aqueous solution (weight ratio), with an average initial weight of 24.2kg,

[0061] The test group and the control group used 20 pigs each, divided into random groups, and raised them under the same conditions for 98 days. The growth conditions are shown in Table 2:

[0062] Table 2: Comparison of weight gain in pigs with probiotics

[0063] group

[0064] The data in Table 2 show that the growth ability of the pigs in the experimental group was significantly higher than that in the control group. During the breeding period, the occurrence of diarrhea, constipation and other digestive tract diseases in the experimental group was significantly reduced, and the odor of feces was also significantly reduced. The number of mosquitoes and flies was also less than that in the control group, and the economic benefits were ob...

Abstract

The invention relates to an environmentally friendly process for cleanly producing sodium glutamate, which includes the following steps: simultaneously adding liquid ammonia and sodium carbonate to glutamic acid fermentation liquid for reaction to obtain crude fermentation liquid; filtering through micromembrane, collecting and sterilizing liquid, and bacterial protein; bacterial protein is used to prepare probiotics, the sterilizing liquid is pumped into a decolorization tank for decolorization, and concentrated and crystallized to obtain crude sodium glutamate crystals; then the wastewater is refined and treated. The process of the present invention is economical and environmentally friendly. It has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of extracting sodium glutamate in the biological fermentation industry, and specifically provides an environmentally friendly process for cleanly producing sodium glutamate. Background technique [0002] The chemical name of sodium glutamate is monosodium α-aminoglutarate, which is a salt formed by sodium ions and glutamate ions, in which glutamic acid is an amino acid and sodium is a metal element. The main ingredient of seasoning MSG commonly used in life is sodium glutamate. Monosodium glutamate is a commonly used flavoring agent in daily life, which can increase the umami taste of food and help improve the digestibility of food by the human body. In addition, sodium glutamate has very important functions and is widely used in food, medicine, industry and agriculture. [0003] The following problems exist in the production process of sodium glutamate at present: [0004] On the one hand: during the fer...
