Description
Technical field
It is food industry the present invention relates to technical field, and in particular to a kind of glutami acid fermentation liquor prepares the side of sodium glutamate
Method.
Background technology
Sodium glutamate is commonly called as monosodium glutamate, scientific name monosodium glutamate (Monosodium Glutamate, referred to as MSG).
Sodium glutamate is a kind of important food additives, can enrich and improve the flavor of food, is widely used in food and food adds
Industrial and commercial bank's industry.China is sodium glutamate big producer, and annual production is close to 2,000,000 tons.Sodium glutamate is important tasty agents, to perfume (or spice)
Taste has humidification.Sodium glutamate is widely used in food flavor, both can be used alone, and and can and other amino acid etc. are simultaneously
With.It is continuously increased with the continuous development of biotechnology and to sodium glutamate demand, the yield of sodium glutamate is year by year
Improve, sodium glutamate turns into the first big fermented product.The existing production of sodium glutamate is using first from monoammonium glutamate zymotic fluid point
From glutamic acid semi-finished product, carry out neutralization with NaOH or Na2C03 and be converted into sodium glutamate, through decolourizing, concentrating, refined form paddy ammonia
The technique of sour sodium.Therefore, it is necessary to complete in extraction process：The product of monoammonium glutamate-glutamic acid-sodium glutamate is transformed
Journey.This conversion process needs to consume substantial amounts of soda acid, and production cost improves, and can cause substantial amounts of environmental pollution.Current
Research is concentrated mainly in the improvement of yield and extraction process, does not solve the problems such as cost is too high, seriously polluted from basic.
Sodium glutamate is refined by the glutamic acid (claiming bran acid) of fermentation extraction, and subtractive process is that glutamic acid is molten
Solution, neutralized with sodium carbonate, decolourized, condensing crystallizing, being dried to obtain finished product sodium glutamate.China mainly produces paddy ammonia with amylofermentation
Acid, ammonia is constantly added during the fermentation and maintains the pH of zymotic fluid to maintain 7 or so, gained zymotic fluid is monoammonium glutamate.Hair
After ferment terminates, glutamic acid is extracted using isoelectric point crystallization step, i.e., adjusts the pH of zymotic fluid to the isoelectric point of glutamic acid with the concentrated sulfuric acid
Make glutamic acid crystallization (referred to as " isoelectric point crystallization ").The glutamic acid crystal isolated through refined (dissolving, neutralize, decolourize, crystallization) and
Into sodium glutamate.Isolate the remaining supernatant of glutamic acid crystal and be referred to as " waiting electric mother liquor ".Current industrial production generally use
" isoelectric point crystallization, ion exchange " technique (as shown in Figure 1), remaining glutamic acid is extracted from grade electric mother liquor with ion-exchange,
Ammonium root containing 15-20g/L glutamic acid, 30-40 g/L sulfate radical and 10-15 g/L in its medium electric mother liquor, pH are about
3.0.Another technique " concentrate-waiting electricity " technique (as shown in Fig. 2) that industrial production uses either " wait electricity-from hand over " work
Skill obtain from handing over waste liquid, what the technique that still " concentrate-waits electricity " obtained wait electric mother liquor, sulfate radical and ammonium containing high concentration,
It can encounter problems with existing processing method.For example, during with bio anaerobic and Aerobic Process for Treatment, can be pressed down by high-concentration sulfuric acid ammonium
System；Ammonium sulfate is also difficult to degrade in itself；During for culture yeasts, suppressed by high-concentration sulfuric acid ammonium, the growth rate of yeast is low；And
When being concentrated to produce sulfuric acid ammonium compound fertilizer or crystalline sulfuric acid ammonium, energy consumption is excessive, causes secondary pollution.In summary, it is existing
Sodium glutamate production technology all have passed through extraction stage of glutamic acid, long flow path, step is more, also produces a large amount of waste liquids.Therefore,
The method that monosodium glutamate is directly produced from glutami acid fermentation liquor is described in patent CN 102126979.A, this method is using electricity
Dialysis method directly produces monosodium glutamate from glutamic acid (ammonium) zymotic fluid, it is possible to reduce sodium glutamate production stage, reduces life
Cost is produced, discharging of waste liquid is reduced, realizes clean manufacturing.Meanwhile by-product ammonium chloride, ammonium sulfate or ammonium nitrate are obtained.
The content of the invention
