According to reports, MSG is a sodium salt of glutamic acid C5H8NO4Na
For a flavor of the material, learning called glutamate, also known as monosodium glutamate. In addition it also contains a small amount of salt, water, fat, sugar, iron, phosphorus and other substances. MSG is a flavor condiments cooking materials, wheat, soybeans and other protein-containing raw materials more available or by the hydrolysis method using starch as raw material made by a fermentation process or crystalline powder spices, sugar beet can also be used and honey produced by chemical synthesis. MSG soluble in water, with moisture absorption, very delicious taste, soluble in water 3,000 times still has flavor, the best solution temperature is 70 ℃ ~ 90 ℃. MSG in general more stable under the conditions of the cooking process, but for a long time at high temperature, easy to become a focus of sodium glutamate, no significant flavor and slightly toxic; in alkaline or acidic solution, precipitation or difficult to dissolve, and its flavor is not apparent or even disappear. It is not only increase people's appetite, but also provide a nutritious homemade condiments.
First, the production scale of monosodium glutamate factory
The production scale of monosodium glutamate factory mainly determined by the market, followed by construction traffic, transportation, water, electricity, raw materials supply, sewage treatment and so on. The market share is determined by the brand and production costs, mainly the latter. As long as the low cost of production, market development has the potential, we can expand the production scale.
1. MSG production profile
At present, the production of glutamate monosodium glutamate factory about 50 (to buy other than glutamic acid system MSG), MSG production of goods in 2002 about 90 million tons, than 100 million tons this year. MSG basic balance of the current sales. The first half of this year due to "atypical pneumonia" effect, MSG weak market, product backlog, but the second half of the sales situation is quite good, basic balance production and sales. In the future, due to China's economic development and better living standards improve, a large number of rural surplus labor into the city, the entire food industry situation, the condiment production increases, also increasing demand for MSG, but MSG production development too fast, This is the manufacturer must see, can not be blind expansion.
MSG market, there is a strange phenomenon, that is, too-packing business, all small private enterprises, most of these people had in the MSG industry work, they occupy a certain market, but also in the capital, sales taxes and so are the means and flexibility with advantage. And some of the new northern extension of the MSG MSG plant or plant due to lack of market, selling a large number of large packages, but also to provide favorable conditions for repackaging and therefore, packaging and business teams will be expanded.
MSG manufacturer to win the competition in the market, not to be eliminated, we must do everything possible to play to their strengths, improve skills, reduce production costs.
2. Production scale
Scale of production depends on the market, and market share mainly determined by the cost of production. The cost of production depends mainly on the following four aspects: ① regional advantages (including raw materials, power prices and local policies, etc.); ② technical level and management level; ③ scale (in the small scale of production, such as the annual output of 2 million tons below increase productivity, decrease costs, but production is large, has little effect); ④ operating costs (depending on equipment design, equipment and technology management, etc.).
Dominant is difficult to change, when a further expansion of large scale production has little effect on production costs. Production costs should begin construction, attention to rational design of equipment, equipment for reasonable conduct, the combination of production scale and size of equipment, reduce operating costs; selection of advanced production technology and strengthen the technology management, improve the technological level and reduce consumption.
Second, the size and number of fermentation equipment
Scale fermentation equipment refers to the size of the volume of fermentation, in considering the volume of the fermentation tank size, must also consider the number of fermentation tanks. Fermentation tanks from a single point of view, large volume, production is easy and stable, high fermentation, glutamic acid per ton of theory of low power consumption, the operator less. However, the number of too little fermentation tank, water, electricity, steam, sterile air, power consumption imbalance, running costs high. The fermentation tank of about 10 for a combination of the lowest operating costs. Raw material input, power consumption, the most stable, balanced, management, operations staff at least.
Third, the fermentation process selection
Currently being used in a fermentation process of glutamate amount of biotin Asia, high biotin added penicillin and surface active agents, such as the three temperature-sensitive, these three characteristics of the fermentation process, fermentation technology, extraction methods and yield , the main raw materials, electricity, gas consumption see table.
Can be seen from the table, its advantages and disadvantages of three fermentation process, a single point of view from the fermentation technology for high-temperature-sensitive, select the fermentation process should be based on the specific circumstances of manufacturers, such as the use of raw materials, fermentation equipment, the extraction process, water, electricity, and sewage treatment and other conditions to decide. No matter what kind of process must be to achieve greater efficiency, lower consumption, lower costs, and not a one-sided pursuit of a high index. If the high consumption, high production costs, is high in some indicators is not useful, comprehensive benefits must be considered.
I think we should draw on the advantages of the process and overcome its shortcomings, can raise the level of fermentation, but also high yield by extraction of the extraction process, to further improve the efficiency of glutamate production, which is the direction of glutamic acid fermentation.
