Use
Disodium 2-aminopentanedioate is the most widely used flavor agent at home and abroad.
When Disodium 2-aminopentanedioate coexists with salt, it can enhance its flavor effect.
When Disodium 2-aminopentanedioate is used together with sodium 5 '-inosine or sodium 5'-guanosine, it has more multiplication effect.
China's regulations can be used in all kinds of food according to the production needs of the appropriate amount.
Used as food flavoring agent.
Disodium 2-aminopentanedioate is a very mild cleansing agent that lathers slightly.
Disodium 2-aminopentanedioate is derived from coconut fatty acid and glutamic acid, an amino acid.
Disodium 2-aminopentanedioate can be found in cleansers, acne products, body gels, and shampoos.
Disodium 2-aminopentanedioate is a magical ingredient that is light on skin and hair, while also providing multiple benefits when added to the formulations.
Disodium 2-aminopentanedioate is used in a range of products such as shampoos, toothpaste, liquid soaps, etc.
Skin care: Disodium 2-aminopentanedioate is a cleansing agent and a good emulsifier that leaves the skin gentler, cleaner, conditioned and smoother without being too harsh.
This ingredient is effective for sensitive or oily skin types.
Hair care: Disodium 2-aminopentanedioate has foaming qualities to it.
When in formulations, Disodium 2-aminopentanedioate forms a rich lather that feels good and does not irritate the hair or scalp.
Disodium 2-aminopentanedioate has a stabilizing effect on the bubbles, which means that they last longer before breaking down.
Production Method
At present, rice, starch or molasses are used as raw materials to prepare: starch saccharification.
The saccharification of starch is mostly by double enzyme method.
Rice is directly blended into starch slurry with relative density of 1.11(14 ° Bé) after soaking, sanding or starch, adding α-amylase to liquefy for 15-20min at PH4.5 and 90 ℃, then heating to 100 ℃ for 5min.
After feeding, the filter residue can be used as feed, β-amylase is added, and saccharification is carried out at 60 ℃ for 12h, after the temperature is raised to 100 ℃, the enzyme is killed and then cooled and clarified.
The supernatant liquid is directly put into the sugar solution storage tank.
The precipitate liquid is added with filter aid diatomite and then pressure-filtered.
The starch sugar conversion rate can reach 92%.
About 15% of glucose is used as the carbon source, and an appropriate amount of inorganic salt and biotin are added to form a fermentation medium.
After being eliminated and cooled to 40 ℃, it is sent to a sterilized fermentation empty tank, and the added liquid ammonia is used as the nitrogen source.
Inoculate glutamic acid-producing bacteria cultured by secondary expansion, ventilate and ferment for 30 hours, the sugar-acid conversion rate can reach 50%, and the acid production level is about 7.0%-7.5%.
The PH of fermentation process is controlled at 7.0-7.2, the temperature is controlled at 32-34 ℃ in the early stage and 34-37 ℃ in the later stage.
Extraction of glutamic acid.
The extraction of glutamic acid is now generally by freezing isoelectric-ion exchange method.
The fermentation broth is slowly stirred and cooled to 5 ℃ with frozen brine in an isoelectric tank, and the PH is adjusted to 3.22 (isoelectric point) with sulfuric acid.
After 8 hours of precipitation, the precipitate is centrifuged to obtain crude glutamic acid.
After the mother liquor and supernatant are mixed, the ion exchange resin is exchanged and washed with ammonia water.
The front stream is merged into the supernatant and then onto the column, and the back stream and ammonia water are used as eluent, the high fraction and the fermentation broth are returned to the isoelectric tank, and the extraction rate can reach 88%-90%.
glutamic acid refining.
Add glutamic acid to a neutralization tank filled with 60-65 ℃ bottom water, stir, and slowly add soda ash solution to neutralize until PH6.2-6.4, and the concentration of the neutralization solution is controlled at a relative density of 1.17-1.18(21-22 ° Bé); To be cooled to below 50 ℃, add an appropriate amount of sodium sulfide solution to remove iron, then use crude glutamic acid to adjust the PH to 6.2-6.4, and raise the temperature to 60 ℃, then add powdered activated carbon, after stirring for 0.5h, it is sent to a filter press for filtration, and then the filtrate is decolorized with a granular activated carbon column for the second time to obtain a clear liquid.
The clear liquid is sent to a vacuum crystal boiling pot and evaporated and concentrated to a relative density of 1.28(31.5 ° Bé) at 60-70 ℃.
0.36-0.542mm crystal seeds are added and then evaporated and crystallized.
During this period, hot water is used for crystal killing and a certain amount of clear liquid is added.
After discharging, crystallized monosodium glutamate is obtained, mother liquor or after decolorization and then evaporation and crystallization, the refining yield can reach 92% of the theoretical amount.
