Chinese Product Name: L-alanine
English Product Name: L-Alanine; L-α-Aminopropanoic acid
Chemical formula: C3H7NO2
Chemical Name:
Properties and uses: a white odorless crystalline powder. Special sweet, sweetness is about 70% of sucrose. 1.6 times for the glycine, the amino acids are the most sweet. In aquatic animals (shrimp, crab), the more content, and form a characteristic flavor component. Start sublimation above 200 ℃, melting point 297 ℃ (decomposition). On the thermal and chemical stability. Soluble in water (17%, 25 ℃), slightly soluble in ethanol (80% cold alcohol 0.2%), insoluble in ether. 5% aqueous solution of the ph value of 5.5 ~ 7.0. Purpose: to improve the sweetness and enhance a sense of mellow sweet degree, improve the effect of acid flu season, can increase salt products and Vinegar flavor chemicals, ease astringency, bitter, pungent flavor and prevent the aging of beer. Inhibited Escherichia coli, leather-type positive bacteria, lactic acid bacteria and aerobic microorganisms in the growth and development. Another isomer of L-β-alanine, has yet to report the existence and proteins, with the apple juice, the sweeter than α-small.
