L-Alanine is a white and odorless crystal
powder with special sweet tasle, which degree
is about 70% of sugar. It easily dissolves in
water (17% under 25 ),
slightly dissolves in alcohol (0.2% in cold
alcohol) and unclissolves in ether. PH value
in 5% water solution equals 5.5 to 7.0.
2.Usage
L-Alanine is a kind of important amino
acid formed proteins. In medicine, it is a main
material syntheslsed VB6, composition of nutriments,
and important composition of 800-14 amino acid
injection new medicine for disease of liver
and brain. In food, it can be used as flavouring,

of organic acid. Also it can be used as additive
of salted food, drink cotained alcohlos, oil,
yolk sauce, and improving the taste of food
made with dregs of rice.
