In medicine, can be used for the treatment of heart disease, liver disease, hypertension, with the prevention and recovery of fatigue, and a variety of amino acids together, made of amino acid infusion, used as ammonia antidote, liver function promoter, fatigue recovery agent. In the food industry, is a good nutritional supplements, added to a variety of cool drinks; Also Sweet (aspartame)-aspartame-the main raw material of methyl aspartate. In the chemical industry, can be used as a raw material for the manufacture of synthetic resin. It can also be used as a nutritional additive for cosmetics. nutritional supplements. Co-heating with sugar for amino-carbonyl reaction, can form a special flavor substances. For cool drinks. used in biochemical research, used to treat myocardial infarction, myocardial metabolic disorders, heart failure, heart block, fatigue and other symptoms. amino acid drugs. used as biochemical reagents used in the synthesis of organic raw materials or pharmaceutical intermediates biological culture, peptide synthesis, detection of chlorine enzyme substrate, tuberculosis culture, treatment of acrylonitrile wastewater, preparation of biological medium. |
| production method | White Lupine as raw material, after germination, slurry, heat treatment, under the condition of pH less than 6, the crude product is obtained by diatomite filtration and centrifugation, and then concentrated and crystallized to obtain the finished product. isolated from an aqueous extract of bean sprouts of Lupin and soybean having a high L-asparagine content. Obtained by amidation of L-aspartic acid with ammonium hydroxide. |
