Characteristics: white crystals or crystalline powder, odorless having a peculiar sweetness. It readily solves in water, slightly in ethanol, does not solve in acetone or ethyl ether.
Usage: it is used as a flavoring or sweetness because it is sweet. In combination with sodium glutamate, dl-alanine, or citric acid, it can be used in alcoholic beverage; as a acid corrector or buffer for the composition of wine and soft beverage; as an additive for the making of salted vegetables and sweet jams; as an additive for the making of sauce, vinegar and fruit juice, in order to improve the flavor and taste of food, to retain its original color and to provide a source of sweet;
Package and transport: four-layer paper bags for the food grade, containing a net weight of 25kg /bag;

Product name: dl-methionine(acimetin)
Chemical formula: c5h11no2s
Quality standard: aji92
Charmacteristics and uses: white flaky crystal or crystalline powder. With special smell. Taste sweet. No optical activity. Stable to heat and air. Instability of the strong acid can lead to demethylation. Is a nutritional supplement.
Dl-methionine
Cas no: 59-51-8
Molecular formula: c5h11no2s
Molecular weight: 149.21
Product standard: aji-92/97 version, ep-4 version, usp-24/26 version, fcc-4 version
Properties: white flaky crystal or crystalline powder. Has special smell. Slight sweet taste. Melting point: 281 degree c(decompound). 10% aqueous solution's ph value is 5.6-6.1. No optical rotation, stable to heat and air. Unstable to strong acid, can cause the demethylation. Soluble in water(3.3g/100ml, 25degree c), diluted acid and diluted alkali solution. Very hard to dissolve in ethanol, almost does not dissolve in ether.
Use: dl-methionine is one of the basic units for composing the protein, is the only sulfur bearing amino acid among the essential amino acids, it participated in the transmethylation interior the animal body, the phosphorus metabolism and the adrenalin, choline and creatine synthesis, it also is the raw material of the protein and cystine synthesis. Methionine is unable to synthesize in the animal body, must take in from food. Adds it in the feed, can promote the poultry to grow, increase lean meat quantity and reduce the feeding cycle.
