Abstract
Provided are a process for producing a S-adenosyl-L-methionine-containing composition which is very excellent in a stability by adding at least ascorbic acids or salts thereof to a composition liquid containing S-adenosyl-L-methionine and then drying the above composition liquid or separating and drying a crystallized deposit obtained from the above composition liquid, a S-adenosyl-L-methionine-containing composition obtained by the above production process and a molding obtained from the above composition.
Claims5
A production process for a S-adenosyl-L-methionine-containing composition, comprising adding sulfuric acid or a salt thereof, p-toluenesulfonic acid or a salt thereof and sodium L-ascorbate to a composition liquid containing S-adenosyl-L-methionine, and then drying the above composition liquid or separating and drying a crystallized deposit obtained from the above composition liquid, wherein an amount ratio of sodium L-ascorbate to S-adenosyl-L-methionine contained in the S-adenosyl-L-methionine-containing composition obtained falls in a range of 0.2 to 1.4 times mole.
A process for producing a stable S-adenosyl-L-methionine-containing composition, comprising adding sulfuric acid or a salt thereof, p-toluenesulfonic acid or a salt thereof and sodium L-ascorbate to a composition liquid containing S-adenosyl-L-methionine, and then drying the above composition liquid or separating and drying a crystallized deposit obtained from the above composition liquid, the stable S-adenosyl-L-methionine-containing composition being stable under accelerating conditions of 40° C. and a relative humidity of 75%, and wherein an amount ratio of sodium L-ascorbate to S-adenosyl-L-methionine contained in the S-adenosyl-L-methionine-containing composition obtained falls in a range of 0.2 to 1.4 times mole.
