Composition containing S-adenosyl-L-methionine with excellent storage stability
The present invention relates to a composition including S-adenosyl-L-methionine; and at least one kind of additive selected from carboxymethylcellulose, hydroxypropylcellulose, soybean polysaccharide, casein sodium, and zein, in which S-adenosyl-L-methionine is extracted from S-adenosyl-L-methionine-containing cells obtained by culturing a microorganism having an ability to produce SAMe, and the content of the additive in the composition falls within the range of 0.05 to 15 times by mass of S-adenosyl-L-methionine in the composition. The present invention provides a composition containing a high concentration of S-adenosyl-L-methionine, which is useful as a water-soluble physiologically active substance, and being excellent in storage stability and bioabsorbability. The present invention also relates to a molded article formed by using the composition and a method of producing the composition.
1. A composition comprising, in admixture:
a microorganism cell extract comprising S-adenosyl-L-methionine; and
at least one additive selected from the group consisting of soybean polysaccharide, casein sodium, and zein,
wherein:
the microorganism cell extract comprising S-adenosyl-L-methionine is extracted from an S-adenosyl-L-methionine-containing cell obtained by culturing a microorganism having an ability to produce S-adenosl-L-methionine;
a content of the S-adenosyl-L-methionine in the composition is in a range of 3% to 18.8% by mass, based on the dry mass of the composition;
a content of the additive in the composition is in a range of 0.05 to 15 times by mass of the S-adenosyl-L-methionine in the composition; and
the admixture of the microorganism cell extract comprising S-adenosyl-L-methionine and the at least one additive is produced by mixing the microorganism cell extract comprising S-adenosyl-L-methionine and the at least one additive.
