    摘要: An amorphous sialic acid powder is disclosed. It is prepared by rapidly freezing an aqueous solution of sialic acids and freeze-drying the frozen product. It has a melting point of 131.degree.-136.degree. C. (decomposed) and exhibits no peaks inherent to crystals in differential scanning thermal analysis (at 165.degree.-200.degree. C.) and X-ray diffractiometric pattern (in the range of 5.degree..ltoreq.2.theta..ltoreq.40.degree.). The amorphous sialic acid powder is highly reactive and can be used as a raw material for drugs and the like.

    摘要: An L-carnitine agent has an indispensable function in the body and utility as a material for pharmaceutical agents or food and drink. By subjecting milk or modified milk products of mammals from which casein is removed, to the treatment of desalting and partial removal of lactose followed by drying, L-carnitine content, lactose content, and ash content are adjusted to 0.1˜100 mmol/100 g, 20˜95 g/100 g, and 5 g/100 g or less, respectively.
