摘要:
A feed additive composition includes a protective agent, lecithin, an acidic or neutral amino acid, and water. A method of producing a feed additive composition includes preparing a molten mixture of a protective agent, lecithin, and an acidic or neutral amino acid, and immersing the molten mixture in water or an aqueous liquid to obtain a solidified mixture. Feed additives may be obtained by such method. The protective agent may include a hydrogenated vegetable oil or hydrogenated animal oil having a melting point of higher than 50° C. and lower than 90° C.

A feed additive composition includes a protective agent, lecithin in an amount of 0.05 to 6% by weight relative to a total weight of the composition, a basic amino acid in an amount of at least 40% by weight and less than 65% by weight relative to the total weight of the composition, and water. A method of producing a feed additive composition includes preparing a molten mixture of at least one protective agent, lecithin and at least one basic amino acid, and solidifying the molten mixture by immersing the molten mixture in water or an aqueous liquid. The protective agent includes hydrogenated vegetable oils and/or hydrogenated animal oils having melting points of greater than 50° C. and less than 90° C.

A food additive composition for ruminants of the dispersion type and a method of continuously producing the same. This food additive composition for ruminants, which contains 40% by weight or more but less than 65% by weight of a basic amino acid and has rumen bypass properties, is formulated into granules in an arbitrary shape which are scarcely classified when added to a silage or another feed. Thus, attempts have been made to develop a method of producing granules by which the milk yield of a lactation cow can be increased. Namely, it is intended to provide a food additive composition for ruminants which contains at least one protecting agent selected from among a hardened vegetable oil and a hardened animal oil having a melting point higher than 50° C. but lower than 90° C., 0.05 to 6% by weight of lecithin, water and 40% by weight or more but less than 65% by weight of a basic amino acid. It is also intended to provide a method of producing a food additive composition for ruminants characterized by comprising solidifying a molten mixture, which comprises at least one protecting agent selected from among a hardened vegetable oil and a hardened animal oil having a melting point higher than 50° C. but lower than 90° C., lecithin and a basic amino acid, by dipping in water.
摘要:
2-Deoxy-L-ribose may be prepared by reacting a compound represented by formula (1) with an organometallic compound represented by formula (2) to give a compound represented by formula (3), which is then subjected to deprotection of a hydroxyl group and production of aldehyde by acid hydrolysis: wherein R1 and R2 are each independently a hydroxyl-protecting group or R1 and R2 in combination form a hydroxyl-protecting group, R3 and R4 are each independently an alkyl group, an aralkyl group, an aryl group or a silyl group or R3 and R4 in combination form an alkylene group.
摘要:
The present invention provides a production method of an optically active &bgr;-amino-&agr;-hydroxycarboxylic acid, which includes the following steps (a)-(c): (a) treating an optically active N-carbamate protected &bgr;-amino epoxide with an acid to give an optically active 5-hydroxymethyl-2-oxazolidinone; (b) oxidizing the resulting compound in the presence of 2,2,6,6-tetramethyl-1-piperidinyloxy and hypochlorite to give an optically active 4-benzyl-2-oxo-5-oxazolidinecarboxylic acid; and (c) treating the 4-benzyl-2-oxo-5-oxazolidinecarboxylic acid with a base, and a production method of an optically active N-carbamate protected &bgr;-amino-&agr;-hydroxycarboxylic acid which includes protection of the amino group with a carbamate type protecting group. The industrial production method of the present invention can produce these compounds efficiently.
