CHROMIUM-METHIONINE CHELATE, PRODUCTION METHOD THEREOF, AND FEED ADDITIVES CONTAINING THE SAME

摘要

PURPOSE: Chromium-methionine chelate, a production method thereof, and feed additives containing the same are provided, thereby increasing the chromium absorption to domestic animals, so that the meat quality and weight of the domestic animals can be improved. CONSTITUTION: The method for producing the chromium-methionine chelate comprises the steps of: (1) adding distilled water into L-type methionine and dissolving methionine at 40 to 60 deg. C; (2) adding inorganic chromium into the dissolved methionine and mixing them; (3) adding alkali solution into the mixture in twice and mixing them; (4) cooling the mixture to 10 to 20 deg. C to form crystals, and crying the crystals; and (5) pulverizing the dried crystals, wherein the inorganic chromium is chromium chloride solution(CrCl3 6H2O); the alkali solution is NaOH solution; and the mole ratio of methionine and inorganic chromium is 2:1. The feed additives contain the chromium-methionine chelate as an effective component.
