Preparations containing fat-soluble vitamins in dry, particulate, free-flowing form dispersible in cold water and method of producing such preparations

摘要

When producing preparations of fat-soluble vitamins in which the vitamins are dispersed into gelatinous particles by the known processes for this purpose, the gelatine used is partially decomposed by treatment for 0.1 - 2 hours with 0.05 to 0.5 g. equivalent of hydrochloric or sulphuric acid or sodium or ammonium hydroxide per 100 g of gelatine; the so treated product is neutralized with the same bases or acids as the case may be, and the vitamin is dispersed therein, to form particles of 1-5 mu diameter. The gelatine is divided to particles 50-400 mu in diameter and produced in particulate form in known manner. Because of the pre-treatment of the gelatine, the finished and dried product is cold water-soluble even at 0 DEG -7 DEG C.
