Abstract
Abstract A vitamin E dry powder, which contains a protein colloid and a disaccharide as carriers, is prepared by dispersing a vitamin E ester in a residual liquor, low in alkaline earth metal ions and rich in lactose, from the production of lactose, in the presence of from 2 to 30% by weight, based on the solids content of the residual liquor, of a caseinate, and spray-drying the dispersion. The vitamin E dry powder thus prepared is stable, easy to dose and physiologically safe, so that it can be used for any desired purpose.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
A process for preparing a vitamin E powder containing from 10 to 60% by weight of vitamin E acetate which process consists essentially of (a) dissolving sodium or potassium caseinate in a residual liquor from the production of lactose, which liquor contains from 10 to 35% by weight lactose and, apart from 0.5 to 1.0% by weight of nitrogenous substances and from 0.1 to 3.0% by weight of mineral salts, only traces of other constituents originating from milk, the amount of caseinate in said solution being from 2 to 30% by weight; (b) mixing oily vitamin E acetate and said solution in a pressure homogenizer whereby a dispersion of vitamin E acetate in said solution is formed, the amount of vitamin E acetate mixed with the solution being sufficient to produce a final product containing from 10 to 60% by weight of vitamin E acetate; and thereafter (c) spray-drying the dispersion to form a powder containing lactose, sodium or potassium caseinate and vitamin E acetate.
Claim 2
Dependent Claim
165 words
A process for preparing a vitamin E powder containing from 10 to 60% by weight of vitamin E acetate which process consists essentially of (a) dissolving sodium or potassium caseinate in a residual liquor from the production of lactose, which liquor contains from 10 to 35% by weight lactose and, apart from 0.5 to 1.0% by weight of nitrogenous substances and from 0.1 to 3.0% by weight of mineral salts, only traces of other constituents originating from milk, the amount of caseinate in said solution being from 2 to 30% by weight; (b) mixing oily vitamin E acetate and said solution in a pressure homogenizer whereby a dispersion of vitamin E acetate in said solution is formed, the amount of vitamin E acetate mixed with the solution being sufficient to produce a final product containing from 10 to 60% by weight of vitamin E acetate; and thereafter (c) spray-drying the dispersion to form a powder containing lactose, sodium or potassium caseinate and vitamin E acetate.
Claim 3
Dependent Claim
24 words
The process of claim 1, wherein the caseinate is dissolved in the lactose-rich residual liquor while maintaining the pH at from 6 to 8.
