Abstract:
The present invention provides a stable fat-soluble active ingredient composition, microcapsule and process for preparation and use thereof. The fat-soluble active ingredient composition comprises tocopherol, vitamin C palmitate and a fat-soluble active ingredient; wherein the weight ratio of tocopherol to vitamin C palmitate is 2-8:1, the weight ratio of a combination of tocopherol with vitamin C palmitate to the fat-soluble active ingredient is 7-13:100. The present invention obtains a novel antioxidant composition without hidden dangers for improving the stability of the fat-soluble active ingredient by screening a combination of antioxidants and adjusting their proportion and dose.

Claim (Index 9):
A process of preparing the fat-soluble active ingredient microcapsule according to  claim 8 , comprising the following steps:\n 1) blending and melting a fat-soluble active ingredient with an antioxidant in a certain weight ratio at temperature of 45-85\u00b0 C. under nitrogen protection to form an oil phase A of a fat-soluble active ingredient molten oil; wherein the antioxidant is tocopherol and vitamin C palmitate, the fat-soluble active ingredient is selected from at least one of the group consisting of vitamin A, vitamin D, vitamin K, coenzyme Q10, carotenoid and polyunsaturated fatty acid and ester thereof; 2) dissolving a gelatin or a modified starch as a low molecular filler and a glucose or a white sugar in water at 60-70\u00b0 C. under nitrogen protection, to obtain an aqueous phase B; 3) blending the oil phase A of step 1) with the aqueous phase B of step 2) under nitrogen protection, and then high-speed shear emulsifying, degasifying and homogenizing under nitrogen protection in closed conditions, to obtain an emulsion; and 4) spraying granulation the emulsion of step 3), and then fluidizing drying, to obtain a fat-soluble active ingredient microcapsule.
