PURPOSE:To provide the titled easily handleable powder having high stability and water dispersibility, by heating a solution containing a sugar composition of maltose and an oligosaccharide at a specific concentration to effect the complete dissolution, cooling the solution, adding and emulsifying lecithin and vitamin A in the solution, and pulverizing the emulsion. CONSTITUTION:A sugar composition of (A) 5-50wt% of maltose or a saccharide composed mainly of maltose and (B) 50-95wt% of an oligosaccharide (e.g. sucrose, lactose, etc.) and/or hydrolyzed starch (e.g. dextrin, starch syrup, etc.) is added with water to adjust the solid sugar concentration of 30-85wt%. The mixture is heated at 90-150 deg.C to effect the complete dissolution of the saccharides, and the resultant sugar solution is cooled to 20-80 deg.C. Lecithin and vitamin A are added to the product, emulsified, and rapidly and efficiently dried to a water-content of <=5%. The obtained dried product containing vitamin A is pulverized to obtain the objective powder. The amount of lecithin is selected to give total phospholipid content of <=20%, especially 1-10% in the powdery vitamin A. |
