Abstract
Abstract A process is provided for preparing a frozen whipped topping composition containing milk fat, which upon thawing, has an extended refrigerator shelf life while maintaining its volume, texture and eating properties. The process involves blending milk fat, emulsifier, stabilizer, carbohydrate and water with a cross-linked and hydroxypropylated starch, followed by pasteurizing, homogenizing, cooling, whipping and freezing the composition.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
162 words
Process for preparing a frozen whipped topping composition containing milk fat and having extended stability upon thawing and refrigerated storage by retaining its volume and smooth, continuous and fluffy texture comprising: (a) blending into a mix 15 to 30% by weight of a milk fat, 15 to 35% by weight of a carbohydrate, 0.2 to 2.0% by weight of an emulsifier, 0.02 to 0.2% by weight of a stabilizer, 35 to 65% by weight of a water and an amount of a crosslinked and hydroxypropylated starch effective to impart extended refrigerated storage stability; (b) solubilizing and dispersing the mix by subjecting the mix to heat; (c) homogenizing said mix at pressures of at least 6,000 p.s.i. to form an emulsion; (d) cooling said emulsion to a temperature and for a period of time effective to allow the fat to crystalize; (e) whipping and aerating said cooled emulsion to an overrun of at least 200% by volume; and (f) freezing said whipped emulsion.
