    • Phospholipo-proteins which have been enzyme modified may be used as an emulsifier to improve the emulsion stability of frozen products, e.g., during the freeze thaw and vacuum cool processes. Especially preferred is use of the enzyme phospholipase A to modify egg yolk and to use the modified egg yolk as an emulsifier in frozen products. Creation of a more stable emulsion can be expected to improve the overall appearance of the final product both in the frozen state and after the product has been reheated. Although egg yolk is preferred, examples of other phospholipo-protein containing substances include casein, skim milk, buttermilk, whey, cream, soybean, yeast, whole egg, blood serum and wheat proteins. Egg yolk and/or other sources of phopholipo-protein can be subjected to the action of phospholipase A or other enzyme, and then the modified product incorporated into the products of the invention. Alternatively, it is possible to isolate the phospholipo protein from its source and subject the isolated protein to the action of phospholipase A, after which the modified phopholipo-protein is incorporated into the frozen food products of the invention.
    • 已经酶修饰的磷脂蛋白可以用作乳化剂,以改善冷冻产品的乳液稳定性,例如在冻融和真空冷却过程中。 特别优选使用磷脂酶A来修饰蛋黄,并使用改性蛋黄作为冷冻产品中的乳化剂。 可以预期产生更稳定的乳液可以在冷冻状态下和在产品再加热之后改善最终产品的整体外观。 虽然蛋黄是优选的,但其它含磷脂蛋白质的物质的实例包括酪蛋白,脱脂乳,酪乳,乳清,奶油,大豆,酵母,全蛋,血清和小麦蛋白。 蛋黄和/或其他来源的磷脂蛋白可以进行磷脂酶A或其他酶的作用,然后加入到本发明产品中的改性产品。 或者,可以从其来源分离磷脂蛋白并将分离的蛋白质分离到磷脂酶A的作用,之后将修饰的磷脂蛋白掺入本发明的冷冻食品中。
