Abstract: Provided is an ice cream or ice cream-like product, to which a good body, flavor and a smooth texture have been imparted, and a method for producing the same. In a process of producing an ice cream or ice cream-like product, a step, wherein a protein deamidating enzyme is added to a milk material or a liquid ice cream mix for treating the same to thereby deamidate milk proteins in the milk material, is employed.

Abstract: A fat-free or low-fat yoghurt having a rich and creamy texture like yoghurts produced using whole-fat milk may be produced by adding a proper amount of a milk protein, such as a defatted milk powder, that has been deamidated with a protein deamidating enzyme to a fat-free or low-fat raw material milk. Alternatively, a proper amount of a milk protein, such as a defatted milk powder, is added to a fat-free or low-fat raw material milk, and the resulting mixture is subjected to a deamidation treatment with a protein deamidating enzyme so that the deamidation ratio reaches a proper level. In this manner, a fat-free or low-fat milk raw material having a milk protein mass and a deamidation ratio both falling within proper ranges can be prepared, and yoghurt may be produced using the milk raw material.

Abstract: The present invention provides a processed food obtained by using a starch-containing raw material such as wheat flour as a starting material, which has an excellent color, gloss and texture and shows regulated degradation with the lapse of time after cooking, and a method of producing the same. In producing a processed food by using a starch-containing raw material as a starting material, a deamidated milk raw material obtained by treating a milk material with a protein deamidase is employed as a starting material.
