Frozen foods using wheat flour prepared from wheat lacking two GBSSI and two SSIIa enzyme activities

摘要

PROBLEM TO BE SOLVED: To provide a novel means, for a frozen food made by using wheat flour or starch as raw materials, that improves the texture of food after freezing and thawing better than the conventional frozen food.SOLUTION: Provided is a frozen food for non-heating thawing made by using, as the raw materials, wheat flour obtained by milling wheat harvest, or starch separated from the harvest or the wheat flour, that is deficient in enzymatic activity of any two of GBSSI-A1, GBSSI-B1 and GBSSI-D1, and that is deficient in enzymatic activity of any two of SSIIa-A1, SSIIa-B1 and SSIIa-D1. By using the wheat flour or starch derived from the wheat comprising the particular enzymatic deficiency pattern, the food texture of frozen food comprising processed wheat food after thawing can be improved better than the conventional frozen food.
