QUALITY DETERIORATION SUPPRESSED FOOD MADE BY USING WHEAT FLOUR PREPARED FROM WHEAT DEFICIENT IN ENZYMATIC ACTIVITY OF TWO GBSSI AND TWO SSIIa

摘要

PROBLEM TO BE SOLVED: To provide a novel means, for processed wheat food made by using wheat flour or starch as raw materials, that can improve the food taste and food texture after storage better than the conventional food product.SOLUTION: Provided is a quality deterioration suppressed processed wheat food made by using, as the raw materials, wheat flour obtained by milling harvest of wheat, 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. According to the invention, by using the wheat flour or starch derived from the wheat comprising a particular enzymatic deficiency pattern, the processed wheat food shelf life is enhanced, the quality deterioration is suppressed, and the food taste and food texture after refrigeration or storage at ordinary temperature is improved.
