Description

Five samples of cookie and cake which contain in different portions wheat flour, egg, sugar, butter and other ingredients were examined to determine the degree of gelatinization. The samples were prepared by baking, defatting-dehydration and de-proteining.<BR>The results were as follows : <BR>1) In preparation of samples the step of defatting-dehydration showed more significant influence on the degree of gelatinization than the step of de-proteining.<BR>2) The degree of gelatinization of starch from five samples was in the range of 9 to 11% for cookie, at about 56% for pound cake, at about 78% for sponge cake and at about 86% for angel cake.<BR>3) For de-proteining four methods were investigated, i. e., (1) sodium hydroxide, (2) toluenesodium chloride, (3) N, N-dimethyl formamide, and (4) protease were added to defatted samples. Method (1) was superior to three other methods in effectiveness to de-protein and in obtaining steady values of a degree of gelatinization.<BR>4) There was a high correlation (r=0.998) between the degree of gelatinization and the water content of each sample.
