Amyloglucosidase (Novo 150 L. 5 mlilOO kg) used with optimum ct-amylase supplements [MSKB/100 g flour] of wheat malt, 7.5, fungal, 20. and bacterial, 0.4, increased the reducing sugars of sour doughs (pH 4.55. 3 h/30 "C) by 71.7 to 72.2, 94.0 to 103.1 and 71.7 to 77.0% as compared to 48.3 to 58.0, 61.1 to 71.3 and 7.3 to 12.0% of initial pH 5.8 doughs, respectively. Amyloglucosidase alone or with ct-amylase supplements had negligible effect on mixing properties of dough, falling number values and paste viscosities which were affected more by the wheat malt a-amylase. The combined enzymes had a beneficial effect on bread quality of the medium-protein flours without extraneous sugar in the formula.In the previous paper, HARINDER et al. [I] described the effect of cereal, fungal and bacterial a-amylase supplements on the rheological and breadmaking properties of mediumprotein flours. Accumulation of maltose in the bread crumb due to a-amylase action, was reported. Although, application of amyloglucosidase in fermentation industry and dextrose manufacturer is well established [2], its use in bread making has received scant attention [3] as compared to a-amylase supplements [l, 4, 51. The present investigation aimed at producing easily fermentable dextrose in the dough system using amyloglucosidase with and without cr-amylase supplements, and to evaluate the consequences of their interaction on the rheological and breadmaking properties of medium-protein flours. Experimental Amyloglucosidase (150 L )ICC method [7] after inactivation of the u-amylase in pH 4.2 solution at 60 'Cjl h. This was obtained from M/S Novo Industries, Denmark. Its activity (103 SKB/g) was determined by the u-amylase supplements Fungal ( A . oryzae) a-amylase (Fungamyl 180 S) with a designated activity of 4500 SKB/g was Novo brand. Bacterial (B. subtilis) a-amylase was supplied by M/S Schwarz/Mann, U.S.A., with a rated activity of 19900 SKB/g. Wheat malt with an activity of 100.9 SKB/g was prepared in the Laboratory. The a-amylase activities
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
