<p>The invention relates to products and processes for employing heat stable enzymes especially--although not exclusively--for retarding the staling of baked and leavened cereal products. A concentrated protective sugar medium is used to solubilize or disperse a fungal alpha amylase enzyme before it is incorporated in a dough. This medium protects the enzyme against thermal denaturation, thereby enabling the enzyme to remain active during baking and until the starch of the dough becomes gelatinized and subect to enzyme attack. A preferred embodiment of the dough also includes chemical emulsifiers which may be used in conjunction with the fungal alpha amylase enzyme dispersed in the concentrated sugar solution. The invention addresses the conflicting requirements that enzyme activity must continue as long as possible throughout the baking process to retard staling; however, all activity must terminate before the end of the baking process to prevent the dough from becoming a sticky mass or paste.</p> |
