    摘要: Breakfast cereals are sweetened by treating cereal grains or at least one cereal grain fraction such as bran, with enzymes comprising glucoamylase and glucose isomerase to produce fructose while retaining cereal particle discreteness or integrity. Enzymatic treatment with alpha-amylase may be initiated prior to, during, or after cooking. The enzymatically treated, cooked cereal grains are formed into breakfast cereal shapes and the enzymes are inactivated to provide a shelf-stable cereal product. The cereal products exhibit a sweet, pleasing complex-honey-like taste and aroma. Producing fructose provides a greater level of sweetness for a given amount of starch conversion into low molecular weight reducing sugars such as mono- and di-saccharides. In achieving a given level of sweetness, more starch or high molecular weight dextrins may be retained for their matrix forming ability or for improved machineability of the enzymatically treated cereal grains into breakfast cereal shapes. The naturally sweetened cereal products of the present invention may be in shredded, flaked, ground, or extruded form.

    摘要: A process is described which is useful as a co-process in combination with a process which employs hydrogen peroxide. The process of the invention provides a source of hydrogen peroxide along with a useful co-product, that co-product being 2-keto-D-gluconic acid or products derived therefrom. One of the first and second carbons of D-glucose is oxidized enzymatically to produce hydrogen peroxide and an intermediate product. The other of the first and second carbons of the intermediate product is then oxidized enzymatically to produce hydrogen peroxide and 2-keto-D-gluconic acid. In one form of the invention, the intermediate product is D-glucosone; the final product is 2-keto-D-gluconic acid. In the other form of the invention, the intermediate product is D-glucono-.delta.-lactone; the final product is a mixture of 2-keto-D-gluconic acid and D-isoascorbic acid.
