Abstract

Whole grain rice, either white or brown rice, is liquefied and treated with high levels of a glucosidase enzyme and/or a combination with beta-amylase enzyme in a saccharification step. Total enzymatic reaction time is limited to about four hours for both the liquefaction and saccharification steps combined to prevent the development of undesirable off-flavors. The product of the saccharification step is partially clarified to remove substantially all rice fiber, but not other nutritional values and then concentrated to produce a preferred rice syrup sweetener which is cloudy in character and has a solids composition defined as follows: PA1 Soluble Complex Carbohydrates--About 10 to 70% of solids; PA1 Maltose--About 0 to 70% of solids; PA1 Glucose--About 5 to 70% of solids; PA1 Ash or Minerals--About 0.1 to 0.6% of solids; PA1 Protein and Fat--About 1 to 3.5% of solids; The rice syrup sweetener of the invention can be dried to produce dried rice sweeteners.
