Publication number: 20210196804Abstract: Sucrose isomerase is used as a nutritional supplement, or can be mixed in with a powderous food/beverage formulation. When an animal, including a human, consumes sucrose, the sucrose isomerase will act on the sucrose present in the food, and will convert the sucrose to other sugars. This results in lowering of the glycemic index of the food without changing the formulation of the food.Type: ApplicationFiled: August 21, 2019Publication date: July 1, 2021Inventors: Maaike Johanna BRUINS, Petrus Jacobus Theodorus DEKKER, Jeroen Adrianus Johannes NOOIJENS
