Allulose is a low-calorie monosaccharide sugar that has the taste and texture of sucrose but with 90% less calories. It is approximately 70% as sweet as sucrose and is also known as D-psicose. Allulose is recognized as GRAS by the US FDA and can be found naturally in wheat, figs, raisins and jackfruit. Allulose is not metabolized by the body and therefore does not increase blood glucose or insulin levels. Allulose is highly soluble and similar to sucrose as its solubility increases with temperature.
