SORBITOL 70% Sorbitol is a sugar alcohol with a sweet taste that is slowly metabolized by the human body. This compound can be obtained by reducing glucose, which converts the aldehyde group to hydroxyl. Sorbitol is usually made from corn syrup, but this material can also be found in nature, such as apples, pears, peaches and prunes. [2] Sorbitol is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is a mannitol isomer which is another type of sugar alcohol; the difference between the two is the orientation of the hydroxyl group in carbon 2. [3] Although similar, these two ingredients do not come from the same object in nature. The melting point and its use are also different.
