Xylose is a simple sugar, also known as a monosaccharide, that is found in small amounts in many plant-based foods such as fruits, vegetables, and grains. It is classified as a pentose sugar because it contains five carbon atoms in its chemical structure.
In protein powders and other food products, xylose may be used as a natural sweetener or a flavor enhancer. It has a slightly sweet taste that is similar to glucose, but it is not as sweet as other common sugars like sucrose or fructose.
Xylose is also sometimes used in the production of xylitol, which is a popular sugar substitute that is commonly used in many low-calorie and sugar-free products. Xylitol is derived from xylose through a process of hydrogenation.
Xylose is generally considered safe for human consumption, although it is not commonly used as a standalone ingredient in protein powders. It is more often used as a precursor to other sweeteners and food additives.
