Physicochemical properties: white crystal or crystalline powder, sweet taste, sweetness equivalent to 0.7 of sucrose. The melting point is 147 ~ 152 ° C, and the relative density is 1.525; Optically active; It is easily soluble in water and has a solubility of 117g at 20 ° C. under the same temperature, the viscosity of its saturated solution is smaller than that of xylitol and glucose. It can reduce warm Fehling's solution. Soluble in water, pyridine and hot ethanol, slightly soluble in cold ethanol. Xylose belongs to five carbon sugar, which widely exists in hemicellulose of natural plants in the state of polycondensation, that is, it is contained in plants in the form of macromolecular xylan, such as sawdust, straw, corncob, etc

Purpose: biochemical research. Biological culture, tanning, dyeing.
