L-Arabinose CAS 5328-37-0 for Food Grade
Usage:
A common food additive; Arabia sugar; a five carbon aldose obtained by the hydrolysis of gums. Usually present as a binding state in vivo. A component of polysaccharides and glycosides of various gums, hemicelluloses, pectic substances, etc.. There are three kinds of optical isomers, mainly L type, most of which are very small in nature. The relative density of white crystals is 1.585 and the melting point is 155.5 ~ 156.5 DEG C. Soluble in water and glycerin, insoluble in ethanol and ether. Used in medicine and as a medium. In addition to the gum or cherry gum from the gum gland, it can also be produced by the action of calcium gluconate and . Yeast does not ferment.
