Arabinose is also known as L(+)-arabinose, L(+)-pentose, pectinose, etc. It is a left-handed monosaccharide separated and extracted from a colloid secreted by a tree called Arabica by complex chemical and physical methods. Arabinose rarely exists in free form in nature. It is usually combined with other monosaccharides and exists in the form of heteropolysaccharides in plant pulp, gum, hemicellulose, pectin acid, bacterial polysaccharides and certain glycosides. As a low-calorie sweetener, arabinose is widely used in the food industry and can be used to make healthy foods such as sugar-free foods and low-sugar foods. In addition, it also has many uses in the fields of medicine and health foods, biological experiments, bioengineering, flavors and fragrances, etc.
