Glucose can be divided into monohydrous glucose and anhydrous glucose according to different manufacturing processes. Monohydrate glucose: starch or starch as raw materials, through liquefaction, saccharification of glucose solution, and then through refining, concentrating, cooling crystallization to produce a product containing a clean water. Glucose, also known as corn glucose, maize sugar, or even simply referred to as glucose, is the most widely distributed and most important monosaccharide in nature, and it is a polyhydroxyaldehyde. Pure glucose is colorless crystal, sweet but not as sweet as sucrose, soluble in water, slightly soluble in ethanol, insoluble in ether. Aqueous solution rotates to the right, so it is also called "dextrose".
