Synthesis method
1. Glucose is one of the most abundant compounds in nature and is a product of photosynthesis. It exists in free form in plant juices, especially in fruits, honey, plasma, and lymph. The glucose content in normal human blood is 0.08%-0.1%, and a larger amount of it exists in the form of combined sucrose, starch, glycogen, cellulose and glycosides. Initially glucose was separated and crystallized from grape juice, hence its name. Industrially produced glucose is produced by hydrolysis of starch. In the past, dilute hydrochloric acid was used to hydrolyze starch. Now, dilute hydrochloric acid is almost completely replaced by enzymatic hydrolysis.
2.Starch can be hydrolyzed to obtain glucose.
Purpose
1. Can be used as nutritional sweeteners, water retaining agents, texture improvers, molding and processing aids.
2. Can be used as reducing agent, biological culture medium and biochemical reagents.
