Description

technical field

[0001] The present invention relates to a method for the selective oxidation of carbohydrates in the presence of a gold catalyst comprising nanodispersed gold particles on a metal oxide support; to a method for the selective oxidation of oligosaccharides in the presence of a gold catalyst Methods, the gold catalyst comprising nano-dispersed gold particles on a carbon or metal oxide support; and aldonic acid oxidation products prepared by these methods. Background technique

[0002] In the global cheese production process and whey production industry, approximately 1,200,000 metric tons of lactose waste are generated annually. However, lactose, as the basic carbohydrate component of milk, has little economic importance. One reason for this is the discovery that certain populations are lactose intolerant. People with lactose intolerance cannot utilize lactose, and absorbing lactose will produce lactose intolerance reactions, such as diarrhea. A relatively sm...
