Grape-Nuts Grape-Nuts Grape-Nuts is a breakfast cereal developed in 1897 by C. W. Post, a former patient and later competitor of the 19th-century breakfast food innovator, Dr. John Harvey Kellogg. The cereal originally prepared by C. W. Post when developing the product was a batter that came from the oven as a rigid sheet. He then broke the sheet into pieces and ran them through a coffee grinder to produce the "nut"-sized kernels. Despite the name, the cereal contains neither grapes nor nuts; it is made with wheat and barley. Post believed that glucose (which he called "grape sugar") formed in
Sugar gut. DNA and RNA are built up of the monosaccharides deoxyribose and ribose, respectively. Deoxyribose has the formula and ribose the formula . Because sugars burn easily when exposed to flame, the handling of sugars risks dust explosion. The risk of explosion is higher when the sugar has been milled to superfine texture, such as for use in chewing gum. The 2008 Georgia sugar refinery explosion, which killed 14 people and injured 40, and destroyed most of the refinery, was caused by the ignition of sugar dust. In its culinary use, exposing sugar to heat causes caramelization. As the process
