Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula C. 12H. 22O. 11 . For human consumption, sucrose is extracted and refined from either sugarcane or sugar beet.
Glucose is a sugar with the molecular formula C 6 H 12 O 6. Glucose is overall the most abundant monosaccharide, [ 4] a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight.
It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. [13] [14] In nature, grape-sugar breaks up by the action of fermentation into alcohol or carbonic acid, without anything being ...
The three "R"s stand for carbon substituents or hydrogen atoms. [ 1] In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl ( −OH) functional group bound to carbon. [ 2][ 3] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group ...
Sorbitol ( / ˈsɔː ( r) bɪtɒl / ), less commonly known as glucitol ( / ˈɡluːsɪtɒl / ), is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the converted aldehyde group (−CHO) to a primary alcohol group (−CH 2 OH). Most sorbitol is made from potato ...
Retrieved June 30, 2014 – via Google Books. Commercially, invert sugar is prepared as a syrup of about 70% soluble solids concentration. Invert sugar can be produced by holding a 65% sucrose solution containing 0.25% hydrochloric acid at 50°C (122°F) for one hour. Sodium bicarbonate should then be added to neutralize the acid.
In the United States, HFCS is among the sweeteners that have mostly replaced sucrose (table sugar) in the food industry. [7] [8] Factors contributing to the increased use of HFCS in food manufacturing include production quotas of domestic sugar, import tariffs on foreign sugar, and subsidies of U.S. corn, raising the price of sucrose and reducing that of HFCS, creating a manufacturing-cost ...
Sugar alcohols can be, and often are, produced from renewable resources.Particular feedstocks are starch, cellulose and hemicellulose; the main conversion technologies use H 2 as the reagent: hydrogenolysis, i.e. the cleavage of C−O single bonds, converting polymers to smaller molecules, and hydrogenation of C=O double bonds, converting sugars to sugar alcohols.
