Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

been used as a sweetener and flavoring agent in foods and beverages. The sweetness of honey is due to the different forms of carbohydrate present in honey such as monosaccharides‚ fructose‚ glucose and disaccharides‚ maltose‚ isomaltose‚ maltulose‚ sucrose and turanose (Ayoub Meo et al.‚ 2016). Honey is rich in Vitamin B6‚ Vitamin C‚ trace vitamin B‚ amino acids‚ antioxidants‚ folic acid‚ iron‚ minerals‚ zinc and niacin (David‚ 2007; Fatimah et al.‚ 2013). Honeys contain high osmolarity and low pH which

High Fructose Corn Syrup We owe a great deal to the Native Americans who introduced the Pilgrims to the maize plant. They were the first to realize its great potential as a main stable in our diets. We took that simple little plant and transformed it into the most grown grain in the United States. It has been genetically enhanced to the point that it can now produce two hundred bushels of corn or better per acre (Pollan‚ p.37) making corn the ideal item to be transformed into our sweetener

non-reducing sugar can be hydrolysed using dilute hydrochloric acid. After hydrolysis and neutralization of the acid‚ the product may be a reducing sugar that gives normal reactions with the test solutions (Benedict’s solution /Fehling solution). Sucrose is the most common disaccharide non-reducing sugar. TEST FOR REDUCING SUGAR Procedure 1. A liquid food sample does not need prior preparation except dilution if viscous or concentrated. For a solid sample prepare a test solution by crushing
