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

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

Human Body Sugar has occurred naturally in our environment since the dawn of time‚ and mankind has been enjoying its sweet taste almost that long. After all‚ glucose occurs naturally in corn‚ fructose is the natural sweetener found in fruit‚ sucrose occurs naturally in sugar beets and cane‚ and lactose is found in milk. They all taste "equally" sweet on the tongue‚ but our bodies can tell the difference between these monosaccharide ’s‚ and they most certainly don ’t have equally beneficial effects

and let sit for 3 hours. 4.You can carefully scoop the crystals out of your bowl or cup to get a better look at them. Rock Candy: It’s easy to grow your own sugar crystals! Sugar crystals are also known as rock candy since the crystallized sucrose (table sugar) resembles rock crystals and because you can eat your finished product. You can grow beautiful clear sugar crystals with sugar and water or you can add food coloring to get colored crystals. It’s simple‚ safe‚ and fun. Boiling water is

substituted for three hydroxyl groups in the sugar molecule sucrose (white table sugar)‚ creating a tightly bonded‚ highly stable molecule. The tight bonds that hold the molecule together prevent the body from recognizing sucralose as a sugar‚ therefore preventing it from being metabolized and causing most of it to pass through the body undigested. Although sucralose has been used outside

overconsumption of energy and thus may contribute to the global sugar epidemic. This epidemic can lead to a different epidemic such as chronic disease. In addition‚ sugar provides only “empty calories”‚ potentially leading to nutrient inadequacy‚ which can lead to corresponding health consequences. There are many sugar substitutes that can be used and the most recent one that came into the news spotlight is stevia. Of course as with all sugar products and its substitutes there are problems. The controversy
