Introduction The purpose of this lab is to determine the effects acid and sugar in various amounts have on a cornstarch paste. The importance of this experiment is to examine what causes starch to thicken or thin which is relevant to obtaining the desired viscosity for recipes that involve starch cookery without complication. Factors to be considered in the thickening power of cornstarch include the concentration of starch‚ extent of gelatinization thus temperature and duration of heat‚ and the addition of

and no photosynthetic organisms to use. Water also exhibits viscosity. One can observe the effects of viscosity alongside a stream or river with uniform banks. The water along the banks is nearly still‚ while the current in the center may be swift. This resistance between the layers is called viscosity. This property allows smaller fish to live near the shore‚ while larger fish are able to swim efficiently in strong currents. Viscosity is also responsible for the formation of eddies‚ creating turbulence

Aspartame has been proven to be 160 to 220 times sweeter then real sugar This synthetic chemical is commonly known as NutraSweet or Equal. Over half of the U.S. population currently consumes it. Aspartame came onto the market in 1981‚ and has accounted for more then half of all the complaints that the FDA receives each year. Aspartame was accidentally discovered in 1965 by a chemist trying to develop an ulcer drug. The FDA earlier then 1981 did not approve it because it had been tested with

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied

2.1 Synthesis of p-Toulichydrazone and Resacetophenone Schiff base (RAPPTH): p-Toluic hydrazide (1.5018g) and Resacetophenone (2‚4Dihydroxyacetophenone)(1.5215g) were dissolved in methanol and Refluxed in the presence of few drops of acetic acid for 7 hours on water bath with constant stirring. The resultant mixture was transferred in a china dish and allowed to cool naturally. Light brown crystals were obtained. The compound was recrystalized from water. The % of yield was 80%

The Case Of Diane Fleming Diane Fleming ‚ a native of Colorado born in 1957. At the age of 4 she moved to Missouri and was raised on a farm. As a teenager Diane became preganant with her first child by her first husband‚ only to leave that marriage and marry again. While in her second marriage she had another son‚ who soon she later divorced. As a grown adult Diane decided to move to Virginia‚ where she had place an ad in the paper in 1989 looking for companionship

Objectives of the Study This study evaluates the genotoxicity‚ and teratogenicity/antiteratogenicity of the methanol leaf extracts of Tamarindus indica (TE). In particular‚ the study aims to: determine the genotoxicity of TE in terms of: mitotic index chromosomal aberrations micronuclei formation assess the developmental toxicity and teratogenicity potential of TE to zebrafish embryos; and verify the potential of TE to rescue zebrafish embryos from ethanol-induced teratogenicity.

Yogurt is a valuable health food for both infant and elderly people. The nutritional constituents of yogurt are derived from the milk used in making it‚ those that are synthesized by the lactic acid bacteria and those that are added by the manufactures. The nutritional value of the milk protein is well-preserved during the fermentation process. Like most dairy products‚ it is a good source of protein. The milk proteins in yogurt are partially hydrolyzed and therefore become more digestible. In comparison

different approaches to health education For my health education campaign I have chosen to teach my listeners about sweeteners that are replacing sugar‚ such as Aspartame. Aspartame is made up of three chemicals: Aspartic acid‚ phenylalanine‚ and methanol. NutraSweet‚ Equal‚ Spoonful‚ and Equal-Measure‚ all of these are brand names for aspartame‚ the most popular low-calorie sugar substitute used in more than 90 countries to sweeten foods and beverages. According to aspartame information its use
