Enzyme Lab Daniyal Abdali (Rachel Lee) (Sarina Dolch) SBI 3UI Mr. Vrabec October 20‚ 2009 Test #1 * Add a small piece of cracker in test tube #1 and add Lugol’s solution. Observation #1 * The cracker turned a black colour when the Lugol’s solution was added to it. This was a positive result‚ meaning that the cracker contains starch. Test #2 * Add a bigger piece of cracker in test tube #2‚ add 5 mL of Benedict’s solution‚ place in a boiling water bath‚ and record observations

Concentration of liquid foods is a fundamental operation in many food processes; it is completely different from dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum

With an improved procedure the question could have been answered with this methodology‚ but the aim was to find out the affect of carbohydrates on blood glucose levels‚ but the methodology provided an answer for the question without going into depth of the biochemistry and carbohydrate structure. This could be solved by amending the aim or by constructing some sort of pre-experiment with the bread that would be used to compare the structure of Danskt Rågbröd

Low Calorie Diet Versus Low Carbohydrate‚ What is the Difference? Comm/155 05/12/13 Sandra Davis Being overweight and obese has become an increasingly alarming problem in this country. In 2007 the Center for Disease Control stated that between 1980 and 2004 obesity prevalence doubled among adults‚ and over 34 percent of all American adults were overweight or obese in 2006. Obesity is known to cause an increased risk of many diseases‚ such as heart disease‚ high blood pressure‚ diabetes‚ and
