202500 Carolina BioKits: Food Nutrient Analysis
Carolina BioKits® Nutrient Analysis
: Food
In this introduction to food chemistry, students per- form qualitative tests for sugar, starch, lipid, protein, and vitamin C on standards and control samples. Students then use these tests to determine the iden- tity of 2 unknown substances. Instructional material describes the function of these nutrients in the body, their importance, and how the qualitative tests work. Materials are sufficient for a class of 30 working in pairs. Note: Sold only to schools and businesses.
