Ice cream lab report essays

Ice cream lab report essays This experiment was about finding the fat content and molecules in foods that were chosen from our campus caf. The experiment concentrated mainly on macronutrients, which are the major sources for energy and include carbohydrates, lipids, and proteins. Lipids are needed for the formation of cell membranes, and proteins are needed as enzymes, receptors, and membrane transporters. Molecules may be either polar and stable in water or non-polar and avoid water. Also, in this experiment, micronutrients were involved and are used in the body for overall health and include vitamins and minerals. The procedures for this experiment were as follows: 1. Before entering the lab, students were asked to bring a food source into the lab from the caf to use for the experiment. Some foods were pre-prepared by Dr. Knight such as our food source, ice cream. Dr. Knight had already collected the food from the caf, weighed the food before any extractions or drying, and then put the food into a drying oven to prepare it for our lab. Our group then chose ice cream to conduct our experiment. 2. Our group then scraped out 8.00g of the dried ice cream to use to extract fat and oils into a mortar and pestle. Our group used to mortar and pestle to grind up the portion of the ice cream into a very fine substance. The sample of ice cream was then placed into a coffee filter and funnel and ether was used to wash what oils and fats we could away. This washing was done 3 times to ensure that all the oils and fats were removed. 3. After the washing was complete, the glass rod and mortar and pestle had some of the ice cream still left on it. To ensure that our calculations would be as accurate as possible, we then weighed the mortar and pestle and glass rod before cleaning and also weighed them after cleaning and used the difference to add to our sample. An empty coffee filter ...
