Ice cream lab report
This experiment was about finding the fat content and molecules in foods that were chosen from our campus cafe. 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 cafe 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 cafe, 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.
Here are our numbers from the experiment: 136. After the ether was used to wash away the oils and fats, Dr. Some of the labels of the ice cream were misleading as to what was actually in the container. Knight had placed all the foods to be used in the lab into the drying oven. 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. Such as, some that stated it was low fat ice cream was in fact a sherbet or custard. Our group used to mortar and pestle to grind up the portion of the ice cream into a very fine substance. This caused our experiment to not produce the results we expected. 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.
