Abstract Peanut butter is a popular ingredient in sandwiches, cookies, and many other common foods. In this cooking and food science fair project, you will roast peanuts in the oven at 350 degrees for 20, 30, and 40 minutes to produce variable levels of color and flavor. Roasting not only adds complex flavors to the peanuts, but it also destroys enzymes that produce off-flavors. Each lot of roasted peanuts will be used to make a batch of peanut butter. You will evaluate each batch of peanut butter for flavor, texture, and color. You can also compare your homemade peanut butter with commercially produced peanut butters. The experimental procedure for this project was developed and field-tested by the Institute of Food Technologists (IFT). A detailed Student Activity Sheet describing the experimental procedure is available on the IFT website. See the bibliography for the link to the IFT. Bibliography Institute of Food Technologists.

Career Focus

If you like this project, you might enjoy exploring related careers.

	Chemist Everything in the environment, whether naturally occurring or of human design, is composed of chemicals. Chemists search for and use new knowledge about chemicals to develop new processes or products.			Food Science Technician Good taste, texture, quality, and safety are all very important in the food industry. Food science technicians test and catalog the physical and chemical properties of food to help ensure these aspects.
	Chemical Technician The role that the chemical technician plays is the backbone of every chemical, semiconductor, and pharmaceutical manufacturing operation. Chemical technicians conduct experiments, record data, and help to implement new processes and procedures in the laboratory. If you enjoy hands-on work, then you might be interested in the career of a chemical technician.			Food Scientist or Technologist There is a fraction of the world's population that doesn't have enough to eat or doesn't have access to food that is nutritionally rich. Food scientists or technologists work to find new sources of food that have the right nutrition levels and that are safe for human consumption. In fact, our nation's food supply depends on food scientists and technologists that test and develop foods that meet and exceed government food safety standards. If you are interested in combining biology, chemistry, and the knowledge that you are helping people, then a career as a food scientist or technologist could be a great choice for you!
