French fries, hash browns, mashed potatoes with gravy, potato latkes, there are so many things to make with the humble potato. The potato is a tuber from the perennial plant Solanum Tuberosum of the Solanaceae family. There are actually about 5,000 varieties of potatoes, but most of them can be traced back to the original potato from southern Peru. This single ancestor originated more than 10,000 years ago. In addition to being high in vitamins and minerals, potatoes have a varying amount of starch. Starch is the source of stored energy that a plant uses to feed itself. In this cooking and food science fair project, investigate the starch content of different varieties of potatoes. An easy way to determine the starch amount in a potato is to cut the potato into two pieces, rub them together, pull them apart, and then put the two pieces back together again. Is there a difference in how the different potatoes stick together? Do you notice foam, and if so, do different varieties make different foam? Is there a difference in the stickiness of the foam? Once you have determined starch content, look into how starch content affects boiling the potatoes. Are all of the potatoes fluffy after boiling, or are they waxy? What is the texture of the different potatoes after boiling?

Food Scientist or TechnologistThere 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! Read more
BiochemistGrowing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms. Read more
Food Science TechnicianGood 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. Read more
