4 INTRODUCTION WELCOME TO WHAT S ON YOUR PLATE? EXPLORING FOOD SCIENCE! Why does a muffin rise? Why do some recipes have so many ingredients in common? Why do foods change color during cooking? What can be done to keep them looking good? Have you ever wondered how new foods you see at the grocery store are developed? The idea of food science may be new to you, so take a close look at your next meal. There s food science and food technology behind every bite you take, all the way from the farm to the end of your fork. What s on your plate? It s a mixture of chemistry, biology, and physics. Exploring food science is a hands-on experience. Doing activities, you will discover and learn the basic building blocks of food science in a kitchen laboratory. The activities are more than learning to cook; it s learning why and how things happen in all kinds of foods: breads, muffins, eggs, fruit, vegetables, cheese, candy, beverages, and more. This final unit, Be a Food Scientist, looks at a day in the life of a food scientist by inviting guest speakers or utilizing videos, creating a new beverage, and experimenting with sugar crystallization and caramelization. Be sure to check out the other units to learn more about The Secrets of Baking in Unit, The Power of Protein Chemistry in Unit 2, The Inner Mysteries of Fruits and Vegetables in Unit 3. With your Youth Science Journal, you get to conduct experiments, collect and analyze data, practice sensory science (tasting), investigate career opportunities, and amaze your friends and family with what you ve learned about food! To make sure your experiments come out right, follow the directions carefully. Then take some time to think about what happened in the experiment doing so will open the doors of food science for you! Your Youth Science Journal has information in the "Be a Food Scientist" section that will help you understand and remember the concepts behind the experiments this way you can share it with others. You may even find yourself thinking about a career in food science and food technology. There s a special website for you, too.

6 ACTIVITY.: Exploring Food Science Careers A Day in the Life of a Food Scientist (cont.) WHAT WILL WE DO? In this activity, you get to do in-depth career exploration of food science and food technology careers. Did you know there is a shortage of young people choosing careers in science? This includes careers in science, technology, engineering, and applied science careers such as food science and food technology. There is a constant need for new scientists, including food scientists and food technologists. Your group s facilitator will arrange for a discussion with a food science professional, or videos of interviews with food scientists. WHAT DO WE NEED TO KNOW? An amazing array of sciences is involved in producing food. Think about food science and food technology as applying basic science to food sciences such as chemistry, biology, microbiology, biochemistry, engineering, and mathematics. Food science and food technology are the applications of science to food product research and product development, food manufacturing, packaging, food safety and sanitation, food transportation, labeling, advertising, and marketing. Food science careers extend from the farm to our tables. Food Science vs. Food Technology What s the Difference? The Institute of Food Technologists (IFT) defines these terms as follows: Food Science is the discipline in which engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the underlying principles, and the improvement of foods for the consuming public. Food Technology is the application of food science to the selection, preservation, processing, packaging, distribution, and use of safe, nutritious, and wholesome food.

10 ACTIVITY.: Exploring Food Science Careers A Day in the Life of a Food Scientist (cont.) BE A FOOD SCIENTIST Food scientists and food technologists specialize in many areas and do a wide variety of things. While they develop and produce new and innovative food products you see at your grocery store, they also develop food products for people with special needs. For instance, they develop foods for backpackers, athletes, military troops, astronauts, and those with conditions such as diabetes, heart disease, or gluten sensitivity. If your group did not listen to the interviews with several food scientists at the International Food Technologists website, you may wish to do so on your own. See four food scientists who work for a university, Disney, NASA, and in food packaging. These video interviews are linked from Fu-hung Hsieh: Food Science Professor Brian Thane: Food Packaging Professional Disney Consumer Specialists Michele Perchonok: A Food Scientist at NASA Get Started While in High School To be competitive for college admission, it is vital to have the correct preparatory high school coursework. Talk with high school counselors, and if possible, visit a nearby university offering degrees in food science or food technology; talk with faculty members and students about careers and programs. It s never too early to explore a career in food science and food technology. Typical Coursework in College A Bachelor of Science degree in Food Science and Food Technology includes courses in inorganic and organic chemistry, math and calculus, statistics, food chemistry, quantitative analysis, microbiology, nutrition, biochemistry, physics, food law, food microbiology, food processing, sensory analysis, communication, and food engineering.

11 ACTIVITY.: Exploring Food Science Careers A Day in the Life of a Food Scientist (cont.) FOOD SCIENCE AND NUTRITION WHAT S THE LINK? Perhaps you like the idea of food science, and you also like the idea of eating healthy foods. These two likes can make a very interesting career. A nutritionist or registered dietitian may help guide food scientists to make foods lower in calories, fat, sugar or salt, or higher in beneficial nutrients such as phytonutrients, healthy fats, fiber, calcium, or iron. Registered dietitians complete at least a Bachelor s degree and an internship. The coursework includes nutrition, food science, math, chemistry, biology, microbiology, and biochemistry. This credential requires an unpaid internship that can range from six to 2 months. Registered dietitians then take a national exam. LEARN MORE!
