Unit 3, Lesson 2: The Science of Food

Eating is something we do every day without much thought, but who would ever think that there is so much planning and care that goes into the preparation of the foods we eat and keeping us safe in the process?

Food Science incorporates and applies knowledge from biology, chemistry, nutrition and even engineering to safeguard, process, package, and distribute foods that are nutritious, wholesome, affordable, desirable and safe to eat.
