Freezing it Faster Keeps it Fresher. Thanks, Clarence Birdseye!
Episode description
Think about how much space frozen foods take up in a grocery store. How did this all start? On a journey to the arctic, USDA scientist Clarence Birdseye made the observation that fast freezing maintains the quality of food. When he returned to the US, he invented the machinery that resulted in the frozen food industry as we know it today. In this episode we discuss why frozen blueberries are not stuck to one another in a solid block, the importance of fast freezing for ice cream texture, and why just freezing foods cannot make them safe.
