SHOW 302: Smarter Food Processing Techniques


Taking the mush out of canned and frozen vegetables is the assignment for Cornell University food scientists Malcolm Bourne and Cy Lee. Join them in the lab as they look for ways to let green beans retain their snap and help frozen corn taste like fresh-picked. Using less heat to can beans and a shorter cooking time to process corn, the scientists produce vegetables that will satisfy hungry consumers.
