When you test food for quality, for example, what kinds of tests are you doing? What are you looking for? Things like that.

Marsha WalkerGUEST
So we offer a service to food manufacturers where we can actually put their food product in a testing chamber.

Marsha WalkerGUEST
So we can control the conditions that it's stored in more professionally than a consumer would.

Marsha WalkerGUEST
And the things that we look for really are easily measured by chemical indicators.

Well, now, when you explain the Food Innovation Center to someone who's never heard of it, what do you say its mission and purpose is? And what are you trying to build there?

Marsha WalkerGUEST
I think the interesting thing is that I was at OSU doing my PhD when the center was being built.

Marsha WalkerGUEST
So I actually kind of have this 27-year perspective But right now, how I really explain it to people is we sit kind of as a bridge.

Marsha WalkerGUEST
And our mission is really about helping transform ideas, whether they come from our entrepreneurs, the startups, researchers on campus, industry partners, into products and solutions that actually work in the marketplace in our world today.
