TPO 9 Conversation 1
Listen to a conversation between a student and her professor.
P: Before we get started, I...I just wanted to say I’m glad you chose foodscience for your major courses study.
S: Yeah, it seems like a great industry to get involved with. I mean with thefour-year degree in food science, I'll always be able to find a job.
P: You're absolutely right. Before entering academia, I worked as a scientist forseveral food manufacturers and for the US Food and Drug Administration. Ieven worked on a commercial fishing boat in Alaska a couple of summers while I was an undergraduate. We bring in the day's catch to a floating processor boat where the fish got cleaned, packaged and frozen right at sea.
S: That's amazing! As a matter of fact, I'm sort of interested in food packaging.
P: Well, for that, you'll need a strong background in physics, math andchemistry.
S: Those are my best subjects. For a long time, I was leading towards gettingmy degree in engineering.
P: Well, then you should have a problem. And fortunately, at this university, thedepartment of food science offers a program in food packaging. Elsewhere,you might have to hammer courses together on your own.
S: I guess I like it a lot then. I am… so since my appointment today is todiscuss my term paper topic, I wanted to ask, could I write about foodpackaging? I realize we're supposed to research food-born bacteria, but food packaging must play a role in all of that, right?
P: Absolutely! Maybe you should do some preliminary research on that.
S: I have! That's the problem. I'm overwhelmed.
P: Well, in your reading, did anything interest you in particular? I meansomething you’d like to investigate.
S: well, I was surprised about the different types of packaging used for milk.
You know, clear plastic bottles, opaque bottles, carton board containers...
P: True! In fact, the type of packaging has something to do with the way milk'streated against bacteria.
S: Yeah, and I read a study that showed how light can give milk a funny flavorand decrease the nutritional value. And yet most milk bottles are unclear.What's up about that?
P: Well consumers like being able to visually examine the color of the milk.That might be one reason that opaque bottles haven't really called on. But thatstudy... I'm sure there is more study on the subject. You shouldn't base your paper on only one study.
S: Maybe I should write about those opaque plastic bottles. Find out if thereare any scientific reasons they aren't used more widely? Maybe opaquebottles aren't as good at keeping bacteria from growing in milk after the bottle has been opened for something… but where to begin researching this? I don't have a...
P: You know, there is a dairy not far from here in Chelsea. It was one of thefirst diaries to bottle milk in opaque plastic, but now they're using clear plasticbegan. And they're always very supportive of the university and our students, and if you want it...
S: Yeah, I like that idea.
