[00:00.00]Narrator: Listen to a conversation between a student and her professor.
[00:06.66]Pro: Before we get started, I...I just wanted to say I’m glad you chose food science for your major course of study.
[00:13.79]Stu: Yeah, it seems like a great industry to get involved with. [00:16.88]I mean with a four-year degree in food science, I'll always be able to find a job.
[00:20.84]Pro: You're absolutely right. [00:22.67]Before entering academia, I worked as a scientist for several food manufacturers and for the US Food and Drug Administration. [00:30.93]I even worked on a commercial fishing boat in Alaska a couple of summers while I was an undergraduate. [00:36.68]We’d bring in the day's catch to a floating processor boat where the fish got cleaned, packaged and frozen right at sea.
[00:45.51]Stu: That's amazing! [00:46.99]As a matter of fact, I'm sort of interested in food packaging.
[00:50.89]Pro: Well, for that, you'll need a strong background in physics, math and chemistry.
[00:56.32]Stu: Those are my best subjects. [00:58.38]For a long time, I was leaning towards getting my degree in engineering.
[01:01.78]Pro: Well, then you shouldn’t have a problem. [01:04.68]Uh, and fortunately, at this university, the department of food science offers a program in food packaging. [01:11.68]Elsewhere, you might have to hammer courses together on your own.
[01:15.55]Stu: I guess I luck out then. [01:18.26]I am… so since my appointment today is to discuss my term paper topic, I wanted to ask, could I write about food packaging? [01:27.72]I realize we're supposed to research foodborne bacteria, but food packaging must play a role in all of that, right?
[01:33.57]Pro: Absolutely! Maybe you should do some preliminary research on that.
[01:37.38]Stu: I have! That's the problem. [01:39.89]I'm overwhelmed.
[01:41.56]Pro: Well, in your reading, did anything interest you in particular? [01:45.12]I mean something you’d like to investigate.
[01:48.41]Stu: Well, I was surprised about the different types of packaging used for milk. [01:53.53]You know, clear plastic bottles, opaque bottles, card board containers..
[01:57.98]Pro: True! In fact, the type of packaging has something to do with the way milk's treated against bacteria.
[02:05.26]Stu: Yeah, and I read a study that showed how light can give milk a funny flavor and decrease its nutritional value. [02:11.61]And yet most milk bottles are clear. [02:13.93]What's up about that?
[02:15.18]Pro: Well consumers like being able to visually examine the color of the milk. [02:19.94]That might be one reason that opaque bottles haven't really caught on. [02:23.99]But that study... I'm sure there is more studies on the subject. [02:28.19]You shouldn't base your paper on only one study.
[02:32.79]Stu: Maybe I should write about those opaque plastic bottles. [02:36.03]Find out if there is any scientific reasons they aren't used more widely? [02:40.37]Maybe opaque bottles 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? [02:50.50]I don't have a...
[02:51.91]Pro: You know, there is a dairy not far from here in Chelsea. [02:55.10]It was one of the first dairies to bottle milk in opaque plastic, but now they're using clear plastic again. [03:01.79]And they're always very supportive of the university and our students, so if you wanted...
[03:07.19]Stu: Yeah, I like that idea.
