My first real job was working summers in the Food Science Dept., at the UGA Experiment Station in Griffin. 1980ish. My dad was a plant scientist there, so we did our summer jobs there in other departments. My boss/department head was a good old-fashioned southern Jap. Loved that guy. He had me do all kinds of stuff for him. From making wine out of peppermint candy (pretty sure that was a personal project, and I guess I finally got a good batch when he didn't spit it out), to getting published as a co-author when I was 17 in the Journal of Food Science for my work for him. He was doing a study on solar heat and the disinfestation of food products. So, I built a crude solar oven, infested Gainesgurger dog food patties with insects, put heat probes in them in the solar oven, pull samples out at specified temperature thresholds, incubate them to see if the larvae hatched, and determine at what temp heat will disinfest foods. I suppose the basis of the study was to aid lesser developed countries where food was at a premium, reduce loss of food by being able to inexpensively "purify" it for consumption. Not bad for a high schooler at the time.
I also learned during those summers by observing a rather gross scientist eat mayo from a jar kept on top of a cabinet at room temp, that it really doesn't go bad. I never bought into that and still consume my mayo from the fridge.
