Samples come in identical small containers, with no identification other than a number or letter. A variety of colored lights are wired into the cubicles, and can be controlled by a main switch operated by the testing supervisor. Bathing a brown food in red light gives it a rather alien appearance. A white food under a blue light becomes less than taste-tempting. Subjected to foods of strange colors and eerie appearances, the novice tester realizes how important eye appeal and attractive food color are to eating satisfaction. One test commonly given to new food science students consists of three samples of popular brands of cola drinks. Two of the samples are from one brand and the third is from a popular competitor.

The gelatin flavors, however, did not correspond with the colors. It’s hard to detect orange flavor m a red gelatin mix. And strawberry flavoring that comes masked in a lovely shade of purple becomes a real challenge. The taste test panel serves a variety of purposes. University researchers can utilize it in determining acceptance of college researcfiedproducts and, for a fee, commercial compa nies in the food industry can gather information for new food introductions. Recent experiments conducted with the expert tasters include the com parison of kosher to regular food processing, deterioration of milk, meat taste from various com binations of beef crossbreeding, mushroom processing, ice cream for mulations, and the com parison of potato varieties. 117
