Sensory evaluation is a scientific method that objectively and subjectively analyzes consumer products. The food industry uses sensory evaluation to develop or improve food products. Once a product is approved from development to production, it is the job of those in quality assurance and quality control to maintain the integrity of the product. The purpose of this research was to use sensory evaluation to determine if consumers could discern a difference between two beef jerky products made with the same ingredients, but processed differently. The four flavors tested were Original, Teriyaki, Jalapeño, and Sweet and Spicy.

Results of the paired t-test indicated there was no significant (p>.05) difference in preference between the control and test samples for Original, Jalapeño, and Sweet and Spicy jerky. However, testers significantly (p
