Abstract
The buzz button is an edible flower that induces a tingling, electric sensation in the mouth and alters the perception of different flavors. The buzz button's taste-altering effect is thought to be caused by the bioactive compound spilanthol. The present article details a laboratory exercise that explores taste perception principles using the buzz button in an undergraduate Sensation and Perception course. A detailed step-by-step guide for the laboratory exercise is included along with analyzed student results. Students first sampled various food items that spanned the different taste sensations (i.e., salty, sweet, sour and bitter) and then rated their perceived taste intensity on a scale from one (not intense) to ten (very intense). Next, students consumed a buzz button and resampled each food item as well as re-rated their perceived taste intensities. It was found that students' perceived taste intensities for sour items and sweet items were decreased after consuming the buzz buttons. Additionally, students also completed a post-activity survey in which they indicated that this was an interesting and enjoyable exercise. This highlights the value of this particular hands-on demonstration in teaching about the connection between taste and tactile perception.
