The objective of this research was to determine the acceptability and preference of peanut butter and three different flavors of soynut butter among humans. Six hundred and sixty-two volunteers (401 females, 258 males and 3 unknown) between the ages of 18 and up were randomly asked to fill out a demographic survey and taste 1 tsp. (5.33 g) of three different soynut butters (creamy, creamy with honey, and creamy with chocolate) and 1 tsp. (5.33 g) of peanut butter on saltine crackers. After taste testing the soynut butters/peanut butter, volunteers were asked to rate each product on a 9-point hedonic rating scale based on appearance, texture, and flavor; the subjects were also asked as to whether they would purchase the nut butters. Demographic information such as participants' age, gender, year in school, and ethnicity were collected, along with questions concerning their frequency of exercise, eating and smoking habits, and health status of themselves and their families.The creamy with honey and creamy soynut butters were rated highest by both genders for all variables (i.e., appearance, texture, flavor, purchase). The purchase variable determined statistical significance between females and males. The females indicated by their rating that they would be more likely to purchase the chocolate soynut butter vs. the peanut butter, while the males indicated purchasing preference of peanut butter over the chocolate soynut butter.Given that both creamy with honey and creamy soynut butters were accepted by this population based on appearance, texture, and flavor, future research in this area should focus on soy foods in humans and biochemical parameters, marketing niches, specific ethnic or age preferences, and education of the health benefits of soy. / Department of Family and Consumer Sciences
