Polyphenols are antioxidants that confer potential health benefits. Peanut butters enhanced with high phenolic peanut skins were compared to commercial products deemed acceptable based on sales data. Objectives were: (1) to determine quality characteristics of commercially available peanut butters, (2) to compare quality characteristics of commercial products to peanut butter prototypes containing high phenolics peanut skins, and (3) to assess consumer responsiveness to health claims. Objective tests assessed texture and appearance. Appearance of reformulated peanut butters was comparable to commercial products. Reformulated peanut butters exhibited increases in firmness, adhesiveness, and gumminess and decreased ease of spreadability when compared to commercial products (p<0.05). Focus groups revealed interest in high fiber peanut butters with traditional characteristics. Marketing and packaging as high fiber products should be investigated.
