Consumer acceptability of gluten-free cookies containing raw cooked and germinated pinto bean flours

Abstract

Beany and grassy flavors in raw edible bean flours reduce consumer acceptability of bean-based baked products. In order to improve consumer acceptability, beans may be further processed by cooking and germination. However, these operations drive up the cost of end-products. Therefore, it is necessary to develop formulations, using raw edible bean flours that have acceptable sensory attributes. In this study, cooked, germinated, and germinated/steam-blanched (GSB) pinto bean flours were used to make gluten-free cookies, and their sensory characteristics evaluated to determine how their consumer acceptability scores compared. Taste panelists (31) graded cookies made from raw pinto beans with an overall value of 6 on a 9-point hedonic scale (p
