Due to its brittle texture, strong nutty flavors, dark color profiles, has seen limited use food products for human consumption. The objective this study was develop palatable chip product maximized level inclusion BSG. Chips were contained levels ranging from 8% 40%, physical sensory properties chips evaluated. Spent samples provided Iron Monk Stillwater dried at low temperature milled flour formulation. evaluated water activity, color, texture (fracture force). An informal evaluation conducted evaluate flavor, probability purchase using 5-point hedonic rating scale. Results showed there no significant differences containing different measurements between L ∗ id="M2"> values BSG, but some b id="M3"> values. consumers preferred with 40% they also more likely chips.
