Abstract

The aim of this study was to characterize spreadable products based on the utilization of capia pepperseed flour. Chocolate type including liquid chocolate, and molasses type including grape molasses were evaluated. The volatile aromatics compositions, sensory descriptions, consumer preferences and storage stabilities were studied. 24 volatile compounds in chocolate type and 17 volatile compounds in molasses type were quantified. 1,2,3-propanetriol, ethyl acetate and acetic acid in chocolate type, and acetic acid and methyl acetate in molasses type were dominant in concentrations. Volatiles with aroma descriptions of fruity, ethereal, nutty, buttery, cocoa, almond, green, fatty, caramel, vegetable and similar were quantified. The panel sensorially defined both products with 17 definition terms. Significant differences for brownness, nutty, raw vegetable, bitterness, chocolate/caramel, consistency, spreadability, and refreshment were determined, and thought to be caused from the main ingredients used. Consumer hedonic scores were generally higher for chocolate type, but both need improvements. Oil separation and water activity have not changed during the storage, while some color differences and microstructural changes occurred. Furthermore, free fatty acidity and peroxide value was not increased significantly and lower than 1.8% and 2.5 meqO(2)/kg, respectively. Overall, these new pastes could found some market value.
