Partially defatted tomato seed flour as a fat replacer: effect on physicochemical and sensory characteristics of millet-based cookies
Abstract
Abstract Fat is an essential component for cookies structure and sensory attributes, but there is a necessity to replace or mimic fat in order to prevent lifestyle diseases. Hence, this study investigated the effect of industrial by-product, i.e., Partially defatted tomato seed flour (PDTSF) as a fat replacer on physicochemical and sensory characteristics of millet-based cookies at 10, 20, 30, and 40% (w/w) fat replacement levels. The physicochemical and functional properties of PDTSF were analyzed. PDTSF exhibited excellent nutritional profile and functional properties. PDTSF supplemented cookies showed a significant increase ( p\u2009≤ \u20090.05) in hardness, protein, ash, and carbohydrate content and the significant decrease in spread ratio, fat, and energy value with an increment of PDTSF. Descriptive sensory evaluation of millet-based cookies at all fat replacement levels showed good acceptability. Storage analysis for 30\xa0days revealed as acceptance of cookies is not affected due to moisture intake and hardness. Hence, the results confirmed the positive effect on PDTSF as a whole food fat replacer to produce Reduced- fat millet cookies at 10 and 20% fat replacement levels. Graphical abstract
