Functional and antioxidant properties of cookies incorporated with foxtail millet and ginger powder.

The functional, sensory, nutritive, phytochemical and antioxidant properties of flours derived from wheat, foxtail millet and ginger along with the cookies formulated from these ingredients was studied. The foxtail millet (20, 30 and 40%) and ginger powder (5, 10 and 15%) blended wheat flours were investigated and compared to control (100% wheat flour). The increase in substitution levels of both the alternatives improved the functional properties of the composite flour and cookies formulated. Sensory analysis revealed that cookies prepared from 30% foxtail millet and 10% ginger powder had comparable scores. These were further subjected to nutritive and phytochemical analyses. The results revealed that cookies formulated using both the alternatives had reasonable proximate composition comparable to control. The substituted cookies had higher total soluble phenolic content and antioxidant capacities in terms of DPPH and ABTS scavenging potential and a strongly positive correlation was observed between the total soluble phenolic content and antioxidant capacities in composite flour and the cookies formulated from the flours. Overall the addition of foxtail millet flour (30%) and ginger powder (10%) improved the nutritional and phenolic linked antioxidant potential which can lead to shelf life extension and enhanced health benefits. © Association of Food Scientists & Technologists (India) 2019.
