Abstract
The present study aimed at improving phytonutritional profile of traditional snack (bhujia) by incorporating variety bell pepper. The bell peppers were dried at 50°C which resulted in 4.94%–8.16% increase in total phenols whereas, retained approximately 92.49% total carotenoids and 91.36% of the antioxidant activity in terms of DPPH radical scavenging activity. Gram flour at 5.0% (w/w) level of bell pepper powders was optimized for developing bhujia which significantly (p ≤ 0.05) increased bulk density, minerals, phytonutritional profile, and sensory attributes of bhujia. Total phenols of developed bhujia increased by approximately 11% and antioxidant activity was found 3.5 times as compared to control. Fourier-transform infrared spectroscopy showed the presence of various phytochemicals compounds in the prepared products compared to control. Storage studies (at 25–30°C/50%–87% RH) revealed that the physicochemical parameters remained unaffected except moisture which increased significantly. However, peroxide value and free fatty acids remained well within maximum permissible limits.
