The present study was carried out to develop papads (Indian cookie) from potato (Solanum tuberosum L.) and rice (Oryza sativa) blends and to analyze them for organoleptic, physicochemical, phytochemical and shelf life quality. Two processing cultivars (Kufri Chipsona-1, Kufri Chandramukhi) and one commonly grown cultivar (Kufri Pukhraj) were evaluated for processing into papad. Based on preliminary sensory trails, papads with boiled potato mash (60%) and gelatinized rice (30%) level of supplementation were found to be most acceptable and these papads were subjected to nutritional evaluation. Results were compared with rice papads (control). Protein content and yield was significantly (p<0.05) higher in control papads compared to potato supplemented papads. Oil uptake significantly (p<0.05) increased on supplementation with potato. Bioactive compounds including ascorbic acid, total
phenolics and total antioxidant activity measured as DPPH radical scavenging activity increased significantly (p<0.05) on incorporation of potato. Between the cultivars, papads enriched with Kufri Pukhraj, a table variety which is considered unfit for processing, displayed the highest phytochemical content and total antioxidant activity. Sensory evaluation indicated higher overall acceptability scores of potato enriched papads compared to control. During storage of papads at room temperature for up to 3 months, significant (p<0.05) changes in the moisture content, phytochemical content and antioxidant activity were observed. Storage studies showed that the potato supplemented papads can be stored safely for 3 months of storage at ambient temperature.
