Quality assessment of value-added Indian recipe papad prepared from dehydrated carrot pomace powder

Abstract

Fruit and vegetable processing byproducts have a high concentration of biologically useful components and nutritional fibre, though they are frequently discarded as manufacturing waste. The purpose of this study was to improve the nutritional value of the Indian recipe papad, a low-moisture dish with a thin, crisp, wafer-like texture, by utilizing the beneficial properties of dehydrated carrot pomace powder (CPP), which is usually discarded as a food industry bio-waste. Carrot pomace powder was prepared and examined for nutritional and functional properties (10, 20, and 30%), and the developed samples were coded as P0 (control, 100% black gram flour), P1 (black gram flour: carrot pomace powder; 90:10), P2 (black gram flour: carrot pomace powder; 80:20), and P3 (black gram flour: carrot pomace powder; 70:30). The physical, sensory, and storage properties of the developed value-added papads were evaluated. Adding CPP to the flour mix increased the moisture, ash, and crude fiber content while decreasing the protein and carbohydrate content. Based on sensory evaluation, sample P1 was found to be the most acceptable by the sensory panel. The product's microbiological studies showed that, up to a 30-day storage period, the product was well within safe limits. Based on the water activity (at 36.7ºC/ 83% RH) and overall acceptability scores, triple-laminated aluminum bags were considered an appropriate packaging material for storing the value-added papads. This study has established the incorporation of CPP as a healthier alternative to produce an inexpensive, fiber-rich, value-added papads.
