The color is an influential parameter for deciding the quality of a product but it gets severely affected by heat treatment. While dehydration, the product is exposed to heat resulting in discoloration of the product. Drying of the liquids and purees can be done using a different kind of equipment viz. convective tray dryer, drum dryer, freeze dryer, and spray dryer. Due to different limitations in these drying methods, researchers have been continuously working to explore new innovative methods of drying that may help in reducing product quality losses due to direct heat application. Refractive window drying is one such technique that gained a lot of attention in recent years, owing to the numerous benefits it claims. The basic aim of this study was to explore the benefits of using refractive window drying for maintaining the color of the dried product.
