In order to develop dried carrot pomace of high quality, experiments were conducted in completely randomized design (CRD). The carrot pomace was subjected to various blanching pretreatments i.e. water blanching (WB), steam blanching (SB), citric acid blanching (CB) and potassium metabisulphate (KMS) dipping after blanching (WBS). A control sample (untreated, UT) was kept for comparison. The samples were further dried by various drying methods i.e. convective drying (55°C and 65°C), sun drying

Among the blanching pretreatments, the CB pretreatment showed better efficacy in retaining the quality attributes. Overall, the CB pretreatment followed by convective drying at 65°C was found to be the best drying combination for retaining the quality attributes of carrot pomace. Citation: Alam, M. S., K.
