Optimization of spray-drying parameter for production of better quality orange fleshed sweet potato ( L.) powder: Selected physiochemical, morphological, and structural properties.

Orange Fleshed Sweet Potato (OFSP) tuber is a rich source of β-carotene with potential antioxidants and phenolic compounds, nevertheless it is highly perishable root crop. Hence, we considered the optimization of parameters for the preparation of OFSP powder in spray drying technique. This study was designed by the Response Surface Methodology (RSM) with three factors in three levels considered in Central Composite Design (CCD).
