HPLC analyses were performed to determine vitamin C level in spray dried and initial guava puree.The research shows 170oC is most fine and applicable temperature compare to any other temperature to give minimum vitamin C loss. Vitamin C deterioration depends both on temperature and water activity but experimentally proved water activity would play a more dominant role compared to temperature. Hence, a fast reduction of moisture content at higher temperature will help retaining vitamin C. First order reaction is used to describe the deterioration of vitamin C in spray drying process.
