Abstract:The drying technologies of pineapple peel were investigated by varying the drying temperature and material thickness. The analysis of the drying curve showed that the material thickness had higher effect on the drying efficiency than the other examined factor and a positive relevance was found between the drying temperature and drying rate. It was also found that the nutrition component of the dried pineapple peel was influenced by the drying temperature. The optimum material thickness and drying temperature were determined as 6 kg/m2 and 70 ℃, respectively, under which the product was rich in pineapple aroma, loose-textured and with a uniform color.
