Optimization of Two‐Stage Variable‐Temperature Air‐Impingement Drying of Apple Cubes by CCD ‐ RSM and Quality Evaluation
A two‐stage variable‐temperature air‐impingement drying process for apple cubes was investigated, optimized, and evaluated. Drying stages were identified by monitoring changes in internal sample temperature and moisture content during drying, and the preliminary process conditions were determined according to the h...
