Microwave Assisted Drying of Short-Cut (Ditalini) Macaroni: Cooking Process and Textural Properties
The colour, re-hydration capacity and macaroni cooking quality, related to cooked weight, cooking loss and firmness of drying of short-cut (ditalini) macaroni were evaluated. The textural properties of uncooked and cooked macaroni samples were measured using a TA-XT2i texture analyser. Protein denaturation of dried samples increased significantly with microwave power level. Physical and textural properties of macaroni samples dried with combined hot air/microwave (210 W) were equal to or better than those dried with hot air. Also, hot air/microwave combination drying exhibited superior cooking properties. Firmness of samples increased while cooking loss decreased generally with microwave application after hot air drying, i.e., hot air/microwave combination shortened the drying time and improved many of the physical, textural and cooking properties of macaroni samples.
