OPTIMIZATION OF DRYING PROCESS OF CORN NOODLES USING FLUIDIZED BED DRYER
Drying process was one of the main factors in preserving noodles because it can reduce water content to less than 12 % (w/w (weight by weight)). The objectives of this study were to optimize the drying process of corn noodles using fluidized bed dryer (temperatures of 50 °C, 60 °C, and 70 °C with ai...

| Summary: | Drying process was one of the main factors in preserving noodles because it can reduce water content to less than 12 % (w/w (weight by weight)). The objectives of this study were to optimize the drying process of corn noodles using fluidized bed dryer (temperatures of 50 °C, 60 °C, and 70 °C with airflow velocities of 0.73 m‧s-1, 1.53 m‧s-1, and 2.17 m‧s-1) and to determine the influence of water addition (60 %, 70 %, and 80 % (w/w)) to the dough of corn noodles. The results showed that the best rehydration profile of dried noodles was obtained from drying process at temperature of 60 °C with airflow velocity of 2.17 m‧s-1. The quality of dried corn noodles was influenced by final moisture content of dried noodles and water addition. The critical moisture contents on water additions of 60 %, 70 %, and 80 % were 12, 11, and 10 % (w/w), respectively. The results also showed the optimum quality of dried corn noodles which was obtained from the dough with water addition of 80 %, drying temperature of 60 °C with velocity of 2.17 m‧s-1 for 107 minutes, and moisture content of 10 %. This has similar properties of moisture content, cooking loss, elongation, and hardness to the conventional drying. |
