In order to produce the high quality of dried-ear mushroom, various drying methods such as hot-air drying at $40{ sim}80^{ circ}C$ , freeze drying and drying in vinyl house were carried out. Drying hours of hot-air drying, freeze drying and drying in vinyl house were 12.5~21.5, 36.0 and 72.0 hrs, respectively. Vitamin $D_2$ content of sample was the highest as $6.77{ mu}g/g$ DW in drying in vinyl house and then followed by freeze drying as $5.90{ mu}g/g$ DW and hot-air drying as $1.89{ sim}5.01{ mu}g/g$ DW. After dry, external appearance and color of mushrooms applied hot-air drying and drying in vinyl house were better than freeze-dried one. After rehydration, water uptake of sample in drying in vinyl house and hot-air drying at $50{ sim}60^{ circ}C$ were 17.8 and 19.3~21.0 times, respectively. The methods of drying in vinyl house and hot-air drying at $50{ sim}60^{ circ}C$ also led to high hardness, good shape and resilience. As the results of production of dried-ear mushroom with high quality, we suggest that the best method for drying is the drying in vinyl house due to not only high vitamin $D_2$ content, good external appearance and color after drying but also high hardness and good shape after rehydration. |
