This research compared four different ways to dry Cordyceps militaris mushrooms to determine which method best preserves their delicious taste and aroma. The study found that microwave combined with hot air drying created the strongest umami or savory taste, while vacuum freeze drying best preserved the mushroom’s natural aroma and flavor compounds. These findings help food manufacturers choose the best drying method to maintain the quality and desirable characteristics of Cordyceps militaris products for consumers.
