There are several reasons why microwave drying of mealworms may be considered a priority:

1. Rapid heating: Microwave heating can heat mealworms quickly and evenly. Compared with traditional drying methods, the drying process can be completed faster, thus saving time and energy.

2. Retain nutrients: Compared with other heating methods, microwave heating can better retain the nutrients in food. Mealworms are rich in nutrients such as protein, fat and trace elements, and microwave drying can better preserve these nutrients.

3. Reduce oxidation losses: The rapidity and uniformity of microwave heating can reduce the oxidation losses of mealworms during the heating process, helping to maintain their quality and taste.

4. Environmental protection and energy saving: Compared with traditional drying methods, microwave drying can usually save energy and reduce the impact on the environment.

5. Strong controllability: Microwave heating has strong controllability and can be accurately adjusted according to the characteristics of the mealworm and the required drying effect, thereby obtaining better drying results.

Taken together, microwave drying of mealworms has certain advantages in terms of efficiency, nutrition maintenance, quality control, etc., so it is considered to be one of the preferred drying methods.
