What food preservation technique removes moisture?

The food preservation technique that removes moisture is called dehydration. This process involves reducing the water content in food, which inhibits the growth of bacteria, molds, and yeasts that can cause spoilage. Dehydration can be achieved through various methods, including air drying, sun drying, and using dehydrators or ovens. By removing moisture, dehydrated foods can be stored for extended periods without refrigeration.
