Drying removes moisture from meat products so that microorganisms cannot grow. Dry sausages, freeze-dried meats, and jerky products are all examples of dried meats capable of being stored at room temperature without rapid spoilage. Proper drying is therefore ensured by adjusting air circulation, temperature, and humidity.

Get More6 Food Drying Methods – Pros, Cons and Best Tips. Food drying is one way to preserve foods for later use. Moisture from food is removed to keep it from spoiling. Proper food drying retains most of the flavor of the food. There are many ways to do this. The most common food drying methods are: and microwave drying.
Get MoreThe original piece before drying is represented in Fig. 10.5a. The effect of surface shrinkage is seen in Fig. 10.5b., where the edges and corners gradually pull in giving the cube a more rounded appearance in the early stages of drying. Continued dehydration gradually removes water from deeper and deeper layers and finally from the center.
