vacuum drying
Quick Summary
Vacuum drying is a method of food preservation that removes moisture from food products by operating under reduced pressure. This process inhibits the growth of microorganisms and enzymatic activity, thereby extending the shelf life of the food.12
Key aspects of vacuum drying include:
* Mechanism: Operating under a vacuum allows water to evaporate at lower temperatures, which is beneficial for heat-sensitive foods.12
* Applications: It is used for various food products, including fruits, vegetables, and dairy products.12
* Advantages: Reduced bulk of the dehydrated product, making it easier to transport and store.2
* Related Techniques: Freeze-drying is a related method that uses high vacuum to sublimate ice directly into vapor without it passing through a liquid state.12

Drying under vacuum is especially beneficial to fruits and vegetables. Freeze-drying benefits heat-sensitive products by dehydrating in the frozen state without intermediate thaw. Freeze-drying of meat yields a product of excellent stability, which on rehydration closely resembles fresh meat.
