Freeze drying has been a great food preservation method for years. Watch to learn how history is enhancing your future.

Canning as a way of food preservation was invented in the 1800’s. It has been a popular method for preserving fruits, vegetables, and meats for hundreds of years. However, in the 20th century, a relatively new preservation method called freeze drying appeared on the scene. Freeze drying technology first began to be used by the US Military during WWII to help get medications and food to the troops in Europe before it spoiled. Eventually NASA adopted the technology for their astronaut program, while scientists used theamazing technology for research purposes. Ultimately, commercial companies began preparing and selling freeze dried food.

Although freeze drying is a far superior method of preserving food, the technology has been enormously complicated and expensive for many years. But now, Harvest Right is able to affordably bring freeze drying into every family’s home. This preservation method is far better than canning, better than dehydrating, and even better than freezing itself. This particular paper focuses on the differences between canning and freeze drying.
