Dehydrated Foods and Frozen Dried Foods and its Difference

Do you wonder what the distinctions are between Dehydrated food products and Frozen Dry Food Products? There are various differences. As a matter of importance, firstly, the procedures used to preserve the food and counteract spoilage and enzymatic breakdown are altogether different things. Other elements you might need to consider are cost, taste, the shelf life, texture, and its nutritional value.

In the case of Dehydrated food items, lack of hydration expels moisture from the food by the flow of hot dry air. The water evaporates and this prevents the development of microorganisms. Oxygen, warmth, light, and dampness(moisture) all added to the breakdown of nutrients and spoilage of food. Because of the use of heat, a portion of the nutritional value will get lost. Utilizing an electric dehydrator will protect a bigger number of nutrients than some alternate methods dehydration. The dehydrated food products are light and for the most part affordable than freeze dry foods products.

But, it has more changes to the surface, fragrance, taste, and nutritional value. It can have a shelf-life till twelve years when stored it appropriately. Re-hydration time is for up to 20 minutes in boiling water and can be up to two hours in cool water.

Frozen dry food removes water from the food by sublimation. The food is fixed in a vacuum chamber which forces the air to move out. The freeze-drying type uses temperatures between - 50 degrees Celsius to - 80 degrees Celsius. This vaporizes the ice and along with these, the frozen dry food products hold more nutrients, and original aroma, flavors and texture. It is light and typically costlier than dehydrated food. This process can take a few days and the expensive equipment.

Freeze dried food has a more extended shelf-life than dehydrated food because up to 98 percent of the moisture is evacuated. The shelf-life can be up to 25 years when appropriately stored. Re-hydration time is 5 minutes in warm water and up to 10 minutes in cool water.

Dehydrated and freeze dried foods are awesome for backpacking as they are light and simple to prepare. They are both fantastic for long-term storage. However, if nutritious value and taste are the best need for you then I would suggest picking frozen food products rather than dehydrated one. I have discovered that it is more affordable over the long period to store food that your family will eat.
