Dehydration

The ancient method, modern application

NRG Pet Products started the voyage of pet nutrition making a balanced ALL LIFE STAGES diet that was frozen. Besides the logistics of transporting and storing frozen food, the storing of frozen food for long periods of time results in nutrient destruction.

Dehydration is shown to be the gentlest form of food preservation and has overtime proven to be an excellent method of stabilizing the complex nutrients in whole food.

Dehydrating is the oldest form of food preservation. When the water is removed from a food the enzymes present cannot effectively contact or react with the food. The dehydration temperature is maintained so that heat sensitive nutrients are not inactivated or destroyed. Dehydration suspends the activity of enzymes in the ingredients until the food is re hydrated. A unique example of the beneficial effects of dehydration are a species of fish in Africa that survive severe droughts. They lay their eggs in pools of water that dry up during periods that can last for several yeas. The eggs are dehydrated by the sun, when the rains come and the pools fill, the re hydrated eggs hatch and life begins again.

The nutritional losses during dehydration are 3 to 5% compared to 60 to 80% loss during canning and 40 to 60% when frozen. (United States Department of Agriculture Research Division , Composition of Food handbook No. 8). In NRG diets , all nutrients remain in the ingredients, eliminating the necessity of adding a premix containing amino acids, antioxidants (natural and synthetic), vitamin, minerals, enzymes, flavors, or other supplements such and glucosamine and condroitin sulphate.
