Most commercial pet foods are cooked at some stage in the manufacturing process. This destroys many of the nutrients naturally in the food, especially vitamins.
Happypet’s venison treats are preserved without cooking. The tendon chews are air dried, while the other venison treats are freeze dried.
To freeze dry meat, the product is frozen and the surrounding pressure is reduced in a vacuum chamber.
A small amount of heat is then applied and because the pressure in the vacuum chamber is so low, the frozen water turns straight from ice to gas (water vapor). Shrinkage is minimized, and near-perfect preservation results.
The process of freeze drying food was first used by the ancient Peruvian Incas of the Andes. The Incas stored their food crops at high altitudes in the mountains. The cold temperatures froze the food and the water inside slowly vaporized under the low air pressure.
