Companion animal freeze-dried feed manufacturing method and companion animal freeze-dried feed manufactured according to the method {Freeze-dried Feed for Companion Animal and Method}

The present invention relates to a method for manufacturing freeze-dried feed for companion animals using nano-technology and a protein binder, and more particularly, when raw meat is ground to a nano level, the content of raw meat can be increased by up to 90% by adding a protein binder. It relates to a method for manufacturing freeze-dried feed for companion animals with excellent preservation of flavor and taste and less destruction of nutrients and enzymes.

It is the most widely raised companion animal at home, and in the case of dogs and cats, feed containing raw meat is the most preferred.
