The process of air-drying enables a food's inherent vitamins and minerals to be retained over an extended period of time without the need for preservatives.  Since all the natural nutrients are retained, air-dried food doesn't need to be topped up with synthetic vitamins and artificial additives — as is the case with kibble and dry dog foods which lose most of their nutrients during their high-temperature cooking processes. Air-dried food also offers additional benefits to raw feeding in that it eliminates all harmful bacteria and pathogens from food, rendering it shelf-stable for up to 6 months. Put simply, air-dried delivers all the nutritional benefits of raw feeding, but with the ease and convenience of kibble.
