Air-dried

Air-dried describes food gently dried in moving air to remove moisture while limiting heat, yielding a concentrated, shelf-stable product. The lower temperature is presented as preserving more of certain nutrients than high-heat methods, but the term is not uniformly regulated, so the actual time and temperature vary between makers (process claim). Air-drying sits between [freeze-dried](/glossary/freeze-dried) recipes, which remove water by cold sublimation, and conventional kibble made by [extrusion](/glossary/extrusion): it concentrates ingredients into a dense, often chewy texture without the intense pressure-cooking of an extruder. Because water is removed, an air-dried food's energy density per gram is high, so portion sizes look small and feeding guidelines must be followed carefully to avoid [overweight](/glossary/overweight). As with any process label, air-dried describes how a food was made, not the quality of what went in, so the ingredient list and nutritional analysis remain the better guide. One safety nuance: gentler drying does not necessarily match the pathogen-reduction reliability of high-temperature cooking, so raw-material quality and process control still matter. The marker: air-dried is a legitimate, concentrated format whose unregulated wording means the claim alone proves little, a recurring theme for process terms in the [Petipedia glossary](/glossary), alongside [low-temperature cooking](/glossary/low-temperature-cooking) and [cold-pressed](/glossary/cold-pressed).
