The Neptone one-step process is the true low temperature process. Typical freeze-dry product brochures claim a low temperature process for “most” of the drying cycle. It is a little known fact that to reduce the moisture content of frozen meats to below 6% (required to prevent microbial growth) the freeze-dry process requires the kibble to be heated at temperatures up to 176º F for up to 6 hours. The Neptone one-step process, on the other hand, utilizes high inlet air temperatures. The hot air is acting on a wet product and the product temperature would rarely exceed 122º f and for very short periods, limited to minutes. Neptone Green Lipped Mussel Powder has a typical moisture analysis of < 5%, ensuring no microbial growth can occur.
