Study on combined heat pump drying with freeze‐drying of Antarctic krill and its effects on the lipids
Abstract To better preserve quality of Antarctic krill for wide food application, a drying method by the combining both the heat pump drying (HPD) and freeze‐drying (FD) was investigated. The effect on its dehydration efficiency, and effects on lipid extraction rate and lipid qualities and cost of t...
