| Popis: | Sugar kelp (Saccharina latissima), a marine macroalga, is a rich source of fibers, vitamins, minerals, and antioxidants. However, investigations on the effects of seasonal variation and the drying methods employed on the kelp composition and quality attributes are limited. In this study, the effects of seasonal variation and different drying methods (sun drying, freeze drying) and conditions (temperature, humidity) employed in a heat pump-based drying system on the physicochemical properties, phenolic activity, and antioxidant capacity of S. latissima grown in Maine, USA, were studied. Fresh sugar kelp samples were dried using sun drying, freeze drying, and heat pump-based drying systems at air temperatures of 30, 50, and 70 °C and relative air humidity levels of 25 and 50%. Seasonal variations in kelp harvest (i.e., early May and end of June) have significant effect (p |
