BB seaweed powders exhibited significant color differences between powders obtained from BB dried at 35ºC (yellowish-green) and 50–75 °C (brown). High air drying temperature (above 60ºC) significantly reduced the total polyphenolic, carbohydrate content and scavenging activity of aqueous extracts of BB.8Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)DryingDehydrationDewateringEmerging technologiesProducts qualityProcess controlEnvironmentalEvaporationSublimationDiffusionEnergyIntensificationPhaeophyceaeAntioxidant activityCarbohydrateColorPolyphenolsCapítulo de libro10.4995/IDS2018.2018.7496Abierto
