Drying temperature effect on powder physical properties and aqueous extract characteristics of Fucus vesiculosus

The effect of air drying temperature on physical properties of dried Fucus vesiculosus seaweed and the antiradical capacity and composition of its aqueous extracts were studied. Air drying was performed in a tray dryer employing different temperatures (35, 40, 60 and 75 °C). Dried seaweed (12.2 g wa...

Description
Summary:The effect of air drying temperature on physical properties of dried Fucus vesiculosus seaweed and the antiradical capacity and composition of its aqueous extracts were studied. Air drying was performed in a tray dryer employing different temperatures (35, 40, 60 and 75 °C). Dried seaweed (12.2 g water (100 g) −1 dry solid) was milled and particle size characterization and colour analysis of obtained powder were performed. Seaweed powder dried at different temperatures showed significant differences regarding colour properties. Lower brightness and yellowness values were determined in samples dried at 50 and 60 °C in comparison to those dried at 35 °C; greenness at 50 °C was enhanced. Nevertheless, particle size distributions of powders were invariant with drying temperature. Dried seaweed powders (
