| description | Seaweeds are a potential source of minerals, essential amino acids, fatty acids,
proteins, and various bioactive compounds such as antioxidants. The higher water
content of seaweeds reduces the shelf life and this requires the appropriate
drying method. The drying conditions play a major role in the conservation of
nutrient composition in dried seaweeds. In recent years, the seaweed industry
has used many different drying methods with advantages and limitations. Hybrid
hot-water Goodle dryer (HHGD) which is a special dryer mixed with hot-water and
a Korean traditional heating system (Goodlejang) might be a solution to avoid
these limitations. The present study evaluated the effect of drying conditions
in HHGD on nutrient composition and bioactivities of brown seaweeds. Moreover,
freeze-dryer (FD) and HHGD were employed in this study to compare the dried
outputs obtained from four brown seaweed species. The present study aims to
evaluate the effect of the hybrid hot-water Goodle drying method (HHGDM) on the
nutritional composition and antioxidant activity of dried seaweeds. AOAC
standard methods were used to analyze the proximate composition of dried samples
and their 70% ethanol extract. The intracellular and extracellular antioxidant
activities were evaluated using Vero cells and electron spin resonance (ESR)
spectrometer respectively. High performance liquid chromatography, apoptotic
body formation, and in-vivo experiments were used for further
confirmation of the quality of dried output. The proximate composition results
obtained from drying in HHGD and FD did not exhibit any significant difference.
Moreover, the seaweed extracts from the dried seaweeds by HHGD and FD dryings
were also not different and both significantly down-regulated
in-vivo and in-vitro oxidative stress.
Furthermore, the high performance liquid chromatography results revealed that
the two dryers did not make the major peaks different in the chromatograms.
Freeze-drying method (FDM) provides elevated quality for dried output, but there
are limitations such as high cost and low capacity. The results from a novel
HHGD did not provide any significant difference with the results in FD and
expressed a potential to avoid the limitations in FD. Overall, these findings
solidified the applicability of HHGD over FD. |
