Green mussels (Perna viridis) with an
average size of 30-40 individuals/kg were
purchased from a farm in Pattani, Thailand. The
samples were transported in ice with an ice/sample
ratio of 1/2 (w/w) to the Department of Techno-
logy and Industries, Prince of Songkla University,
within 2 h after harvesting. Upon arrival, mussels
were washed with tap water and the flesh meat
was removed from the shells.
