Descaled skins of fresh seabass (L. calcarifer) with a weight of
2.5e3 kg were obtained from the Kingfisher Holdings Co., Ltd.,
Songkhla, Thailand. Skins were kept in a polystyrene box containing
ice using a skin/ice ratio 1:2 (w/w) and transported to the
Department of Food Technology, Prince of Songhkla University, Hat
Yai within 1 h. Upon arrival, the remaining meat was removed
manually. The skins were washed with cold tap water (10 C),
pooled and used as the composite sample. The samples were placed
in polyethylene bags and stored at 20 C until used, but not longer
than 2 months. Prior to gelatin extraction, the frozen skins were
thawed with running tap water (25e26 C) until the core temperature
reached 8e10 C. The skins were then cut into small pieces
(1.0 1.0 cm2) using scissors.
