Comparative study of threadfin bream (Nemipterus japonicas) scale collagen extracted using pineapple waste juice and citric acid / Nurul Hasanah Abd Majid.

Collagen was isolated from the scale of threadfin bream using 0.5 M citric acid and pineapple waste juice at the duration 12hrs at 4 °C. The collagen physiochemical characteristics were studied and compared. The collagen yield were about 2.93 to 52.83% (on a dry weight basis), depending on the extra...

Pineapple waste juice treated collagen were light yellow (L = 89.18, a* = -0.19, b* = 9.28) while collagen produced using 0.5 M citric acid were white (L = 96.00, a* = 0.22, b* = 0.99).
