Maximizing Collagen Yield from Underutilized Lumpfish (<i>Cyclopterus lumpus</i>) Skins by Optimizing Pre-Cleaning and Extraction Methods.

ABSTRACT: Female lumpfish (Cyclopterus lumpus) are a primary target of commercial fishery for their roe, a substitute for caviar. The remaining carcasses are underutilized rest raw material. The pre-treatment and acid extraction conditions of collagen from lumpfish skins were optimized. Full factorial design was used to optimize the alkali pre-treatment conditions with NaOH. The optimal conditions were X₁ = 0.1 M (NaOH concentration), X₂ = 6 h (NaOH treatment time), X₃ = 4 °C (treatment temperature) and X₄ = 1:5 (w/v, solid to liquid ratio). Optimized conditions for collagen extraction with acetic acid were investigated using a Box-Behnken design. The result suggested a concentration of 0.9 M acetic acid, treatment temperature of 21 °C
