hypophthalmus), clown knifefish (Chitala ornata), and tilapia (Oreochromis niloticus) in
Mekong Delta Region, Vietnam for acid‐soluble collagen (ASC) extraction was investigated.
From the SDS‐PAGE profile, ASCs can be identified as type I collagen (consisting of two
different α‐chains and β component in protein pattern). The solubility among individual
collagens was highest at pH 1–2, depending on fish species. FTIR spectra showed a close …
