Summary of fish collagen productivity by different extraction method and characterization of isolation of collagen from various species of fish.
| Fish species | Source collagen | Extraction method | Characterization | Productivity | References |
|---|---|---|---|---|---|
| Clown featherback (Chitala ornata) | Skins | Acid soluble collagen (ASC) assisted with ultrasonication treatment | Triple-helical structure—type I collagen | Ultrasonication treatment increases collagen extraction yield (27.18-57.35%) compared to standard process (23.46%) | [45] |
| Snakeheads (Channa striata) | Skin, scales | Acid soluble collagen (ASC) | Type I | The recovery yield of fish skin (13.6%) was significantly greater than the recovery yield of a mixture of fish skin and scale (12.09%) | [23] |
| Prionace glauca, Scyliorhinus canicula, Xiphias gladius, and Thunnus albacares | Skin | Pepsin soluble collagen (PSC) | Type I | Collagen yield was obtained from the skin of two species of teleost, and chondrichthyes were 14.16% and 61.17%, respectively | [52] |
| Tilapia (Oreochromis niloticus) | Scales | Acetic acid and ultrafine bubbles | Type I | Scales were used to extract collagen, which resulted in a yield of 1.58% | [27] |
| Lutjanus sp. | Bone | Hydroextraction method | Triple-helical structure—type I collagen | In this experiment, the collagen yield was 4.535%, with a protein concentration of 8,815 mg/mL | [39] |
| Silver carp (Hypophthalmichthys molitrix) | Scales | Acid soluble collagen (ASC); pepsin soluble collagen (PSC) | Triple-helical structure—type I collagen | The collagen extraction yields of ASC and PSC were 5.09% and 12.06%, respectively | [8] |
| Seabass (Lates calcarifer) | Scales | Acid soluble collagen (ASC); pepsin soluble collagen (PSC) | Triple-helical structure—type I collagen | Yields of collagen from ASC and PSC were 0.38 and 1.06%, respectively | [6] |
| Nile tilapia (Oreochromis niloticus) | Skin | Acid soluble collagen (ASC); pepsin soluble collagen (PSC) | Type I collagen with triple-helical structure | Fermentation-ASC (FASC) and fermentation-PSC (FPSC) yields were 4.76 and 8.14 wt%, respectively; chemical-ASC (CASC) and chemical-PSC (CPSC) yields were 4.27 and 7.60 wt%, respectively | [3] |
| Amur sturgeon (Acipenser schrenckii) | Cartilage, fin and scale | Salt-soluble collagen, (SSC); acid soluble collagen (ASC); pepsin soluble collagen (PSC) | Type I collagen SSC and ASC; PSC predominantly type II with triple helical structure. | Yields of collagen from SSC (2.18%), ASC (27.04%), and PSC (55.92%), respectively | [53] |
| Silver catfish (Pangasius sp.) | Skin | Acid soluble collagen (ASC) and pepsin soluble collagen (PSC) | Isolated collagens exhibited amide A, II, and III as a fingerprint for collagen structure | Yields of collagen from ASC and PSC were 4.27% and 2.27%, respectively. ASC and PSC had protein concentrations of 2.27 and 2.70 mg/mL, respectively | [13] |
| Sole fish (Aseraggodes umbratilis) | Skin | Acid soluble collagen (ASC) | Type I collagen with triple-helical structure | The maximum yield of collagen was 19.27 mg per gram of skin and achieved at optimum conditions | [14] |
| Small-spotted catshark (Scyliorhinus canicula) | Skins | Acid soluble collagen (ASC) | Type I collagen with triple-helical structure | The maximum collagen yield was 61.24% | [40] |
| Tilapia (Oreochromis mossambicus) | Bone | Desalinated with EDTA-ASC; EDTA-PSC; desalinated HCl-PSC | Type I collagen which corresponding with secondary structure | Yield of collagen desalinated with EDTA − ASC = 2.5%; desalinated with EDTA − PSC = 7.3%; desalinated by HCl − PSC = 0.5% | [37] |
