Collagen Derived from Fish Industry Waste: Progresses and Challenges
Open accessAbstract
Fish collagen garnered significant academic and commercial focus in the last decades featuring prospective applications in a variety of health-related industries, including food, medicine, pharmaceutics, and cosmetics. Due to its distinct advantages over mammalian-based collagen, including the reduced zoonosis transmission risk, the absence of cultural-religious limitations, the cost-effectiveness of manufacturing process, and its superior bioavailability, the use of collagen derived from fish wastes (i.e., skin, scales) quickly expanded. Moreover, by-products are low cost and the need to minimize fish industry waste’s environmental impact paved the way for the use of discards in the development of collagen-based products with remarkable added value. This review summarizes the recent advances in the valorization of fish industry wastes for the extraction of collagen used in several applications. Issues related to processing and characterization of collagen were presented. Moreover, an overview of the most relevant applications in food industry, nutraceutical, cosmetics, tissue engineering, and food packaging of the last three years was introduced. Lastly, the fish-collagen market and the open technological challenges to a reliable recovery and exploitation of this biopolymer were discussed.

Fish collagen shows many advantages over mammalian-based collagen, including reduced zoonosis transmission risk, reduced cultural-religious limitations, cost-effectiveness of manufacturing, and high bioavailability.
“Application of fish collagen reduces zoonosis transmission risk and cultural-religious limitations, but also brings the cost-effectiveness of manufacturing process and high bioavailability.”

Section 3 (Fish Collagen; page unavailable) supports lower disease-transmission risk than mammalian collagen and fewer religious or cultural limitations. Section 5 (Collagen Applications; page unavailable) describes affordability and ease of absorption, but Section 6 (Collagen Market; page unavailable) says marine collagen extraction is cost-intensive and bovine collagen has a cost advantage. The claimed manufacturing cost advantage over mammalian collagen is therefore not supported. (LLM, conf=0.88)
Experimental — accuracy not yet measuredFish wastes (skin, scales) are a cheap and environmentally friendly source of collagen.
“Recently, the attention of researchers has focused primarily on the use of fish wastes (i.e., skin, scales) as a cheap and environmentally friendly source of collagen [107].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
