Abstract:
A large amount of fish processing by-products such as fish skins, fish scales, fish bones, fins and swim bladders are generated along with the development of fish processing industry, and high value utilization of these kinds of by-products has attracted the attention of scientists. Currently, these fish processing by-products are usually made into snack foods, fish meals or collagen products, and due to the higher added-value of collagen products, the extraction of collagen has become a research hotspot. Based on the above background, this work firstly introduced the distribution of collagen in different fish processing by-products, and reviewed the latest developments on the main extraction methods. Furthermore, the extraction rate, purity and physicochemical properties of collagen from different fish processing by-products were also compared and analyzed in this work. Finally, it looked into the prospects and development trends of collagen production using fish by-products as raw materials, proposed that acid swelling-pepsin digestion method was more suitable for fish collagen extraction and had promising prospects especially for fish skin collagen extraction.

摘要： 鱼类加工产业发展的同时，不可避免地产生大量鱼皮、鱼鳞、鱼骨、鱼鳍、鱼鳔等不同鱼类加工副产物，如何对这些副产物进行高值加工利用引起广泛关注。目前，鱼类加工副产物的利用途径主要包括制作休闲食品、饲料鱼粉、胶原等。其中，因胶原产品的附加值空间大，以鱼类加工副产物为原料提取胶原成为当前研究的热点之一。在介绍不同鱼类加工副产物组成特点的基础上，阐述了近年来国内外以不同鱼类加工副产物为原料提取胶原的研究现状，总结分析了从不同鱼类加工副产物中提取胶原的提取率、产物纯度及性质，展望了以鱼类加工副产物为原料提取胶原的发展前景和方向，并提出了酸-酶结合法更适用于鱼胶原的提取，且从鱼皮中提取胶原的前景广阔。
