Sažetak
Fish processing industry plays an important role in global economy. Due to a growing scope of production and the resulting generation of increasingly larger quantities of waste (fish heads, fins, entrails, skin, bones, meat unfit for consumption and the process effluent), the treatment and recycling of waste is a global trend in line with global tendencies of environmental protection, conservation of water resources and converting of waste into useful products. This waste is partially used for producing less valuable products, such as fishmeal, oil, fertilizer and silage. However, in order to achieve the full potential of the waste and to produce high-value bioactive compounds, such as proteins, amino acids, peptides, enzymes, collagen, gelatin, polyunsaturated fatty acids (PUFA), vitamins, minerals and other high-value compounds, various chemical, biological and innovative extraction methods are applied, some of which still at scientific research stages. By evaluating waste based on the creation of new products, it is possible to achieve a more environmentally friendly use of marine resources and a greater economic benefit for the fish processing sector. Therefore, the main goal of this work is to point out the value of solid and liquid waste generated in fish processing, provide an overview of the composition and properties of bioactive compounds isolated from waste, present procedures and research related to their isolation, as well as their application in different industries.
