Fish Skin Waste: Increased Value Added And The Application (a Review)

Science and Technology

Processing of fishery resources, especially fish, has not been optimally carried out until the utilization of fishery waste, such as heads, bones, scales, and skins. Along with the development of the fishing industry, the waste generated from the company's production also increases. Fish processing businesses almost always produce waste in the form of solids (bones, scales, skin, head) and liquids which directly or indirectly will have an adverse impact on the environment because it causes pollution. This waste is of very low value but if used optimally it will provide significant added value. Fish skin waste can be used to produce several products that have added value. Some of the products resulting from the utilization of fish skin waste from the processing of fishery products are fish oil, skin crackers, leather tanning, collagen and gelatin. Fish skin crackers are one of the diversification of fishery products. The results of fish skin tanning can be applied as raw materials in the manufacture of bags, wallets, belts, jackets, and souvenirs. Gelatin applications can be made as a gelling agent, emulsifier, clarifier and coating in food products.
