Abstract

ABSTRACT In this study, the yield of gelatin extraction from fish waste was optimized using response surface method. The highest yield was obtained with 0.8% citric acid concentration at 72.95°C for 58 minutes. Then, fish gelatin was modified using ultraviolet radiation to overcome fish gelatin defects including unsuitable rheological properties and low thermo-stability. UV irradiation can create crosslinks via alkyl or phenyl groups of the proteins. The modified sample also showed the highest melting point due to the creation of cross-links and improved emulsification and foaming properties of fish gelatin through structural modification and increased surface hydrophobicity of gelatin.

桐鱼胶的提取工艺优化及物理改性研究

摘要本研究采用响应面法对从鱼类废弃物中提取明胶的产率进行了优化。当柠檬酸浓度为0.8%，温度为72.95°C，持续58分钟时，产量最高。然后，利用紫外线对鱼胶进行改性，以克服鱼胶流变性能不合适和热稳定性低的缺陷。紫外线照射可以通过蛋白质的烷基或苯基产生交联。改性样品还显示出最高的熔点，这是由于交联的产生，并通过结构改性和增加明胶的表面疏水性来改善鱼明胶的乳化和发泡性能。

期刊介绍： The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The journal features articles on various aspects of basic and applied science in topics related to: -harvesting and handling practices- processing with traditional and new technologies- refrigeration and freezing- packaging and storage- safety and traceability- byproduct utilization- consumer attitudes toward aquatic food. The Journal also covers basic studies of aquatic products as related to food chemistry, microbiology, and engineering, such as all flora and fauna from aquatic environs, including seaweeds and underutilized species used directly for human consumption or alternative uses. Special features in the journal include guest editorials by specialists in their fields and book reviews covering a wide range of topics.
