Physicochemical And Rheological Properties Of Fish Gelatin Modified By Tannic Acid

Fish gelatin was gaining attention as an alternative gelatin because mammalian gelatin faced social cultural issue and also health concern. However, fish gelatin has poor physicochemical and rheological properties. Therefore, the purpose of this study was to investigate the physicochemical and rheol...
