Ultraviolet-B Radiation Induced Cross-linking Improves Physical Properties of Cold- and Warm-Water Fish Gelatin Gels and Films

:  Cold‐ and warm‐water fish gelatin granules were exposed to ultraviolet‐B radiation for doses up to 29.7 J/cm2. Solutions and films were prepared from the granules. Gel electrophoresis and refractive index were used to examine changes in molecular weight of the samples. Also, the gel strength and...
