The innovation utilizes tuna fish skin, the byproduct of tuna industry. Tuna fish skin contains collagen that can be converted into “halal” gelatin. Tuna skin has a higher collagen and softer compared to fish bone and fish scales, so that the processing is faster and simpler. Production of tuna fish skin gelatin meets all of quality standards, in terms of yield, pH, viscosity, as well as other physical and chemical properties.
