TH22904U - Process for extracting gelatin from fish skin - Google Patents

Abstract

The process for extracting gelatin from fish skin is It is created by soaking fish skin in a solution. sodium chloride sodium hydroxide sulfuric acid solution citric acid solution And wash the fish skin as well. The water is clean until it has a pH value of 7. Then soak the fish skins in the water while stirring regularly. With an automatic stirrer that heats to 4560 degrees Celsius, filter the obtained solution to separate water. You will get a gelatin solution. The obtained gelatin solution was evaporated with water and dried until gelatin from fish skin was obtained in order to develop an appropriate method for extracting gelatin from fish skin. Can be used with all types of fish skin, both in water. Fresh and salt water With scales or without scales? Can be scaled or not. until it becomes a gelatin product from leather Fish with high gel strength and the resulting gelatin does not have a fishy smell. which can be used as food additives In dairy products, confectionery, meat products and other foods
