2. Different fiber elasticity: Compared with fish glue, bamboo leaf glue has better fiber elasticity and can meet different technological requirements.

3. Different nutritional value: Bamboo leaf gum is superior to fish gum in fiber elasticity and nutritional value, and has better stability and high temperature resistance.

4. Different application fields: bamboo leaf gum is used in textile, paper-making, food, medicine, daily chemical and other industries, while fish gum is mainly used in food industry, such as fish balls, crispy fish skins, fish cakes and so on.
