Yellow dextrin primarily serves as a binder, energy supplement, and improves the physical properties of fish feed, with the core objective of enhancing feed quality and farming efficiency.

Its specific functions include:

Enhanced Feed Adhesiveness: Bonds fish feed powder into granules, reducing dispersion in water after feeding and minimizing water pollution and feed wastage.

- Energy Source Provided: As carbohydrates, they are digestible and absorbable by fish, providing fundamental energy for growth and activity, and assisting in enhancing the overall nutritional utilization of feed.

- Enhance palatability and digestibility: Adjusts the hardness and taste of feed, making it easier for fish to eat; its gelatinized structure also promotes the digestion and absorption of other nutrients by the fish's intestines.
