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

The specific functions include:

Enhanced feed adhesion: Bonds fish feed powder into granules, reducing feed dispersion in water and minimizing water pollution and feed waste.

Provide energy source: As carbohydrates, they are digestible and absorbable by fish, providing fundamental energy for their growth and activities, 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 consume; its gelatinized structure also promotes the digestion and absorption of other nutrients by the fish's intestines.
