Yellow dextrin primarily acts as a binder, energy supplement, and improves the physical properties of fish feed, with the core goal of enhancing feed quality and breeding outcomes.

The specific functions include:

Enhanced Feed Adhesiveness: Bonds fish feed powder into pellets, reducing disintegration upon entering water, thus lowering water pollution and feed wastage.

Provide energy source: As carbohydrates, they can be digested and absorbed by fish, providing fundamental energy for their growth and activity, and assisting in enhancing the overall nutritional utilization of feed.

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