What Is Alpha Starch for Aquaculture Feed? Alpha starch (pregelatinized starch) is a modified starch that is cold-water soluble and highly digestible. It is widely used in aquaculture feed in Japan as a functional ingredient to improve pellet binding, water stability, and feed efficiency. Due to Japan’s strict requirements for feed quality and environmental […]

WHAT IS PREGELATINIZED STARCH? Pregelatinized is also called Alpha starch. It is a native starch, but cooked, then dried. It has passed the Starch gelatinization process. Starch gelatinization is a process of breaking down the intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water […]
