Pre-gelatinized Maize Starch

Product Description:

Jianjie® alpha starch is a modified version of maize starch. It excels in solution thickening, water solubility, suspendability, gelatin solution stability, film forming ability, water retention and binding effect. It quickly dissolves in cold water and dispenses with the complexity of heating-based gelatinization. It extensively used in metallurgy, coal briquette, construction material, metal casting, animal feed, oil production and fertilizer.
