  • Patent number: 6664381
    Abstract: The object of the present invention is a process for producing pure guarseed flour which produces a transparent and highly viscous solution when dissolved in water. Despite extensive purification, the process provides good yields of pure guarseed flour. The process comprises acid treatment of the initial material, washing the acid-treated split with water and/or neutralization with an aqueous alkaline solution, washing with water and dewatering using an aqueous alcohol solution. Transparent, highly viscous solutions of pure guarseed flour obtained by this process are primarily used in the food industry.
