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.
Claims12
A process for producing a non-derivatized polygalactomannan guarseed flour, having a viscosity of 45 to 10,000 mPa·s as a 1% aqueous solution, a content of proteins and acid non-hydrolyzable substances of 0.8 to 0.9%, and a transparency of at least 70% when measured as a 0.5% aqueous solution at a wavelength of 500 nm, said process consisting essentially of the steps of:
- (a) treating guar splits with an acid;
- (b) washing said acid-treated splits one or more times with water and/or neutralizing said acid-treated splits with a first aqueous alkaline solution;
- (c) treating said splits with a second aqueous alkaline solution;
- (d) washing said splits with water;
- and
- (e) dehydrating said splits with an aqueous alcohol solution.
