Title:
METHOD FOR PRODUCING HIGH-PURITY RICE PROTEIN POWDER AND RICE SYRUP
Document Type and Number:
WIPO Patent Application WO/2023/174315
Kind Code:
A1
Abstract:
The invention relates to the technical field of the deep processing of rice, in particular to a method for producing a high-purity rice protein powder and a rice syrup. The method comprises: homogenizing a rice slurry, adding amylase thereto, heating the resulting mixture for a reaction to obtain a rice syrup liquid, and subjecting same to centrifugal separation to separately obtain a liquid-phase rice sugar liquid and a first precipitate; subjecting the liquid-phase rice sugar liquid to decoloration, ion exchange and evaporation to obtain a rice syrup, adding the first precipitate into second wastewater, and subjecting same to washing and centrifugal dehydration to obtain a second precipitate; adding pure water into the second precipitate, stirring same until uniform, heating same to 60ºC or more, maintaining the temperature, and dehydrating same to obtain a filter cake and second wastewater; and crushing and drying the filter cake to obtain a rice protein powder with a high purity and without thermal denaturation. The high-purity rice protein powder and rice syrup are produced by using a physical method combined with an enzyme method, the extraction rate is high, the process is simple, the production cost is low, the product quality is good, and the produced wastewater is recycled multiple times, so that the discharge amount of the wastewater is low.
