Abstract:Rice power，wheat power and oat power were used as raw materials to produce extrusion restructuring rice.The main nutritional components of three kinds of materials were analyzed，then，using the formula uniform design method to generate 15 kinds of materials ratio.The retrogradation properties of the samples prepared according to the 15 kinds of materials ratio was carryied out，at the same time，combining the sensory evaluation and intuitive analysis，the best material ratio was determined.The results showed that the best material ratio was as follows：rice power∶wheat power∶oat power＝4.5∶4.5∶1（weight ratio）.According to this ratio the reconstituted rice produced by extrusion processing technology was the most difficult to retrograde，and had good sensory quality and balanced nutrition.The study could provide theoretical reference for the production of new kind of self heating rice with reconstituted rice as the raw material.
