Abstract In recent years, the market has great demand for the instant quinoa. However, the high content of protein and fat in quinoa grain inhibited the gelatinization and extension of starch molecules. The instant quinoa prepared by conventional gelatinization method has poor rehydration. In order to solve this problem, the sectioned heating method was used according to the properties of quinoa starch and protein. The purpose of the first heating stage was to gelatinize the starch with sufficient water, and the technological conditions were: the mass ratio of water to quinoa 4:1, the temperature of water bath 70 °C, the time of water bath 60 min. The purpose of the second heating stage was to denature the protein with less water, and the technological condition was that the quinoa was heated by atmospheric steam for 5 min. The instant quinoa prepared by above method had excellent rehydration. Compared to the raw quinoa, the content of protein, fat and reducing sugar in instant quinoa increased slightly, while the content of starch and polyphenols decreased slightly. The mass loss percentage of instant quinoa was 11.5% and the score of sensory evaluation for the sample prepared under the optimum conditions was 87.
