| Abstract: | The alkaline extraction of rice protein was studied by an orthogonal test.The results show that the extraction rate of rice protein is mostly influenced by ratio of solid-liquid,followed by conditions of NaOH,extraction time and extraction temperature.The optimum process parameters are ratio of solid-liquid 1：10,quality score of NaOH 0.35%,extraction time 6 h and extraction temperature 40 ℃.Under these conditions,the extraction yield is up to 88.87%. |
