Abstract:
Different types of rice varieties as materials, the embryo residual rate as parameters, rice varieties suitable for embryo-remaining rice processing were screened in this paper. Meanwhile, nutrients of embryo-remaining rice, such as ash, proteins, amino acids, amylose, micronutrient elements, etc. were determined. Finally, the quality difference of embryo-remaining rice from different varieties was investigated to further clarify the adaptively of embryo-remaining rice processing of different varieties. The results showed that the significant difference of the embryo residual rate was found after processing of different types rice varieties and the embryo residual rate processing by japonica rice varieties was significantly higher than that by indica and hybrid rice varieties and the average embryo residual rate were 76.1%, 66.83% and 64.96%, respectively.Quality determination demonstrated that the quality of embryo-remaining rice from varieties with high embryo residual rate was better than that from varieties with low embryo residual rate. So embryo-remaining rice could be processed by any rice varieties and its quality was decided by the varieties type and seeds shape.Therefore, the development of rice varieties used embryo residual rate as parameters was feasible to improve high yield and quality of embryo-remaining rice.
