简介
Amylose content is commonly used to predict the texture of cooked rice. However, rice classification using only amylose content can misclassify actual sensory quality. Quality assessment of cooked rice can be determined by a combined evaluation of physical, chemical and sensory properties, but this process is costly and requires use of trained panelists. In this study, an alternate method for predicting rice amylose content was investigated. Paste viscosity and cooked rice texture of nine rice varieties were measured that had either low, medium, or high amylose content. Data were analyzed using analysis of variance, Pearson correlation, and discriminant analysis. Results showed that protein content, which played a major role in cooked rice texture, did not correlate with amylose content. Discriminant analysis results showed that only pasting attributes could discriminate the amylose groups but not texture. Pasting …
