Abstract:

To boost the industrialization of color wheat, meet the demand of people on nutritious grain, realize the security and natural nutrition of food. Method to layering peeling milling technology and measurement on wheat anti-crush hardness index are implied to study the influence of color wheat nutriments distribution and it’s hardness to separation milling of each nutritious part. The results showed that total content on amino acid in color wheat was 13.91%-23.32% higher than common wheat. Compared the main nutriments Se, Zn, Fe, Ca between color wheat and common wheat, Se, Fe, and Ca content in ‘Zhongpu Black I’ and ‘Zhongpu Green I’ were higher than common wheat, while the content on ‘Zhongpu Purple I’ was lower that common wheat. Especially the Fe and Ca content in ‘Zhongpu Green I’ were 371.80% and 102.86% higher than common wheat, respectively. This research demonstrated that color wheat was full of nutriments. The purpose for industrial processing on color wheat could be reached by layering peeling milling technology. Meanwhile, it was found that key point affecting on the nutriments separating was the hardness. This study sets an example for development and optimal use of color wheat nutriments.
