[目的]尽快推进彩色小麦的产业化进程,满足人们对营养型谷物的需求,实现食品营养天然、食用安全可靠。[方法]采用分层碾磨制粉技术和小麦抗粉碎硬度指数测定方法,研究彩色小麦的营养分布及硬度对各部分营养分离制粉的影响。[结果]彩色小麦的氨基酸总体含量高于普通白小麦13.91%-23.32%,而其主要营养元素Se、Zn、Fe、Ca与普通白小麦比较,‘中普黑麦1号’和‘中普绿麦1号’的Zn、Fe、Ca含量比普通白小麦偏高,而‘中普紫麦1号’则普遍偏低‘,中普绿麦1号’Fe、Ca的含量比较突出,分别高于普通白小麦371.80%和102.86%。彩色小麦的结构营养分布等同于普通小麦,其果皮、种皮、糊粉层和胚芽具有丰富的营养,属营养型小麦,影响营养分离加工的关键因素是小麦的硬度,采用分层碾磨分离技术可基本实现营养分离工业化加工的目的。[结论]该研究为彩色小麦营养资源的开发与合理利用提供了示范。
[Objective] To promote the industrialization of color wheat as soon as possible to meet people’s demand for nutritious cereals and to realize the natural nutrition of food and the safe and reliable food. [Method] The effects of nutrient distribution and hardness of color wheat on the nutritional milling of various parts were studied by the method of layered milling milling and wheat anti-crush hardness index. [Result] The total amino acid content of color wheat was 13.91% -23.32% higher than that of common white wheat, while the main nutrient elements Se, Zn, Fe, Ca were compared with that of common white wheat. ’Zhongpu Rye 1’ and ’Zhongpu The contents of Zn, Fe and Ca in Limei 1 were higher than those in common white wheat, while those in Zhongpu Zimei 1 were generally low. The contents of Fe and Ca in Zhongpu Limei 1 were more prominent, Higher than ordinary white 371.80% and 102.86%. The structure of color wheat nutrition distribution is equivalent to common wheat, the peel, seed coat, aleurone layer and germ is rich in nutrients, is a nutritional wheat, the key factor affecting nutrient separation processing is the hardness of wheat, the use of hierarchical mill separation Technology can basically achieve the purpose of industrial separation of nutrition. [Conclusion] This research provided a demonstration for the development and rational utilization of color wheat nutrition resources.
