| 摘 要： | 运用电感耦合等离子体原子发射光谱法(ICP-AES)考察了外源添加植酸酶对大麦发芽过程中游离态K+、Na+、Ca2+、Mg2+、Zn2+含量的变化。实验发现:添加外源植酸酶能提高发芽过程中游离态金属离子的含量,K+、Na+、Ca2+、Mg2+、Zn2+含量同比可提高10.7%、23.4%、16.3%、8.0%、75.5%。通过比较金属离子含量的变化可以为制定合理的制麦工艺提供参考。

| Abstract: | Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES)was adopted for studying the content changes of dissociative metal ion K+,Na+,Ca2+,Mg2+,Zn2+,influenced by exogenous phytase in the process of the barley sprout.The experiment found that adding exogenous phytase could improve the contents of the dissociative metal ion in the germination process and the contents of K+,Na+,Ca2+,Mg2+,Zn2+ could be increased up to 10.7%,23.4%,16.3%,8.0%,75.5%.It provided a reference to formulate a reasonable method of wheat malting by the comparison of the content changes of metal ions. |
