| Abstract: |
| 【Objective】Effects of adding inositol in the germination process on the content of dissociative metal were investigated to provide information for developing a more reasonable malting process.【Method】Using barley“schooner”as the experimental medium,Inductively Coupled Plasma Atomic Emission Spectrometry(ICP AES)was adopted for studying the content changes of dissociative metal ions Ca2+,Mg2+,Zn2+,K+,and Na+ under the influence of inositol additives in the barley sprout process.【Result】We found that adding exogenous inositol could improve the contents of the dissociative metal ions in the germination process.Compared to the control group,the largest content of Ca2+,Mg2+,Zn2+,K+,and Na+ could be increased by 7.5%,4.2%,30.3%,9.8% and 7.9%,respectively.【Conclusion】The inositol can promote the release of metal ions in barley germination process and improve the content of free metal ions. |
