Analysis of amino acid composition and content in Asparagus from different sources
Objective To explore the types and contents of amino acids in Asparagus from different sources.Methods Post-column ninhydrin-derived photometry was established to determine the species and contents of amino acids in Guangxi,Neijiang and southwest winter,and performed data analysis using stoichiometry.Results The average amino acid content in Neijiang was 3.06%,3.53%in Guangxi,and 5.73%in southwest China.The amino acid composition and content in Neijiang and Guangxi were similar,and the content was uniform among different batches,the amino acid content in southwest and southwest was quite different from the first two sources,and the different batches were quite different.Conclusion This research provides scientific reference for quality evaluation of Asparagus and the study of its authenticity.
