Effects of Different Storage Methods on Total Amino Acid Content in Tender Stem of Triarrhena lutarioriparia from Yuanjiang
摘要
Abstract
[Objective] To establish a method for determination of total amino acid content in tender stem of Triarrhena lutarioriparia from Yuanjiang,to study the effects of four storage methods on amino acid content.[Method] Using ninhydrin colorimetry method to determinate total amino acid content in T.lutarioriparia,screen the best working conditions by glutamate as the standard solution,and measure absorbance at its maximum absorption wavelength at 401 nm.[Result] The total content of amino acid in fresh T.lutarioriparia accounted for 22.0％,the amino acid content under each storage method was in 4.9％-21.2％,average recovery was in 99.3％-99.6％,RSD was in 0.06％-0.52％.[Conclusion] By comparing the contents of total amino acids in four ways,reduced pressure storage is the most beneficial way to reduce the amino acid.The method is simple and effective,less pollution and good feasibility.关键词
