探究生牛乳中游离氨基酸的测定方法—分光光度法

Explore the raw milk in the determination of free amino acids-spectrophotometry

本试验是在加热条件下,氨基酸与茚三酮反应生成紫色物质,该物质颜色深浅与氨基酸含量成正比,用分光光度法可计算出样品中氨基酸含量。

This test is in the boiling water bath under the conditions, amino acids react with ninhydrin to form purple material , the substance is proportional to the color depth and amino acid content, spectrophotometry was used to cal- culate the amino acid content of the sample.
