Polysaccharide mixtures used as stabilizers having identical sugar units, but differing in their linkages can be identified with confidence by means of methylation analysis. Such mixtures are methylated with sodium hydride and methyl iodide in anhydrous dimethylsulfoxide. The methylated products are acid hydrolyzed and the resulting methyl sugars are separated and identified by thinlayer- or gaschromatography.
用作稳定剂的多糖混合物，其糖单元相同，但连接方式不同，可以通过甲基化分析可靠地鉴定出来。此类混合物在无水二甲亚砜中用氢化钠和碘甲烷进行甲基化。甲基化产物进行酸水解，所得甲基糖通过薄层色谱法或气相色谱法进行分离和鉴定。
