Gas-Liquid Chromatographic Quantitative Determination of Vanillin and Ethyl Vanillin in Foods
Keyword(s):
Abstract A gas-liquid chromatographic method for vanillin and ethyl vanillin in foods has been devised. Vanillin and ethyl vanillin are extracted into methylene chloride, and the extract is purified, concentrated, and then chromatographed on an EGSS-X column. Recovery of vanillin and ethyl vanillin averaged 99.54 and 98.05%, respectively.
