Validation of an Analytical Method using GC-FID to Determine the Ethanol in Palmyrah Alcoholic Beverages
Abstract
Palmyrah (Borassus Flabellifer. L) Sap is
extracted from female/ male inflorescence of Palmyra palm. The fermented palm
sap referred to as ‘Toddy` which is a mild alcoholic beverage. Fermentation is
done almost immediately by a group of heterogeneous microorganisms. Palmyrah
toddy is distilled to produce the alcoholic liquors like palm wine, arrack. The
aim of this study is to develop and validate gas chromatographic method for the
determination of ethanol content in palmyrah based alcoholic products. Palmyrah
toddy was collected from different Palmyrah societies located in
Chavakachcheri, Karaveddi and Kondavil, Jaffna while Palmyrah arrack was
obtained from Varany distillery respectively. The developed method was
validated for various parameters such as linearity, accuracy, precision, limit
of detection, and limit of quantification. The method linearity was found to be
high with good correlation coefficient values (R2 = 0.999). From the data of
validation criteria it is suggested that the method is suitable for the
determination and for the quality identification of ethanol in Palmyrah based
alcoholic products.
