Extraction and Characterisation of Flavoured Tobacco by GC-MS Studies and Validation of Results by GC-FID to Investigate Hazardous Flavour Ingredients

Flavoured tobacco is mainly consumed in India and neighbouring countries like Pakistan, Afghanistan, and Nepal and the hazards are known. Considering the need to identify such flavouring ingredients and a simple analytical method was required to quantify such favouring ingredients and hazardous / allergens, we selected top brands available in India for investigation. We simply extracted the ingredients by triturating with Diethyl Ether, evaporating solvent ether and reconstituting the extract in Acetone & Ethanol for GC-MS & GC-FID work respectively. The flavour ingredients were identified, and hazardous ingredients, viz. Diethyl Phthalate was identified. It was found around 2.5% to 3.0%. The GC-MS method was validated with GC-FID analysis with Linearity, LOD & LOQ study.
