Correlation between pH and nicotine content in extract of nonsmoking tobacco product - snus
All tobacco products even non-smoking contain nicotine, which has special effect on consumer’s organism and causes addiction. Necessity of nicotine content in tobacco products regulation inspires researches in this field. Popularity of non-smoking product snus is growing. Main advantage of this product is absence of smoke formation and as the result its consumption is possible in any place where smoking is prohibited. Snus contains tobacco, salt (NaCl) for aroma stabilization and preservation, sodium carbonate (Na2CO3) for acidity regulation, propylene glycol for water retaining, flavoring and water. Physiological effect on consumer’s organism has only nicotine which is present in unbound form. Unbound nicotine content can be regulated by changing acidity of the product. For research samples of snus with the same ingredients content but different sodium carbonate content have been prepared. It has been discovered that changing sodium carbonate content leads to altering of unbound nicotine content in extract. Sample of snus with 6 % of sodium carbonate contained 0.51 % of unbound nicotine. Maximum score after tasting had sample with 6 % of sodium carbonate. It has been discovered that maximum content of sodium carbonate in the product should be 6 %. As the result recipes and technological instructions for manufacturing non-smoking tobacco product with altering nicotine content have been developed.
