No. 37 - Determination of Reducing Substances in Tobacco by Continuous Flow Analysis

(CRM developed into ISO 15153:2003)

Aug. 2010 - second edition

Two procedures for the determination of reducing sugars in tobacco were adopted as CORESTA Recommended Methods N° 37 and N° 38. Studies have shown that the two methods may not produce identical results. For some tobaccos the results obtained with Method N° 37 are higher than those of Method N° 38 because Method N° 37 is sensitive to interferences from reducing substances, other than sugars, present in tobacco. This is reflected in the titles of the two methods. CORESTA has decided to publish both methods since Method N° 37 is easier to implement, while Method N° 38 is more specific.
