The Center for Tobacco Reference Products in the College of Agriculture, Food and Environment at the University of Kentucky has a long history of providing reference cigarettes and smokeless tobacco products to investigators. We have added to this portfolio five new products of ground raw tobacco from different types of tobacco leaf. These include flue-cured, burley, oriental, dark air-cured and dark fired-cured tobacco. These are in addition to the ground filler tobacco for 1R5F and 1R6F reference cigarettes. The five new products are each from one leaf grade sample of approximately 200 lbs. Each sample was ground to pass a 1 mm screen and conditioned to between 12 and 13% moisture. Samples are stored at -20°C and are available in 50 g units in sealed polypropylene bottles. All samples are stored in air tight buckets at -20°C. These samples are not certified for constituents, but the individual alkaloids, TSNA’s and moisture have been measured on different replications of of each ~7 kg storage container. Measure of each analyte and the corresponding uncertainty values are provided in the poster. Data from one laboratory are available with the product information at CTRP.uky.edu.

The two filler products are the tobacco blends plus expanded tobaccos and reconstituted sheet used in the manufacture of the respective reference cigarettes. 1R5F contain added glycerine and invert sugar, whereas 1R6F contains Isosweet, glycerin and propylene glycol. These two filler tobaccos were also ground to pass 1 mm screen and conditioned to between 12 and 13% moisture and packed in 50 g units in sealed polypropylene bottles and stored at -20°C.
