T~C l GOB IT~I I Group Research & Development Centre, British-American Tobacco Co. Ltd., SOUTHAMPTON. 1st October 1976 PROJECT COWPER - EXAMn~ATION OF EXPERIMENTAL BLENDS (Report No. ltD.1417 Restricted) v SUMMARY Exper/mental flue-cured and blended ciKarettes provided by U.T.C. (South Africa) have been evaluated by normal blend and smoke analyses, O/WP analysis and taste and flavour subjective assessment. U.T.C. require Co modify EMBASSY/B. & R. in such a way as to match Rothmans smoke attributes (flue-cured experiment) whilst LUCKY STRIKE modifications should result in Lexinston smoke attributes (blended experiment). The results of the analyses described in this report indicters thac the flue-cured blend and smoke chemistry objectives could be reached by increasing the domestic flue-cured content of the blend at the expense of imported flue-cured and domestic liKht air-cured tobaccos. The PCL which was examined appeared flue-cured in char&ater and did not alter the O/WP pyridines/furfurale balance. Full O/WP analysis suEEested some increase in irritation might result from i~s usa, however. The blended objectives (blend and smoke chemistry) could be reached by increasin8 the content of domestic and/or imported Burley in the blend. Adjustment of the remainder of the blend (less domestic f~ue-cured BAT Co LTD - MINNESOTA TOBACCO LITIGATION r~

-2- and more domestic llghC air-cured) may have assisted in achievlns the objective. In this case, since the added PCL in these samples was flue-cured in type, th£s could not be incorporated without destroying the match. PCL prepared from blended operations mighc, however, be accepuable. Long term panel tests are now in progress in South Africa to evaluate these proposals.
