CORESTA Meeting, Smoke Science/Product Technology, Stratford-upon-Avon, 2005, SSPT 10 Analysis of saccharide in tobacco by High Performance Liquid Chromatography with Evaporative Light Scattering Detection WANG Mingfeng; WANG Haitao; WANG Jian; FAN Duoqing; FENG Lei Kunming Cigarette Factory, Technical Center, Kunming, China. A high performance liquid chromatographic method (HPLC) with evaporative light scattering detection (ELSD) for the determination of saccharide in tobacco was developed. Two of monosaccharide: glucose, fructose and two of disaccharide: sucrose and...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 157, ST06 Studies on the polyphenol oxidase activity during fermentation of tobacco LI S.-J. Test Station, Kunming Cigarette Factory, Kunming, China. Polyphenol oxidase activity was detected by a colorimetric method during the fermentation of flue-cured tobacco. The results show that some activity existed in the leaves of flue-cured tobacco during the process of fermentation. The polyphenol...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 167, ST18 Determination of nicotine evaporation from mainstream smoke using denuder tubes MARINER D.C.; FROST B.E. Rothmans International Services Limited, R&D, Basildon, Essex, England. The rate of nicotine transfer to a smoker and the site of absorption within the human respiratory tract may depend on the distribution of nicotine between the vapour and particulate phases of mainstream smoke. A technique has been developed to...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 167, ST19 Factors related to nicotine physio-chemistry and retention in human smokers SINCLAIR N.M.; FROST B.E.; MARINER D.C. Rothmans International Services Limited, R&D, Basildon, Essex, England. It has been alleged that tobacco companies add ‘ammonia forming compounds’ to cigarette tobacco to "increase as well as control the delivery of the alkaloid nicotine to the respiratory tract of the smoker". It is claimed that such compounds make...
Bull. Spec. CORESTA Congress, Brighton, 1998, p. 191, ST45 Quantifying ETS exposure SEWART A.P. Rothmans International Services Limited, R&D, Basildon, Essex, England. Epidemiological studies into the alleged health effects of ETS typically use questionnaires which, at best, quantify ETS ‘exposure’. However, exposure is not, in itself, sufficient; what is required is a measure of the substance that enters the body...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST03 Benzo(a)pyrene analysis in mainstream cigarette smoke MARINER D.C.; TUCK D.J.; FROST B.E. Rothmans International Services Limited, R&D, Basildon, Essex, England. Benzo(a)pyrene, along with other polycyclic aromatic hydrocarbons, is formed during the incomplete combustion of organic matter and its presence in tobacco smoke is well documented. The low levels present in tobacco smoke and the complexity of the...
CORESTA Meeting, Agronomy/Phytopathology, Montreux,1997, AP66 Genetic modification of tobacco: public perception GREGG E.O. Rothmans International Services Limited, R&D, Basildon, Essex, England. Alteration in the characteristics of plants and crops has traditionally been achieved by breeding techniques; however, recent developments in molecular biology now allow the introduction of specific, desirable traits into plants by direct genetic...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST25 Packaging issues in Europe SINCLAIR N. Rothmans International Services Limited, R&D, Basildon, Essex, England. Traditionally, CORESTA activities have focused on the tobacco plant, processed tobacco plant, processed tobacco and the finished product rather than the packaging in which the product is sold. In Europe, environmental (green) factors, culminating in...
CORESTA Meeting, Smoke/Technology, Hamburg, 1997, ST26 Principles of public health risk assessment SEWART A. Rothmans International Services Limited, R&D, Basildon, Essex, England. Attempts by various regulatory authorities to perform risk assessments on substances such as Environmental Tobacco smoke (ETS) have been controversial and fraught with error. An understanding of Risk Assessment methodology is therefore useful. Public...
