In this work, we studied 28 commercial Virginia and US blends described using various thematic variable groups. Our purpose was to explore the possibility of an explanatory linear model connecting structural dimensions of these groups. A group...

Near infrared reflectance spectroscopy has proved to be very useful for predicting concentrations of chemical compounds in tobacco, classification or pattern recognition of cigarette blends. The resulting measurement of a sample is a whole...

The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of...

Today in the tobacco industry, one of the main scientific challenges is to understand the formation of some smoke compounds ("Hoffmann analytes"). For several years, work has been conducted in order to know the influence of cigarette design...

Group classification of tobacco blends is commonly performed using several different types of compositional data including tobacco compounds, additive or process components. But all of these wet chemistry methods are relatively time-consuming. A need...

The influence of the method of harvesting, by stalk (T), or by leaves (F) and the date of harvesting (80, 100, 120 days) on the physical and chemical characteristics of dark air-cured tobacco PB D6 and its smoke have been studied from 1990, 1991 and...

The chlorophyll content of tobacco is determined by a reflectance measurement on powder and is given by a green index . Initially, the determination of the green index was made on powder finely ground at 15% water content and compacted in a pellet....
