Research Conference, September 1984
    GR&DC Research Programme
    .PROPOSED REVISIONS FOR 1985 1987
    Work Area 05(C) Process Research - Novel Cigarette Technology
    General
    The broad objectives of the programme remain unchanged.
    The total effort in the group will be increased by one graduate and
    two assistants to reinforce the effort available for research into novel
    tobacco and filter materials, e.g. highly-expanded extruded tobacco.
    There will be changes in emphasis in the programme structure in accordance
    with recommendations made by the CAC companies as a result of the circulation
    of the booklet explaining the role of the Novel Cigarette Technology Group,
    and the recent programme review. Greater emphasis will be placed on research
    into products designed to enhance smoker reaction, at the expense of some
    work on low weight/cost opportunities.
    It is anticipated that the current large volume of sponsored work on products
    for the CAC companies and the PAG will continue.
    Programme Revisions
    1. Improved smoker reaction
    The key tasks shown in-the 1983-84 programme were generalised to cover the
    investigation of the performance of a large number of structured products
    and, as such, remain unchanged. Annular, variable density and variable
    composition tobacco rods have the greatest short term interest and will
    receive continuing support in 1984-5.
    In addition to the filter concepts aimed at meeting the MPDC requirements,
    new work Is anticipated on products providing a modified puff-by-puff
    profile.
    2. Low weight/low cost products
    Initially promising work using a food extruder, at the Food Research Insti-
    tute, Norwich, produced highly expanded tobacco materials with low density
    and reasonable smoke character. Lower CO/tar ratio and sidestream smoke
    levels were recorded in prototype products. Significant effort will be
    allocated to this activity'during 1985-86 and it is hoped the work will be
    underpinned by the acquisition of a suitable extrusion facility for GR&DC.
    Contract work previously performed by RAPRA on closed/open cell foams will
    be transferred to Brunel University.

    Otherwise, there are no changes to the programme. Time scales will reflect
    the reduction of effort as a whole for this project and the inclusion of
    the new work on extruded 'tobacco products.
    3. Reduced biological activity
    During 1984, studies were made on the effect of changing cigarette combus-
    tion/pyrolysis temperature profiles by using thermal conductors. Unexpected
    observations of reduc , ad CO/tar ratios, especially in sidestream smoke, have
    encouraged a wider investigation of products employing the principle, as it
    is thought that there may be accompanying changes in specific activity.
    The rate at which specific ideas from the Novel Cigarette Technology Group
    can be evaluated by the Biological Reserarch Group will , continue to depend
    upon the work load in the latter area. Current arrangements permit 5/6
    submissions'per year.-
