| abstract | 1362751 Treating tobacco IMPERIAL CHEMICAL INDUSTRIES Ltd 5 Feb 1973 [2 March 1972] 9808/72 Heading A2C The flavour of tobacco when smoked is enhanced by catalysed thermal degradation of the tobacco at a temperature of 100C to 300C until the weight of degraded material is less than 90% of the weight of the original tobacco. Preferred catalysts are strong acids or their salts with weak bases, ammonium sulphamate being particularly preferred. Alkaline catalysts may also be used, but in this case the degraded tobacco should be freed from the catalysts before smoking. In the examples, various kinds of tobacco were degraded using either ammonium sulphamate or sulphuric acid as catalysts and the degraded tobacco was ground and slurried with sodium carboxymethyl cellulose, glycerol, citric acid, potassium citrate and calcium carbonate and the slurry was cast to form a sheet.n[GB1362751A] |
