Changes of Some Physical and Chemical Indexes of Redried Yunnan Flue-cured Strips, B2F and C3F,during Ageing

The changes of equilibrium moisture content, smouldering rate, routine chemical composition and pH value of redried Yunnan flue-cured strips, B2F and C3F, during aging were tested. The results showed that the equilibrium moisture content, total sugar, nicotine, total nitrogen, protein and pH value of the strips were obviously decreased with the proceeding of aging, while its smouldering rate was increased to a certain extent.
