Abstract:
With the electric-type automatic temperature and humidity-controlled flue-curing barn, The optimized bulk curing process of flue-cured tobacco honghuadajinyuan was studied. The results showed that "leaf yellowing + leaf wilting + vein yellowing + leaf cured dried and fragrant": in the medium humidity model of optimization buck curing had a better economic character and a better appearance quality; the reducing sugar content was higher, the total nitrogen and the protein content were low, the total nitrogen content and the ratio of the reducing sugar contents to total sugar and the ratio of kalium to chlorine were within the appropriate range; The neutral aroma constituents of Aromatic amino acid metabolites and Siebel alkane degradation products larger contribution to the aroma quality were higher than other treatment; As a result tobacco quality in general was improved, with good aroma quantity, full aroma quality, small odor, suitable irritation, comfortable lingering smell, total smoke quality value were best and the fragrance was good (mainly was delicate fragrance).
