?新寧縣濃香型烤煙提質(zhì)增香烘烤工藝研究?

　　摘 要：為了實現(xiàn)新寧縣濃香型烤煙提質(zhì)增香的目標(biāo)，以山地栽培的K326和云煙87上部煙葉為材料，進(jìn)行低溫低濕、中溫中濕、高溫高濕3種不同變黃烘烤工藝的比較試驗。結(jié)果表明：中溫中濕變黃烘烤工藝從點火到熄火歷時149 h;單桿煙葉烘烤成本較低，為1.99元/桿;云煙87、K326采用該工藝烘烤后，煙葉均價和上等煙比例最高，分別為24.46、24.08元/kg和60.2%、59.3%;同時，煙葉的外觀質(zhì)量表現(xiàn)符合國家煙葉標(biāo)準(zhǔn)，煙葉主要化學(xué)成分比較協(xié)調(diào)。而采用低溫低濕變黃烘烤工藝烘烤的煙葉出現(xiàn)了少量煙葉掛灰、葉片較薄的不正�，F(xiàn)象;采用高溫高濕變黃烘烤工藝烘烤的煙葉多為檸檬黃色、青筋較多、油分稍有、葉片結(jié)構(gòu)稍密、身份稍厚，葉肉主要化學(xué)成分不協(xié)調(diào)。綜合比較，認(rèn)為中溫中濕變黃烘烤工藝適合新寧縣煙葉產(chǎn)區(qū)山地?zé)熒喜繜熑~烘烤。

　　Abstract： In order to improve the quality and aroma of strong-flavor flue-cured tobacco in Xinning county， based on the upper tobacco leaves of Yunyan 87 and K326 cultivated in mountainous areas， the comparative experiments of three different yellowing and baking processes of low temperature and low humidity， medium temperature and medium humidity， and high temperature and high humidity were carried out. The results showed that： the yellowing and baking process with medium temperature and medium humidity lasted 149 h from ignition to flameout; the baking cost of single-stem tobacco leaves was lower at 1.99 Yuan/stem; the average price of Yunyan 87 and K326 was up to 24.46 and 24.08 Yuan/kg respectively due to their elite cured-leaf proportion reaching the highest by 60.2%  and 59.3% ; at the same time， the appearance quality of tobacco leaves conformed to the national tobacco leaf standard， and the main chemical components were relatively coordinated. However， the baking process with low temperature and low humidity induced a small amount of ash-stained and thin leaves in abnormality. Most leaves with high temperature and high humidity were slightly oily and lemon yellow with more projecting veins， slightly dense leaf structure and slightly thick identity （leaf identity means overall evaluation based on leaf thickness， density  and mass per unit area）， and the main chemical components of the leaf cell were not harmonious. According to the comprehensive comparison， it is believed that the yellowing and baking process with middle temperature and middle humidity is suitable for mountain tobacco in Xinning County.
　　Key words： strong-flavor flue-cured tobacco; baking process; economic benefits; appearance quality; chemical composition; Xinning
