摘要 [目的]研究煙葉分切過(guò)程的質(zhì)量控制指標(biāo)，為煙葉分切的質(zhì)量控制提供參考。[方法]以河南南陽(yáng)方城C3F煙葉為代表，以感官評(píng)吸質(zhì)量鑒定為主要評(píng)價(jià)手段，輔助常規(guī)化學(xué)成分分析，研究了切距允差、切距合格率、切角允差、切角合格率4項(xiàng)關(guān)鍵質(zhì)量指標(biāo)對(duì)切后煙葉質(zhì)量的影響。[結(jié)果]試驗(yàn)表明，切距允差為1 cm，切距合格率要求達(dá)到90%；切角允差為20°，切角合格率要求達(dá)到85%時(shí)，煙葉分切質(zhì)量較為穩(wěn)定，可作為煙葉分切關(guān)鍵指標(biāo)的控制標(biāo)準(zhǔn)。[結(jié)論] 研究可為煙葉分切技術(shù)的推廣應(yīng)用提供必要的技術(shù)支撐。

　　Abstract [Objective] In order to control the quality of tobacco leaf cutting， the key indexes were studied during the cutting.[Method]The permissible deviation and qualified rate of both the cutting distance and the cutting angle were studied on C3F grade tobacco leaf of Fangcheng County Nanyang， Henan Province. Sensory taste was the main mean to evaluate the tobacco quality.The influences of
　　Permissible deviation of the cutting distance，Qualified rate of the cutting distance，permissible deviation of the cutting angle on the quality of cut tobacco leaf were observed by smoking evaluation together with conventional chemical analysis.[Result] Results show that while the permissible deviation of the cutting distance was within 1 cm， the qualified rate of the cutting distance was above 90%， the permissible deviation of the cutting angle was within 20°， the qualified rate of the cutting angle was above 85%， the quality of leaf cutting was stable. Therefore， the four indexes can be used as the key indexes of tobacco leaf cutting in quality control.[Conclusion] The research can provide necessary technical support for the popularization and application of tobacco cutting technology.

　　煙葉分切后再加工、使用，不僅可以提高煙葉使用價(jià)值，增強(qiáng)卷煙企業(yè)原料保障能力，還能加快打葉復(fù)烤企業(yè)的技術(shù)進(jìn)步，提高片煙產(chǎn)品質(zhì)量。針對(duì)單片煙葉質(zhì)量變化規(guī)律、煙葉分切方法確定、煙葉分切設(shè)備開(kāi)發(fā)，國(guó)內(nèi)多家機(jī)構(gòu)都進(jìn)行了深入研究。單片烤煙不同區(qū)位煙片的常規(guī)化學(xué)成分、致香成分、評(píng)吸質(zhì)量存在較大差異，其變化具有一定的規(guī)律性，葉中部分煙葉品質(zhì)相對(duì)較好，葉尖部次之，而葉基部分相對(duì)較差[1-5]。不同煙葉內(nèi)在質(zhì)量與外觀質(zhì)量一致即“內(nèi)外一致”的原則對(duì)單片煙葉不同區(qū)位同樣適用。煙葉外觀質(zhì)量明顯變化的地方內(nèi)在質(zhì)量變化也較為明顯，故煙葉最佳分切位置可通過(guò)外觀質(zhì)量確定[6-7]。然而，對(duì)于影響煙葉分切質(zhì)量的其他控制指標(biāo)尚缺乏系統(tǒng)研究，影響了煙葉分切技術(shù)的推廣應(yīng)用。分切試驗(yàn)和生產(chǎn)實(shí)際驗(yàn)證結(jié)果表明，切距、切角一致的煙片，外觀質(zhì)量、常規(guī)化學(xué)成分、評(píng)吸質(zhì)量一致，能全面反映分切產(chǎn)品的質(zhì)量狀況。因此切距允差、切角均可作為分切質(zhì)量控制的關(guān)鍵指標(biāo)。
