陳化期間空氣濕度對(duì)山東和貴州C3F煙片質(zhì)量的影響
Effects of Relative Humidity in Aging on C3F Lamina Quality of Shandong and Guizhou
-
摘要: 為了提高烤煙煙葉的陳化質(zhì)量,，研究了不同陳化期間空氣濕度（52%，60%,，68%）對(duì)山東,、貴州C3F煙片物理指標(biāo)、外觀評(píng)價(jià)和化學(xué)成分變化的影響,。結(jié)果表明,，陳化9個(gè)月的山東、貴州C3F煙片的平衡含水率和填充值隨著空氣濕度的增大而升高,。陳化時(shí)空氣濕度大有利于山東C3F煙片淀粉,、色素和多酚的降解,，但是不利于總氮,、煙堿的降解。陳化時(shí)空氣濕度大有利于貴州C3F煙片總糖,、還原糖和多酚的降解,，也有利于煙葉pH的降低,，但不利于煙堿、總氮和色素的降解,。在外觀評(píng)價(jià)方面,，山東C3F煙片在60％空氣濕度下最好，貴州C3F煙片在68％空氣濕度下最好,。Abstract: Aiming to improve the aged quality of flue-cured tobacco, the changes of physical property, appearance and chemical components in different humidity conditions (T1=52%; T2=60%; T3=68% ) were studied with C3F lamina of Shandong and Guizhou Province. The results showed that, after nine months aging, the content of equilibrium moisture and the filling power of C3F lamina increased with the increasing relative humidity. Involving the laminas of Shandong, high relative humidity was favorable for degradation of starch, pigments and polyphenol, yet unfavorable for degradation of total nitrogen and nicotine. For the laminas of Guizhou, high relative humidity was favorable for degradation of total sugar, reducing sugar and polyphenol, and reducing of pH, whereas unfavorable for degradation of nicotine, total nitrogen and pigments. In terms of appearance evaluation, T2 and T3 demonstrated the best results of C3F lamina of Shandong and Guizhou, respectively.
