【摘要】 对河南几个主要产烟区烟叶在烘烤过程中淀粉降解的研究结果表明 ,不同生态区、不同品种烟叶淀粉都以变黄阶段降解量为最大 ,是鲜烟叶淀粉含量的 5 4%～ 6 7% ,降解速度以 0～ 48h最快 ,NC89品种平均降解速度为每h 0 .31% ,云烟 85平均为每h 0 .34 % .转入定色后直至干筋降解速度缓慢 ,降解量小 .鲜烟叶中淀粉含量以三门峡地区较高 ,烤后含量低 ,降解幅度大 ,综合品质好 .更多还原

【Abstract】 The studies on the degradation of the starch in tobacco leaves from several main tobacco production regions in Henan Province during flue curing process indicated that the starch had the similar degradation laws in different ecological regions and different breeds during flue curing process.The laws were that the degradation quantity of the starch was the greatest in yellowing stage in the whole curing process and took up 54 to 67 percent of the the starch contained in fresh tobacco leaves.The degradation speed was higher in 0～48 hours than in other stages.The NC89 average degradation speed was 0.31% per hour and the Yunyan 85 was 0.34% per hour.The degradation speed had been slowing down from color fixing to drying vein while the degradation quantity was little.Sanmenxia’s samples contained the highest amount of starch in fresh tobacco but degraded the most completely after curing and had the best general quality.更多还原
