摘要:

研究云南不同烟区片烟醇化过程中外观颜色以及内在化学物质变化差异,为云南烟区醇化片烟的使用提供理论依据。取云南3个产区片烟进行醇化,对比分析其在醇化过程中的颜色以及内在化学物质变化差异。不同产区片烟在醇化过程中色差值Lb与总糖、总氮、烟碱呈现逐渐下降趋势,云南文山片烟色差值L、色差值b、总糖、总氮下降幅度大于云南保山与云南大理;还原糖与质体色素降解产物先上升后下降,云南大理峰值出现时间晚于云南保山与云南文山;色度值R、苯丙氨酸降解产物、西柏烷类降解产物、棕色化产物逐渐上升,不同产区变化幅度表现为云南文山>云南保山>云南大理。云南文山片烟在醇化过程中,片烟的外观颜色与内在化学物质变化幅度更大,达到最佳醇化期所需时间少于云南大理与云南保山。

Abstract:

The paper aims to study the appearance and color and intrinsic chemical substances of flue-cured tobacco lamina during the aging in different production areas of Yunnan. The differences of chromatic aberration, chroma, chemical components and aroma components of flue-cured tobacco lamina in three production areas during the aging were analyzed. It is found that the chromatic aberration of L, b and total sugar, total nitrogen and nicotine of flue-cured tobacco lamina decrease gradually during the aging, the decrease of chromatic aberration L, b, total sugar and total nitrogen of Wenshan flue-cured tobacco lamina are greater than those of Baoshan and Dali; the degradation products of reducing sugar and plastid pigment first increase and then decrease, and the peak value of Dali flue-cured tobacco lamina appears later than that of Baoshan and Wenshan; chroma value R, phenylalanine degradation product, cedar degradation products and browning products are increasing gradually, and the variation range of different production areas are: Wenshan> Baoshan> Dali. In conclusion, the appearance and color and the intrinsic chemical substances of Wenshan tobacco lamina change more during the aging, and the time required for the optimal aging period is less than that of Baoshan and Dali.

Key words: flue-cured tobacco lamina, chromatic aberration, chroma, aroma substance, chemical composition
