| 摘要 | [Objectives] To elucidate the impact of different drying temperatures on the biochemical profile of tobacco (Nicotiana tabacum L.) leaves, the chemical constituents and ultrastructure of Yunyan 87 leaves subjected to different curing temperature settings. [Methods] Near-infrared spectroscopy techniques were utilized to analyze tobacco leaf samples, comparing the changes in chemical constituents at different curing temperatures. [Results] The CK treatment resulted in lower concentrations of nicotine, total nitrogen, chlorine, potassium, and starch, while simultaneously enhancing the levels of total sugar, reducing sugar, and protein. In comparison to the T treatment, the CK treatment appropriately altered the cell structure, reducing the content of cell wall substances. [Conclusions] These findings suggest that low-temperature curing at 44 ℃ during the color-fixing stage is beneficial for improving the quality of tobacco leaves. |
