Effects of Loading Density of Bulk Curing Barn on Quality of Upper Leaves in Flue-cured Tobacco
摘要
Abstract
In order to study the effects of different loading densities on quality of cured upper leaves to provide evidence for 'optimizing curing technology, experiment with three loading densities treatments, low density (3 000 kg/barn), middle density (4 000 kg/barn) and high density (5 000 kg/barn), was carried out to compare the effects of different loading densities on appearance quality, routine chemical components, neutral volatile aroma compounds and economic traits of the upper leaves. Results showed that: (1) comprehensive score of appearance quality of upper leaves in middle density treatment was highest, suggesting better leaf quality. (2) With the increasing of loading density, contents of reducing sugar and starch remarkably decreased, contents of nicotine and water-soluble total sugar decreased at some extent, while contents of Cl and petroleum ether extracts showed unconspicuous changes. However, the increase of loading density significantly increased the K content. Most quality indexes in middle density treatment were proper and its chemical components were harmonious. (3) Increasing of loading density contributed to the increasing of content of neutral volatile aroma compounds and improvement of aroma quality. Middle density treatment showed the biggest improvement, and its neutral volatile aroma compounds content increased by 14. 64% compared with low density treatment. Conclusively, the quality and economic benefit of upper leaves could be improved under the middle loading density.关键词
