Effects of different harvesting methods on upper leaves air-curing of Cigar

This study aim to investigate the effect of different harvesting methods on the curing effect of cigar tobacco upper leaves, In this study, H382 was adopted as the experimental material, and the effects of the three harvesting methods (stem harvesting, onetime harvesting and piece-by-piece picking.) on moisture content, polyphenol oxidase activity, polyphenol content, amylase activity and internal chemical components of cigar tobacco during air curing were studied. Test data show: 1) The moisture content of one-time harvested tobacco leaves was more suitable for the life activities of tobacco leaves in the air curing process. The water loss of tobacco leaves harvested piece by piece was too fast, but the water loss of leaves obtained by stem harvesting was too slow. 2) In the air curing process, the PPO activity of one-time harvested tobacco leaves was better than others, the PPO activity of tobacco leaves obtained by stem harvesting was higher, and the PPO activity of tobacco leaves harvested piece by piece was lower, which is not conducive to the improvement of tobacco quality. 3) The contents of chlorogenic acid, rutin and anisodamine were higher in tobacco leaves under onetime harvesting treatment after air curing. 4) The chemical components such as nicotine, ratio of two sugars and ratio of potassium to chlorine were more coordinated in tobacco leaves under one-time harvesting. Therefore, compared with stem harvesting and piece-bypiece harvesting, One-time harvesting can effectively improve the beneficial effect of enzymatic browning reaction on cigar tobacco leaves, avoid cigar tobacco blackening and improve its quality.
