Effects of Drying Temperature and Humidity Regulation Patterns on Physiology,Biochemistry and Quality of Cigar Tobacco Leaves
摘要
Abstract
To determine the optimal temperature and humidity regulation model for the curing of cigar tobacco in Changsha tobacco-growing area and provide a theoretical basis for optimizing the cigar tobacco curing process,a study was conducted in 2023 in Lianhua Village,Ningxiang City,Hunan Province.Using the middle leaves of the cigar variety Habanas as materials,three temperature and humidity regulation models were set up:La(precise control of temperature and humidity),Lb(precise humidity with broad temperature control),and Lc(broad control of both temperature and humidity).A comparative analysis was performed on the water loss,color changes,key chemical components,and related enzyme activities of tobacco leaves during the curing process under different treatments.Additionally,a comprehensive evaluation system for tobacco leaf appearance quality,physical characteristics,chemical components,and sensory quality was established using the fuzzy comprehensive evaluation method to assess the quality of tobacco leaves under different regulation models.The results showed that the La model effectively regulated the water loss rate of tobacco leaves,promoted the yellowing and browning processes,avoided the occurrence of leaf death and greening,and facilitated the coordinated transformation of carbohydrates,total nitrogen,and nicotine.In the early stage of curing,the La and Lb models were conducive to the full transformation of sugars,while in the later stage,the amylase activity of tobacco leaves treated with the Lc model was relatively low.However,under the Lc model,the polyphenol oxidase activity peaked at 1 019.43 U/(g·min)on the 5th day of curing,indicating that the tobacco leaves entered the browning stage too early,which was not conducive to early-stage material accumulation.Moreover,the enzyme activity declined rapidly,hindering the transformation of polyphenols in the later stage.From the perspective of the comprehensive effectiveness index,the La model had the highest score(79.33),and its tobacco leaf quality met the production standards for cigar wrappers.In summary,the La model is currently the optimal temperature and humidity regulation scheme for cigar tobacco curing in the Changsha tobacco-growing area.关键词
