重加里料结合高温烘焙对山东低次烟叶理化特性及感官品质的影响
Effect of heavy casing addition and high-temperature baking on physicochemical properties and sensory quality of low-grade tobacco leaves in Shandong
摘要
Abstract
[Objective]To mitigate the quality defects of low-grade tobacco leaves from Shandong,such as heavy off-notes and strong irritation,this study employed heavy casing addition and high-temperature baking technologies,and explored the effects of different processing techniques on their quality.[Methods]Taking low-grade tobacco leaves from Shandong as the test material,we selected eight leaf samples treated with different processing treatments to analyze the effects of various processing conditions on the physical properties,chemical properties,sensory quality,and aroma-forming substances of the leaves.[Results]In terms of sensory quality,tobacco leaves treated with the modified treatment featuring the synergistic effect of baking at 120℃,115℃,and 110℃and 4.5%casing application performed better in key aspects such as aroma quality,aroma quantity,off-notes,irritation,and aftertaste,and their comprehensive evaluation was superior to that of other treatment groups.Analysis of physical properties indicated that the modified treatment increased the equilibrium moisture content of tobacco shreds;scanning electron microscopy(SEM)showed that applying 2.5%and 4.5%casing kept the leaf pores open,facilitating the absorption of casing solution,whereas applying 6.5%casing caused pore blockage,preventing complete absorption of the casing solution.Analysis of chemical properties showed that casing had a greater impact on the chemical composition of the leaves than baking intensity.The modified treatment increased the contents of total sugars and reducing sugars,decreased the contents of total alkaloids and total nitrogen,optimized the sugar-to-alkaloid ratio,making it more reasonable.Additionally,the modified treatment increased the total content of aroma-forming substances except neophytadiene and solanone,which was conducive to the accumulation of differential aroma-forming substances(i.e.,14 substances with VIP>1).[Conclusion]In conclusion,the optimal processing conditions are baking temperatures of 120℃,115℃,or 110℃and a 4.5%casing application rate.Leaves processed under these conditions exhibit better overall quality,appropriate chemical component contents,higher aroma-forming substance contents,and excellent sensory quality.关键词
