Effect of A.cristatus on Aroma Production of Cigar Leaf Fermentation
摘要
Abstract
A strain JH was isolated from the surface of Fuzia tea and identified as A.cristatus by morphology and molecular biology.When the water content of the eggplant bottle culture medium was 87.70%,the dry weight of spores in the whole eggplant bottle cultured for 6 d was 0.08 g.The dry weight was 29 times that of spore dry weight in 93.00%moisture medium.A.cristatus was inoculated in tobacco leaves(34%moisture content,the spore inoculum was 0.12 g DW/100 g tobacco leaves)and fermented for 8 days.The total aroma(282.50 μg/g),the content of carotenoid degradation products(212.54 μg/g)and the content of Maillard reaction products(31.16 μg/g)were increased respectively by 38.05%,55.40%and 22.44%compared with 36%moisture content.Compared with the tobacco leaves with 28%moisture content,it also increased respectively by 61.38%,86.11%and 56.90%.In addition,the natural fermentation with uninoculated A.cristatus(34%moisture content)also increased respectively by 52.31%,75.31%and 82.54%.It was descripted that the optimum moisture content of JH was 87.70%in eggplant bottle medium,and the optimum moisture content of JH was 34%in tobacco leaves fermentation,which could significantly improve the aroma content of tobacco leaves.The results provided support for the application of A.cristatus coronatus in the fermentation level of cigar industry.关键词
