Preparation of Kushui Rose pure oil and its application in cigarette
In order to investigate the application of Kushui Rose extract in cigarette flavoring,supercritical CO2 extraction technology was used to extract Kushui Rose absolute from rose extract,with orthogonal experiments in optimizing the extraction conditions of Kushui Rose absolute.The samples of rose absolute were analyzed by chromatography-mass spectrometry(GC/MS),with the sensory evaluation results followed.The results showed that,(1)The optimized experimental conditions in supercritical CO2 extraction of Kushui Rose absolute were extraction pressure 30 MPa,temperature 50℃,time 2.5 h.with the highest yield of 5.63%.(2)A total of 55 aroma components were detected in the oil sample,including 19 alcohols,7 esters,7 terpenes,and 7 aldehydes,7 aliphatic hydrocarbon,and the main aroma components included linalool,nerol,geraniol,phenylethyl acetate,methyl eugenol,etc.(3)The sensory evaluation results suggested that Kushui Rose absolute could effectively improve the aroma and quality of cigarettes.(4)The appropriate fragrance ratio for the rose absolute in this cigarette is 0.000 5%-0.015 0%through relevant cigarette flavoring tests.
