Component analysis of extracts from Rosa sterilis and application of enriched MRPs

In order to research the application of Rosa sterilis extracts in tabacco,the volatile flavor components of extracts from Rosa sterilis were analyzed by GC-MS;by using Maillard reaction,enriched MRPs and extracts were obtained.Sensory evaluation and three-point differential test were done for the enriched MRPs and extracts from Rosa sterilis.The results indicate that there are 33 compounds in Rosa sterilis extracts and the majority of compounds are ethyl linolenate(30.70%),ethyl palmitic acid(11.90 %),cinnamic acid(2.73%).The results showed that the fragrance additive and the smoke flavor were harmonious,which could obviously improve the sweetness and smoothness of the flue gas,reduce the irritation,cover the miscellaneous gas and improve the smoke and so on.Three-point differential test showed that there was significant difference between the extract and the enriched MRPs.
