Taking the double petal red rose as the object, modern precision instrument analysis techniques (GC, GC-MS, IC, HPLC, HPLC-MS, etc.) were used to conduct multi-dimensional research on the functional components and typical flavor substances of the rose, guided by the raw materials, in order to achieve rose analysis Analysis and control of the quality of rose raw materials, using modern fermentation technology as a means, using functional microbial screening and application technology based on rose characteristics, and integrating research on flavor oriented plant-based fermentation mechanisms, to achieve technological empowerment of rose deep processing products Can achieve differentiation and high-end of deep processed products.
