Factors influencing the yield of essential oil from the rose flowers are studied both by orthogonal and single factor's analysis experiments. The processing technology for the production of essential oil is put forward. It has been found that the optimized technological parameters are: proportion of water to flowers 4∶1; distilling time 4 h; distilling rate 10 % of the volume of distilling vessel per hour;amount of flowers loaded (75 %) of the volume of distilling vessel;brine concentration 2.5 % to which s...
