| extraction process | 1) keep 100kg fresh rose in a cool place for 4H; 2) add 500kg of drinking water in the distillation kettle, adjust the pH value to 3.0 with commercial grade hydrochloric acid, add 0.25kg of commercial grade cellulase into the water, stir evenly, put 100kg of rose in step 1), in order to destroy the cellulose and pectin of rose plant tissue by biological enzymes, so as to open the channel of rose plant tissue, which is conducive to the entry of water vapor into the cell and the rose oil out, thereby improving the yield; 3) steam is introduced into the jacket of the distillation kettle to heat the solution in the distillation kettle to 35 ℃ for 2.5h, so as to activate the biological activity of the enzyme by raising the temperature and keeping the temperature, let it give full play to the enzymatic hydrolysis, so that the water vapor smoothly enters the cell and the rose oil is brought out; 4) the steam is introduced into the distillation kettle according to the conventional method, and the solution in the distillation kettle is heated to 60 ° C, at the same time, the vacuum of the distillation kettle is evacuated to a vacuum degree of 0.8 Mpa, and the vacuum steam distillation is carried out, so that the rose oil can be quickly extracted at low temperature and under reduced pressure, and the original components and aroma of rose oil can be maintained as much as possible, and the rose oil can be improved. The distillate is collected, cooled and placed until the separated oil layer and slip-out liquid; 5) add salt to the slip-out liquid in step 4) until the mass concentration of salt is 15%, after stirring until the salt is dissolved, freeze it at -10 °c for 3H to reduce the solubility of rose oil in water, and separate the oil layer and slip out liquid; 6) step 5) the distillate returns to step 2) to participate in distillation, so as to make full use of the distillate containing salt and reduce the solubility of rose oil in water; 7) merge the oil layers of steps 4) and 5), 35.5g rose oil was obtained, and the yield was 0.036%. Compared with the rose oil obtained by the conventional water vapor method (the yield was 0.015 ~ 0.025%), the yield was high, which was 1.44 times of the conventional yield, the aroma is excellent and the taste is very thick. |

| production method | some roses from Rosaceae (e. G., German rose Rosa gallica, Damascene Rose R.Damascena, White Rose R.Alba, Louver Rose R.Centifolia et al) fresh flowers were obtained by steam distillation. The yield was 0.03%-0.05%. The components are mainly citronellol, geraniol and linalool; The flowers are also fermented in salt solution first, then by steam distillation, the components dissolved in the distillate are adsorbed by activated carbon, and finally desorbed by ether, the yield can reach 0.07% ~ O.10%. The main component is phenyl ethyl alcohol, and the quality is poor. Mainly produced in Bulgaria, France, Egypt, Turkey, Iraq and the former Soviet Union and other countries. Flowers from Rosaceae Bush rose (Rosa damascerla et al.) are extracted with 1:2 petroleum ether by cold method, and the filtered oil-water mixture is concentrated by pressure often, and then (1.33~1.6) x104pa (100 ~ 0.2% mmHg) vacuum concentration (temperature does not exceed 50 Deg C) obtained, the yield of about. With Rose extract as raw material, add 10 times the amount of ethanol, 20 deg C immersion 8~10h, filter undissolved wax (rose wax), the ethanol solution was cooled to -18 °c, and filtered at -18 °c to separate the secondary wax, then used at normal pressure, then at 5306 ~ 6599Pa(39.8~49.5mmHg). Ethanol was distilled off under vacuum (temperature not exceeding 50 ° C.). |
