Embodiment 1

[0016] Add the picked fresh roses to a homogenizer in a ratio of 1:2 after removing stamens and impurities, and weigh 50kg and 8% salt solution, homogenize and pulverize for 3 minutes at a speed of 2000 rpm, and after homogenization Pour the sample into the distillation kettle and soak for 24 hours, heat the steam generator, open the vent valve, and pass water vapor into the distillation kettle at a flow rate of 8L / h to carry out steam distillation. The temperature of the condenser is controlled at 0°C to condense oil and water. Mix the steam, collect the effluent, let the effluent stand at 4°C, and separate the layers to obtain 15 mL of the upper oil, add 1.5 g of anhydrous sodium sulfate, let stand for 24 hours, and filter to obtain 14 ml of rose essential oil. Take off the solution 25L of the lower layer to be rose water.

Embodiment 2

[0018] Add the picked fresh roses to the homogenizer in a ratio of 1:1 after removing stamens and impurities, and weigh 100kg and 12% salt solution, homogenize and pulverize for 1min at a speed of 7000 rpm, and after homogenization Pour the sample into the distillation kettle and soak for 48 hours, heat the steam generator, open the vent valve, and pass water vapor into the distillation kettle at a flow rate of 30L / h to carry out steam distillation. The temperature of the condenser is controlled at -5°C, and the condensation Mix the steam with oil and water, and collect the effluent, let the effluent stand still at 2°C, and wait for layers to obtain 25 mL of the upper layer oil, add 1.25 g of anhydrous sodium sulfate, let stand for 24 hours, and filter to obtain 23 ml of rose essential oil. Get off the solution 100L of the lower layer to be rose water.

Embodiment 3

[0020] Add the picked fresh roses to a homogenizer in a ratio of 1:5 after removing stamens and impurities, and weigh 300kg and 10% salt solution, homogenize and pulverize for 2min at a speed of 5000 rpm, and after homogenization Pour the sample into the distillation kettle and soak for 12 hours, heat the steam generator, open the vent valve, and pass water vapor into the distillation kettle at a flow rate of 60L / h to carry out steam distillation. The temperature of the condenser is controlled at 10°C, and the condensed oil and water are mixed. Steam, and collect the effluent, put the effluent at 0°C, and wait for separation to obtain 81mL of the upper layer oil, add 32.4g of a mixture of anhydrous magnesium sulfate and anhydrous calcium chloride, and let stand for 24 hours. Filter to get rose essential oil 70ml. Get off the solution 180L of the lower layer and be rose water.

Abstract

The invention relates to a method for extracting rose damascana and rose flower water from roses, belonging to the technical field of natural product chemistry. In the invention, the picked fresh roses and saline solution are placed into a pulp refiner with a certain ratio of material to liquid for homogenization and crushing after the stamens of the roses and impurities are removed, the sample is poured into a distillation still for dipping, a vent valve is opened, water steam flow rate is adjusted to carry out steam distillation, the temperature of a condenser is adjusted, oil-water mixed steam is condensed, the flowing-out liquid is collected until the volume of the flowing-out liquid and the weight of rose leaves form a certain proportion, the flowing-out liquid is placed still and layered at low temperature, rose damascana dehydrating agents are added in an upper layer of oil, and then the rose damascana is obtained after being dehydrated; the solution at the lower layer is the rose flower water. Compared with the prior art, the method has the advantages of little loss of top note of the extracted rose damascana, high product quality, simple operation and low production cost.

Description

Technical field: [0001] The invention relates to a method for extracting rose essential oil and rose dew from roses, belonging to the technical field of natural product chemistry. Background technique: [0002] Rose, also known as red rose, is a deciduous shrub in the Rosaceae family. "Food Materia Medica" states that it "mainly benefits the lungs and spleen, nourishes the liver and gallbladder, and the fragrance and sweetness of food are refreshing." Taking it for a long time, the beauty effect is very good. It can effectively eliminate free radicals, eliminate pigmentation, and arouse youthful vitality. Rose essential oil is the king of flower oils and has the reputation of "liquid gold". It has high medicinal and food value. It can activate male hormones, improve skin texture, promote blood circulation and metabolism. And it is the most important and most commonly used precious floral fragrance raw material in spices and fragrances, and is widely used in food, high-en...
