Problems solved by technology

The essential oil extraction rate of the traditional steam distillation method is low (the oil yield of the traditional steam distillation method is generally only 0.15‰~0.3‰), the quality is poor, and the distillation time is long; the organic solvent extraction method needs a large amount (raw material Twice the weight) volatile, flammable solvent, very unsafe, and the purification of the product is also difficult; supercritical CO 2 The extraction method has high requirements for production equipment and a large investment

Embodiment 1

[0014] A method for extracting rose essential oil, the concrete steps are as follows:

[0015] ①Picking: pick the Damascus roses that are not fully open from 5:00 am to 8:00 am;

[0016] ② Preparation of pickling water: add salt and sodium bicarbonate into clear water and stir until completely dissolved. The weight ratio of clear water, common salt and sodium bicarbonate is: 100 parts of clear water, 25 parts of common salt, and 10 parts of sodium bicarbonate;

[0017] ③Marinate: Put the Damascus roses into the pickling bucket, add the pickling water prepared in step ②, the pickling water should submerge all the flowers, seal and store for 3 hours, the pickling temperature is 5-15°C;

[0018] ④Steam distillation: drop the marinated Damascena rose into the still, and add clear water to the still, the weight ratio of Damascus rose and clear water is: 1 part of Damascus rose, 3.5 parts of clear water, the water The steam is passed into the jacket of the distillation kettle to in...

Abstract

The invention provides a method for extracting rose essential oil, which comprises steps: 1 picking; 2 preparation of salted water; 3 salting; 4 distillation of water steam; 5 an oil water mixture which is obtained by cooling through a condenser is guided into an oil water separator, and an oil layer is collected to prepare the rose essential oil after oil and water are fully layered. In the method for extracting the rose essential oil, the salted water which is specially prepared is used for salting rosa rugosa and then steam distillation is performed, and can effectively improve extraction yield and quality of the rose essential oil. The method for extracting the rose essential oil is simple in operation, convenient to master, high in safety, short in distillation time of the water steam, extremely low in energy consumption and low in production cost.

Description
