Problems solved by technology

However, the traditional steam distillation method consumes a lot of energy, takes a long time to extract, and the utilization rate of equipment is low. Due to long-term heating, some components in the essential oil may be decomposed, and at the same time, the plant raw materials will be coked when overheated, which will have a negative impact on the aroma of the essential oil.

Embodiment 1

[0025] Add 100g of cinnamon branches and leaves of 10 meshes into a round bottom flask, add 1000ml of water, add 0.2% sodium dodecylbenzenesulfonate, heat the system to boil, keep it for 3h, transfer the condensate to a refrigerator, and cool it at 10°C 3h, then centrifuge with a centrifugal sedimentation machine at a speed of 6000r / min, centrifuge for 15min, remove the water in the upper layer to obtain crude cinnamon oil, transfer the crude cinnamon oil to a vacuum distillation device, and store it at 80°C with a vacuum of -0.090MPa Distilled under reduced pressure for 30min. 1.65 g of essential oil are obtained.

[0026]

Embodiment 2

[0028] Add 100g of cinnamon branches and leaves of 40 meshes into a round bottom flask, add 800ml of water, add 0.5% TW-80, heat the system to boil, keep for 2h, transfer the condensate to a cold storage, cool at 10°C for 2h, and then use Centrifuge sedimentation with a centrifugal sedimentation machine at a speed of 8000r / min, centrifuge for 10min, and remove the upper layer of water to obtain crude cinnamon oil. The crude cinnamon oil is transferred to a vacuum distillation device, and vacuum distillation is performed at 60°C and a vacuum of -0.095MPa for 30min. . 1.72 g of essential oil are obtained.

Abstract

The invention relates to a method for extracting cinnamon oil from dry branches and leaves of cinnamon. By the method, the extraction time can be shortened, oil yield can be improved, energy consumption can be reduced, and the production cost can be reduced. according to the method, a surfactant is used as a leaching adjuvant in a water vapor distillation method, the water-wetting of surfaces of the branches and leaves of the cinnamon is accelerated under the action of wetting, permeation and solubilization of the surfactant, and the water permeates through plant cells, so that essential oil inside the plant cells is carried away from the cells; and the essential oil is subjected to exchange by heat energy in a system, so that the essential oil is azeotropic with water vapor to be distilled with the water vapor, and the distilled essential oil is condensed, cooled and subjected to centrifugal sedimentation to obtain the cinnamon oil. According to the method, the distillation time is short, so the change of heat sensitive chemical ingredients in the essential oil due to long-term heating is avoided, and the influence on aroma of the essential oil due to the coking of plant raw materials caused by overheating is also avoided. The cinnamon oil is light in color and pure in aroma, and does not have the smell of scorching.

Description

technical field [0001] The invention relates to a method for extracting cinnamon essential oil from dried branches and leaves of cinnamon, in particular to a steam distillation method. Background technique [0002] Cinnamon oil is the volatile oil extracted from the dried bark, leaves or branches of Cinnamon lauraceae. Cinnamon oil has a strong, warm and sweet aroma, with burnt, woody, and ointment aromas. It is an important product of natural spices. Its main component is cinnamaldehyde, which is widely used as food additives and seasonings, and can be directly used as medicine. It is one of the important export products and enjoys a high reputation in the world. Cinnamon oil has strong antibacterial activity against bacteria, fungi, and molds, and can be used as a natural food preservative and grain protectant. [0003] The extraction methods of cinnamon oil include solvent extraction, supercritical CO 2 Extraction, steam distillation, etc. However, because the solvent...
