Embodiment 1

[0015] Crush the dried cinnamon bark, add ethanol (70%) which is 1 times the weight of cinnamon bark, mix well, and process it under microwave conditions with a power of 200W for 20s, then recover the ethanol from the microwave-treated mixed material, and put it in a distillation still Add 6 times the weight of cinnamon bark and 0.1% fatty alcohol polyoxyethylene ether of the weight of water, distill for 1 hour at a vacuum of -0.095MPa and a temperature of 50°C, collect the distillate, and distill at 4 Stand still at ℃ for 20 hours, centrifuge to precipitate, and separate oil and water to obtain cinnamon oil. The extraction rate of cinnamon oil was measured to be 1.81%.

Embodiment 2

[0017] Crush the dried cinnamon bark, add ethanol (90%) which is 1.4 times the weight of cinnamon bark, mix well, and process it under microwave conditions with a power of 800W for 25s, then recover the ethanol from the microwave-treated mixture, and put it in a distillation still Add 12 times the weight of cinnamon bark and 1% sorbitan fatty acid ester of the weight of water, distill for 1.5 hours at a vacuum of -0.080MPa and a temperature of 80°C, collect the distillate, and Stand at 20° C. for 10 hours, centrifuge to precipitate, and separate oil and water to obtain cinnamon oil. The extraction rate of cinnamon oil was measured to be 1.89%.

Embodiment 3

[0019] Crush the dried cinnamon bark, add ethanol (80%) 1.2 times the weight of the cinnamon bark, mix well, and process it under microwave conditions with a power of 600W for 22s, then recover the ethanol from the microwave-treated mixed material, and put it in a distillation still Add 8 times the weight of cinnamon bark and 0.5% sodium dodecylbenzenesulfonate of the weight of water, and distill for 1.2 hours at a vacuum of -0.090MPa and a temperature of 65°C to collect the distillate. Stand at 10° C. for 6 hours, centrifuge to precipitate, and separate oil and water to obtain cinnamon oil. The extraction rate of cinnamon oil was measured to be 2.1%.

Abstract

The invention discloses an extraction process of cinnamon oil. The process comprises the following steps of: crushing cinnamon bark which is aired in the shadow, adding ethanol equal with the weight being 1-1.4 times that of the cinnamon bark, uniformly mixing, processing for 20-25 seconds under a microwave condition, putting the mixture subjected to microwave processing into a distillation still after recycling the ethanol, adding water and a surfactant, carrying out reduced pressure distillation for 0.5-1.5 hours, collecting distillate, standing for 2-10 hours at 4-20 DEG C, and carrying out centrifugation and oil-water separation to obtain the cinnamon oil. According to the extraction process of the cinnamon oil, the cinnamon bark is preprocessed by utilizing microwaves, and cell tissues of the cinnamon bark can be damaged, so that the subsequent distillation time is greatly shortened, and the influence on the product quality caused by the decomposition of thermosensitive substances due to long-time heating is avoided; and the product prepared by utilizing the extraction process is light in color, pure in fragrance and good in quality.

Description

technical field [0001] The invention relates to a process for extracting spices, in particular to a process for extracting cinnamon oil. Background technique [0002] Cinnamon oil is the volatile oil extracted from the dried bark, leaves or branches of Cinnamon lauraceae. It has a strong, warm and sweet aroma, with burnt, woody and creamy aroma. Cinnamon oil contains many important functional components, more than 80% of which are cinnamaldehyde, in addition, it also contains more than dozens of components such as cinnamyl alcohol, cinnamic acid, coumarin, cinnamon acetate, acetophenone, etc., which can be used as a natural Fragrances, antioxidants, bacteriostats and preservatives. Therefore, it can be widely used in food, medicine, chemical industry and other industries. [0003] The extraction methods of cinnamon oil include solvent extraction, supercritical CO 2 extraction and steam distillation. Solvent extraction requires a large amount of flammable and explosive or...
