Extraction process of cinnamon oil

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...

AI Technical Summary

Problems solved by technology

The solvent extraction method requires a large amount of flammable and explosive organic solvents, which has certain safety hazards, and there is a certain amount of solvent residue, which affects product quality

Supercritical CO 2 The extraction method requires a high-pressure environment, high requirements on equipment, large investment in equipment, limited production capacity, unable to form industrialized large-scale production, and high product cost

The steam distillation method has the advantages of simple equipment, simple operation, low cost, and large output. However, since the cinnamon oil in the cinnamon bark is mainly embedded in cells, the extraction rate of the cinnamon oil directly obtained by the steam distillation method is low, and due to cooking If the time is too long, the energy consumption is high, and the heat-sensitive components are easily decomposed, especially the most important contributor to the characteristic aroma of cinnamon oil-cinnamaldehyde has poor thermal stability and is easily decomposed, which affects the quality of the product
