Problems solved by technology

It is reported in the literature that the essential oil content in bergamot is up to 1.6% (mass percentage). In the prior art, its extraction and separation techniques mainly include pressing, steam distillation, solvent extraction, simultaneous distillation-extraction and supercritical extraction. There are still many technical problems that need to be solved in these methods, such as the low extraction efficiency of the cold pressing method; the relatively high temperature required by the steam distillation method will destroy the heat-sensitive substances in the essential oil, resulting in the loss of low boiling point components. However, high-boiling point components are not easy to evaporate, which affects the integrity of the aroma; from the perspective of refining equipment, most of them follow the traditional distillation equipment, and the old-fashioned experimental equipment is used in design, and there is still room for improvement

Embodiment Construction

[0025] The invention provides a new refining facility for bergamot essential oil to realize an integrated system integrating enzymolysis, squeezing and rectification; and the refining process of enzymolysis+pressing+rectification.

[0026] Below, it will be described in detail in conjunction with the relevant drawings

[0027] 1. New technology of essential oil extraction

[0028] Because the essential oil is distributed in the cell membrane of bergamot, it is protected by the cell wall layer, and the wall must be broken in order to make it free. However, the current extraction method is insufficient in terms of breaking the cell wall, and the content of cellulose and pectin in the cell wall is relatively high, close to 10%, and contains a small amount of protein.

[0029] refer to figure 1 , the present invention adopts the composite extraction process of enzymolysis→pressing→steam distillation. Cellulase, pectinase and acid protease were selected for enzymatic hydrolysis....

Abstract

The invention provides an extraction method, equipment and application of bergamot essential oil. The method comprises the following steps: 1) crushing a bergamot raw material, adding water accordingto the weight ratio of the raw materials to water of 1: 3 to 1: 10, and squeezing; 2) taking a mixed enzyme of cellulase, pectinase and acid protease, adding enzyme powder according to the addition ratio of 0.5 to 5 IU of the mixed enzyme per 1g of the bergamot raw material, and carrying out enzymolysis; and 3) carrying out steam distillation.

Description

technical field [0001] The invention relates to an extraction method, equipment and application of bergamot essential oil. Background technique [0002] Bergamot (Citrus medical var. sarcodactylis) is the fruit of the Rutaceae citrus plant, also known as Miluo orange, Fushou orange and so on. Because the top of the fruit is split, opened or fisted, shaped like the hands of Guanyin, people are used to calling it bergamot. Its taste is fragrant and elegant, and it is an important precious spice plant. The main components of bergamot volatile essential oil are terpenes, sesquiterpenes, higher alcohols, aldehydes, ketones, esters and other physiologically active substances. It has the effect of relieving pain, and also has the effects of expectorant, cough, asthma, antibacterial and anti-inflammatory. In addition to the application of bergamot essential oil in medicinal materials, it is also widely used in cosmetics, food and other fields. [0003] According to reports, ever...
