Problems solved by technology

At present, the large-scale extraction method of Litsea cubeba essential oil is steam distillation, which is to pass high-temperature steam into the suspension of Litsea cubeba, and after the suspension is boiled, a mixed steam containing water vapor and Litsea cubeba essential oil is generated, and the steam is condensed After that, the water-insoluble Litsea Cubeba essential oil can be obtained. When the Litsea Cubeba Essential Oil is all steamed out, the kettle is opened to discharge the slag....

Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiment, but does not constitute any limitation to the present invention.

[0011] A method for reducing the chromaticity of waste liquid in litsea cubeba essential oil, mainly comprising the following steps:

[0012] Step 1, adding immobilized cellulase and immobilized glucanase to the waste liquid extracted from Litsea cubeba essential oil and stirring, the amount of the immobilized cellulase is 1 to 40% of the weight of waste liquid extracted from Litsea cubeba essential oil %, the amount of the immobilized glucanase is 1-40% of the weight of litsea cubeba essential oil extraction waste liquid, and the stirring time is 1-120 minutes;

[0013] Step 2. Add immobilized glucose oxidase to the mixed solution treated in step 1, stir, and then let it stand. The amount of the immobilized glucose oxidase is 1-40% of the weight of the mixed solution, and the stirring time is 1-40%. 120 minutes, and t...

Abstract

The invention discloses a method for reducing the chromaticity of waste liquid in litsea cubeba essential oil, and the method mainly comprises the following steps: 1, adding immobilized cellulase andimmobilized glucanase into litsea cubeba essential oil extraction waste liquid, and performing stirring, wherein the amount of the immobilized cellulase is 1-40% of the weight of the litsea cubeba essential oil extraction waste liquid, the amount of the immobilized glucanase is 1-40% of the weight of the litsea cubeba essential oil extraction waste liquid, and the stirring time is 1-120 minutes; and 2, adding immobilized glucose oxidase into the mixed solution treated in the step 1, performing stirring for 1-120 minutes, and conducting standing for 30-1040 minutes, wherein the amount of the immobilized glucose oxidase is 1-40% of the weight of the mixed solution. The method has simple production and processing steps, is convenient to operate, can effectively reduce the chromaticity of thewaste liquid in the litsea cubeba essential oil, the processing cost is greatly reduced, and the product quality is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction, in particular to a method for reducing the chroma of waste liquid in litsea cubeba essential oil. Background technique [0002] Litsea Cubeba is a rich natural plant resource rich in citral in my country. Litsea cubeba essential oil has always been a natural plant essential oil with the largest export volume in my country. At present, the large-scale extraction method of Litsea cubeba essential oil is steam distillation, which is to pass high-temperature steam into the suspension of Litsea cubeba, and after the suspension is boiled, a mixed steam containing water vapor and Litsea cubeba essential oil is generated, and the steam is condensed After that, the water-insoluble Litsea Cubeba essential oil can be obtained. When the Litsea Cubeba Essential Oil is all steamed out, the kettle is opened to discharge the slag. At this time, a large amount of yellow waste liquid will be produ...
