CO2 Extraction Process of Tea Flavor

HOW TO CHOOSE THE RIGHT CO2 EXTRACTOR?

CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessel are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is best for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.

Tea Flavors

Flavors and fragrances are often used in food, cosmetics, medicine, detergent and other industries.

The fragrance can be divided into three types: natural fragrance, natural equivalent fragrance and artificial fragrance.

At present, only a small amount of commercially available flavors are extracted from natural plants and animals, and about 84% of the products are chemically synthesized by traditional production methods in the presence of inorganic catalysts, and their use effects and safety have not been able to meet modern foods.

The development needs of the flavor and fragrance industry cannot guarantee product safety. Therefore, there is an urgent need to find a method for producing natural and safe flavors and fragrances.

Reports

At present, there have been reports on the use of supercritical CO2 to extract flavors in tea, such as:

Yang Jing, “Study on Supercritical Fluid Extraction of Tea Aroma Components”, Food Science and Technology has disclosed a method for supercritical fluid extraction of tea aroma components.

Method, the extraction rate of the tea essential oil obtained by this method reached 2.82%, but the quality of the obtained tea essential oil product (whether it contains other tea biochemical components) was not analyzed, but the aroma components in the tea essential oil were analyzed.

From the analysis results, the content of aroma components is low, only about 1/3.

Another example:

Ren Jian, et al. “Study on Supercritical CO2 Extraction of Fragrant Components of Maojian Tea”, Cereals, Oils and Food Science and Technology, Volume 12, 2004, No. 3, discloses a method for extracting Maojian tea fragrance components by supercritical CO2.

The main purpose of this method is Extract the tea essence and analyze the composition.

The purity of the essence in the obtained tea essential oil is also not high. The caffeine content is as high as 33.82%.

At the same time, impurities such as chlorophyll and lutein are also extracted, making the extracted essential oil darker in color. green. Because the purity and quality of the flavors obtained by the above methods are not high, it is difficult to meet the demand for high-purity natural flavors.
