Tea is becoming increasingly popular as an ingredient in dietary supplements and functional foods. Tea has a complex chemical composition, containing over 2,000 components, consisting of 3.5% to 7.0% inorganic substances and 93% to 96.5% organic substances. There are about 27 inorganic mineral elements in tea, including phosphorus, potassium, sulfur, magnesium, manganese, fluorine, aluminum, calcium, sodium, iron, copper, zinc, selenium, and many others. The organic compounds in tea are mainly proteins, lipids, carbohydrates, amino acids, alkaloids, tea polyphenols, organic acids, pigments, aroma components, vitamins, saponins, sterols, etc. In the last decade, interest in the analysis of tea’s chemical composition has increased dramatically due to the large amount of scientific data showing the positive effects of tea on human health.
Knowledge of the chemical composition of tea helps, on the one hand, to assess its quality and, on the other hand, to monitor and manage the conditions of its growth, processing, and storage. In particular, this knowledge has made it possible to establish the relationship between the chemical composition of tea and its properties by identifying the tea components that determine its aroma and flavor. Therefore, the evaluation of tea quality relies not only on subjective sensory evaluation but also on objective physicochemical methods, especially the determination of the components of tea that are most beneficial to human health.
Lifeasible provides a one-stop platform for tea composition analysis, covering a wide range of black, green, yellow, white, and black teas through a global network of state-of-the-art laboratories. Our solution covers the entire process, from sample processing to data analysis; all you need to do is provide the original sample. We will process and test the samples according to strict standards and ultimately provide accurate test reports.
With our experience, expertise, and state-of-the-art facilities, we offer the following tea composition analysis solutions, including but not limited to：
| Tea Composition Analysis Items | Tea Composition Analysis Items Description |
| Tea Water Leachate Testing | Tea water leachate mainly contains polyphenols, soluble sugars, water-soluble pectin, water-soluble vitamins, free amino acids, caffeine, water-soluble proteins, inorganic salts, etc. We can extract the soluble substances in tea with boiling water under the prescribed conditions and test them to ensure that the water leachate content of your tea meets the local restrictions. |
| Tea Aroma Composition Analysis | The aroma substances in tea are composed of numerous volatile substances with minimal content, different properties, and large differences. Aroma is the main influencing factor in the flavor and quality of tea. We provide cutting-edge analytical and testing techniques to study tea aroma composition and its influencing factors. Our proven aroma extraction technology ensures reliable results of tea aroma analysis. |
| Tea Extracts Testing | Tea extract testing is an essential means to ensure tea products, so the country has set up a strict quality control standard system for tea extracts. We provide many kinds of tea extract testing, including flavonoid and flavonoid glycoside extracts, phenolic acid extracts, polyphenol extracts, terpene extracts, and alkaloid extracts. |
| Tea Fingerprint Analysis | Based on the analysis of volatile components, water-soluble components, and heavy metal components in tea, we established a classification model for different kinds of tea. We used tea fingerprinting and chemical component content as discriminatory indexes to develop a tea quality evaluation system. |
Exploring the chemical composition of tea helps to assess its quality and to control and manage its growing, processing, and storage conditions.
