Tannic Acid Analysis Service

Tannic acid is a specific form of tannin, a type of polyphenolic compound that is widely distributed in the plant kingdom. It is primarily derived from sources such as oak bark, gallnuts, and various other plants. Tannic acid has a complex structure, typically composed of a glucose core with multiple galloyl ester groups, which contribute to its astringent properties and high affinity for proteins.

 

Tannic acid is categorized into two main types: hydrolyzable tannins and condensed tannins. Hydrolyzable tannins, including gallotannins and ellagitannins, can be broken down by hydrolysis into sugars and phenolic acids. Condensed tannins, also known as proanthocyanidins, are polymers of flavonoid units and do not readily hydrolyze.

In the food and beverage industry, it is used as a clarifying agent, flavor enhancer, and antioxidant. In the pharmaceutical and nutraceutical sectors, tannic acid is valued for its antimicrobial, anti-inflammatory, and antioxidant properties, which make it a potential therapeutic agent for various diseases. Moreover, tannic acid finds use in the leather industry for tanning processes and in the production of inks and dyes due to its strong binding affinity for proteins and metal ions.

 

Technical Principles

We utilize High-Performance Liquid Chromatography coupled with Mass Spectrometry (HPLC-MS), one of the most powerful analytical techniques for metabolite profiling. This approach allows us to accurately quantify tannic acid and identify its metabolic pathways in various biological samples.
