Tannins Analysis Services
Tannins are a complex group of chemicals classified as phenolic compounds. They are commonly found in food grains such as sorghum, barley, dry beans, faba beans, peas, pigeonpeas, winged beans, and others. Fruits such as apples, bananas, blackberries, dates, grapes, peaches, plums, raspberries, and strawberries also contain an appreciable quantity of tannins[1]. As secondary metabolites, tannins help protect plant species. For example, tannins stored in the bark can protect the tree from bacterial and fungal infections.
Tannins are used in tanning leather, dyeing fabric, making ink, feeds, fisheries, and beverages. They are also used in the clarification of wines and beers, as a constituent to reduce the viscosity of drilling mud for oil wells, and in boiler water to prevent scale formation. Due to their styptic and astringent properties, tannins have been applied to treat tonsillitis, hemorrhoids, pharyngitis, and skin eruptions. What's more, tannins act as antioxidants, helping to prevent and reverse cellular damage caused when free radicals attack our cells. Alfa Chemistry has advanced analytical instruments to provide professional tannins analysis services.
Our Service Scope
Alfa Chemistry is a leading company that focuses on providing high quality customer service. Our highly skilled Ph.D. and M.S. biochemists will help you solve any analytical problems in your research. Our advanced and flexible technology platforms enable us to offer a full range of tannins analysis services. Our analysis scope is as follow.
Hydrolysable tannins
Hydrolysable tannins are an important group of plant secondary metabolites that include gallotannins and ellagitannins. Gallotannins are mainly extracted from tara, sumac and gallnuts. Ellagitannins are mainly extracted from oak wood, chestnut wood and myrobalan. Alfa Chemistry offers hydrolysable tannins analysis services to customers.
Condensed tannins
Condensed tannins are mainly obtained by water extraction from wood and bark. They are further divided into proanthocyanidins and profisetinidins. Proanthocyanidins are mainly diffused in the skins and seeds of grapes, so they can be found in red wines. Profisetinidins are extracted from quebracho wood. Alfa Chemistry offers condensed tannins analysis services to customers.
