tannins
Our customers love the power of our tannic acids, which have been successfully used in food, animal feed and technical applications for decades. Our tannins are derived from natural sources and have a lower environmental impact than synthetic alternatives.
As a specialist in the extraction of botanicals, Ajinomoto Sustainable Solutions is a world leader in the production of tannic acids and grape seed extracts for a broad range of applications.
Our products
Hydrolysable tannins are far less abundant and only a limited number of plants contain sufficient amounts of these products to be of commercial value. In this family, the distinction between ellagitannins and gallotannins can be made. Wood extracts, like for example oak extract or chestnut extract belong to the group of the ellagitannins.
We are the world leader in the production of gallotannins or tannic acid. Only 4 botanical raw materials can be used for the production of gallotannins:
Aleppo Gallnuts – Quercus infectoria
Chinese Gallnuts – Rhus semialata
Sumac leaves – Rhus coriaria, typhina
Tara pods – Caesalpina spinosa
