The product we are introducing is Factory Supply Tannic Acid with CAS 1401 - 55 - 4 and a low price. Tannic acid is a polyphenolic compound. It is usually a yellow - brown amorphous powder or flake. The molecular formula of tannic acid can be generally represented as C₇₆H₅₂O₄₆, and its molecular weight is approximately 1701.20 g/mol. It has a relatively high solubility in water and ethanol, which makes it widely used in various industries.
Tannic acid has a wide range of uses across different industries. In the food industry, it is used as an antioxidant and a clarifying agent. For example, in winemaking, tannic acid can react with proteins in the wine, causing the proteins to precipitate out, thereby clarifying the wine and improving its clarity and stability. In the leather industry, it is a crucial tanning agent. Tannic acid can react with the collagen in animal hides, cross - linking the collagen fibers and making the leather more durable, resistant to decay, and having better feel and appearance. In the pharmaceutical industry, tannic acid has antibacterial, anti - inflammatory, and astringent properties. It can be used in the treatment of skin diseases, such as burns and ulcers, to promote wound healing.
When using tannic acid, proper handling and safety precautions should be taken. In the laboratory or industrial settings, it is necessary to wear appropriate protective equipment, such as gloves and goggles. For food applications, the dosage of tannic acid should comply with relevant food safety regulations. Generally, it is added in a small amount during the manufacturing process according to the specific requirements of the product. In the leather - tanning process, the hides need to be soaked in a tannic - acid solution for a certain period. The concentration of the solution and the soaking time depend on the type and quality of the hides. In pharmaceutical applications, the form of tannic acid, such as ointments or solutions, should be used as directed by a medical professional.
Case 1: Winemaking
A small - scale winery in France was facing the problem of cloudy wine. After adding an appropriate amount of tannic acid during the fermentation process, the proteins in the wine gradually precipitated. After a few weeks of settling, the wine became clear, and its flavor also improved. The tannins from the tannic acid added a certain astringency and complexity to the wine, making it more popular in the local market.
Case 2: Leather Tanning
A leather factory in Italy was processing high - quality cowhide. They used a tannic - acid - based tanning solution. By adjusting the concentration of the solution and the soaking time, they were able to produce leather with excellent softness, strength, and color. The leather was then used to make high - end leather products, such as handbags and shoes, which were well - received by consumers.
