Description

Albumin Tannate is a protein-tannin complex formed by the reaction of albumin with tannic acid. This compound is valued for its astringent and protein-precipitating properties, making it a key functional ingredient in specific pharmaceutical and technical applications. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries seeking reliable, high-purity materials for formulation.

Application

• Pharmaceutical Astringent: Used in the formulation of anti-diarrheal medications and topical preparations for its protein-coagulating and mucosa-protecting effects.
• Nutraceutical Ingredient: Employed in dietary supplements designed for gastrointestinal support.
• Clarifying Agent: Acts as a fining agent in beverage processing to remove suspended proteins and polyphenols.
• Protein Precipitation: Utilized in laboratory and bioprocessing workflows for the selective isolation of proteins.
• Tanning & Leather Processing: Serves as an auxiliary agent in specialty leather tanning processes.
• Technical Grade Applications: Used in various industrial processes requiring protein-tannin interactions.
