Description

Gum Guaiac is a natural oleoresin obtained from the wood of the *Guaiacum officinale* tree, valued for its unique chemical properties and historical significance. This product matters for its role as a natural antioxidant and colorimetric indicator, particularly in detecting peroxides and oxidative rancidity. Industries that need it include food & beverage, pharmaceutical, and industrial manufacturing, where it serves as a critical reagent and preservative agent.

Application

• Antioxidant in Food & Fats: Used to prevent rancidity in edible oils, fats, and meat products.
• Pharmaceutical Excipient: Employed as a tablet binder and in traditional medicinal preparations.
• Chemical Indicator: Serves as a sensitive reagent for the detection of blood (heme), peroxides, and oxidative enzymes like peroxidase in laboratory tests.
• Flavoring Agent: Approved for use as a natural flavoring substance in foods and beverages.
• Industrial Preservative: Applied in cosmetics and personal care products for its antioxidant properties.
• Research & Development: Utilized in biochemical assays and as a model compound in studies of natural resins and antioxidants.
