Caffeic Acid Powder

Product Introduction:

Caffeic acid powder is a naturally occurring organic compound belonging to the hydroxycinnamic acid family. Presenting as a yellow crystalline solid, it features both phenolic and acrylic acid functional groups. Ubiquitous in the plant kingdom, it functions as a key intermediate in the biosynthesis of lignin—a vital structural polymer found in woody plant tissues and agricultural by-products.

Storage and Transportation:

For bulk quantities, store in tightly sealed, airtight containers in a cool, dry environment to maintain stability and prevent degradation.

Benefits:

Caffeic acid powder has demonstrated superior antioxidant activity, surpassing other compounds in suppressing aflatoxin production by over 95%. Research indicates it effectively inhibits oxidative stress—the key trigger for Aspergillus flavus-induced aflatoxin synthesis—offering promising applications in natural antifungal strategies, such as enriching crops or trees with bioactive antioxidants.
Additionally, studies reveal that its derivative, CAPE (caffeic acid phenethyl ester), plays a significant role in modulating acute immune and inflammatory responses, suggesting strong potential as a therapeutic agent for managing chronic inflammation.

Applications:

(1) Serves as a potent ingredient in anti-infectious formulations
(2) Exhibits broad-spectrum antiviral and antibacterial properties
(3) Characterized by low toxicity and minimal side effects
(4) Delivers powerful anti-infective outcomes
(5) Due to its efficacy, it is not only valuable in pharmaceutical development but also widely applicable across food, feed additives, and cosmetic industries for its safety and functionality
