FUNCTION

Broad-spectrum Antibacterial

The most prominent feature of grapefruit extract is its broad‑spectrum inhibitory activity against bacteria, fungi, viruses, and parasites. This antimicrobial efficacy is primarily attributed to its naturally low pH, which creates an unfavourable environment for pathogens, and its rich polyphenol content, which disrupts microbial cell membranes and inhibits enzyme function.

Antioxidant

Grapefruit Seed Extract Powder (GSE) is rich in polyphenols such as flavonoids and phenolic acids, which provide potent antioxidant capacity by scavenging free radicals. This protective effect helps shield cells from oxidative damage, thereby supporting overall cellular integrity and reducing the risk of chronic diseases.

Application

Medical and personal care

In skincare, Grapefruit Seed Extract Powder (GSE) serves as a natural antimicrobial agent for skin disinfection and is incorporated into acne‑removing formulations to reduce bacterial proliferation and inflammation. In oral care, it is added to mouthwashes to inhibit plaque‑forming bacteria, freshen breath, and support overall oral hygiene, offering a plant‑based alternative to synthetic antiseptics.

Food industry

Grapefruit Seed Extract Powder (GSE) can take advantage of its broad-spectrum antibacterial property to be sprayed or added to food to inhibit the growth of microorganisms and extend the shelf life. It is a natural preservative.
