Phytosterol esters

Phytosterol esters are formed by esterifying plant sterols (e.g., beta-sitosterol, campesterol, stigmasterol) with fatty acids, typically from vegetable oils. This modification dramatically improves oil solubility, making them the preferred form for incorporating plant sterols into lipid-based food, beverage, and supplement applications. Our phytosterol esters are produced under controlled conditions, with total sterol content ≥ 95% and a low free sterol fraction to ensure stability and consistent performance.

Supplied as a white to off-white powder or waxy solid, this product is designed for formulators who need a reliable, cost-effective way to deliver cholesterol-lowering benefits in functional foods and dietary supplements. Each batch is accompanied by a certificate of analysis, and we can provide technical support for dosage and formulation.
