A:​ It uses a dual mechanism. Chemically, the EGCG molecules are hydrophobic; they insert themselves into the lipid bilayer of fat globules. This alters the fat's surface tension. Physically, the tea leaf's natural insoluble fiber matrix acts as a net, trapping these altered fat globules and carrying them through the digestive tract for excretion.

A:​ EGCG has a unique molecular structure (with galloyl groups) that gives it a high affinity for lipid surfaces. Extracts with low EGCG act more like inert fiber. High EGCG ensures the extract actively participates in lipid complexation, rather than just passively adding bulk.

A:​ The interaction is driven by the hydrophobic nature of catechins, particularly EGCG. In an aqueous environment, these molecules orient themselves to shield their non-polar structures from water, which naturally leads them to associate with lipid surfaces. This physicochemical property allows the extract to integrate into lipid micelles during brief contact. We ensure a high concentration of these active compounds so the raw material possesses a strong inherent capacity for lipid interaction, providing formulators with a reliable foundation for their specific applications.

A:​ Our standard extract disperses in water. For enhanced efficacy in high-fat environments, we offer phytosome complexes​ (EGCG bound to phospholipids). This increases EGCG's affinity for oils, making it even more effective at integrating into lipid droplets. Specify your application needs when ordering.

A:​ This is a key benefit often overlooked. The fat-mucilage complexes created by our extract act as a unique prebiotic substrate. While the bound fat is being escorted out, the polyphenol-fiber matrix resists immediate digestion in the upper gut, reaching the colon largely intact. There, it selectively feeds beneficial Bifidobacteriumand Lactobacillusspecies. This promotes a healthier gut environment and supports the Gut-Liver Axis, indirectly aiding long-term lipid metabolism.

A:​ EGCG is sensitive to oxygen, light, and heat. Store in a cool, dry place, tightly sealed. Our packaging includes vacuum-sealed foil bags, often with oxygen absorbers, to ensure a 24-month shelf life.
