Bee Propolis

Bee propolis is the resinous material that honey bees collect from tree buds and plant exudates and blend with beeswax to seal their hives. It is a complex mixture rich in flavonoids and phenolic acids. Nustras supplies propolis as a concentrated extract powder, water/ethanol extracted, in a standard extract ratio and in flavonoid-standardised grades.

Propolis extract is formulated into capsules and tablets, lozenges and throat sprays, tinctures and liquid supplements, functional foods, oral-care products such as toothpastes and mouthwashes, and cosmetics including creams, balms and soaps.

The material is a brown to yellowish-brown powder with a characteristic resinous odour. Flavonoid content is standardised to specification and determined by UV-VIS spectrophotometry, with identity confirmed by thin-layer chromatography or HPLC; extract ratio, loss on drying, residual solvents, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies bee propolis extract of Chinese origin in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Propolis is an accepted supplement and food ingredient in major markets; buyers confirm the permitted level and claim for their application. Contact us for grade, pricing per kilogram and lead time.
