Analysis of Hive Products

As a natural bee product, propolis varies greatly in its composition depending on its geographical and botanical origin. Propolis is rich in secondary plant substances like polyphenols (for example phenolic acids and flavonoids) that are responsible for its biological activity. Furthermore, raw propolis is known to accumulate considerable amounts of pesticides as well as heavy metals.

Intertek offers various analyses for both raw propolis and products associated with propolis, for example dry extracts and alcoholic liquid extracts. 

Royal jelly is well known for its content of 10-Hydroxy-2-decenoic acid (10-HDA), which is a bio-active compound and one of the major quality parameters for royal jelly. Like other bee products, royal jelly has to be free of antibiotic residues and has to comply with the relevant scientific literature. 

Intertek offers a wide range of tests in order to assure the quality of this bee product, including analyses mentioned in the current ISO standard on royal jelly specifications. 

Due to the wide variety of pollen, the common quality criteria like moisture, protein and ash vary considerably. Authenticity testing of pollen is usually performed by microscopy in order to verify the botanical and geographical origin.

Intertek also provides the testing of pollen on residues of antibiotics and pesticides as well as contaminants including pyrrolizidine alkaloids. 

As beeswax is often subject to adulteration, its main quality and authenticity should generally be verified. In particular, the total hydrocarbon content as well as the drop point and the so-called key figures for beeswax, are typical analysis parameters for this purpose. Due to their physicochemical properties, fat-soluble residues of pesticides and antibiotics can accumulate in beeswax. Furthermore, the specification of Regulation (EU) No 231/2012 have to be considered if beeswax is to be used as a food additive.

The experts at Intertek can assist with all your beeswax analysis requirements.
