GARCIA-AMOEDO, Luis Henrique  and  ALMEIDA-MURADIAN, Ligia Bicudo de. Physicochemical composition of pure and adulterated royal jelly. Quím. Nova [online]. 2007, vol.30, n.2, pp.257-259. ISSN 0100-4042.

The physicochemical composition of pure royal jelly as well as of some adulterated samples was analyzed by determining moisture, ash, lipids, nitrogen/proteins, carbohydrates, starch and 10- HDA (10-hydroxy-2-decenoic acid). The solubility in alkaline medium was used to detect the main frauds for adulterating royal jelly which comprise addition of yogurt, water, egg white, sweet condensed milk mixed with propolis, unripe banana and corn starch slurry.

Keywords : adulteration; royal jelly; beehive products.
