Amino acid composition and organoleptic properties of pollen loads infested with stored product mites under controlled laboratory conditions were studied. Three mite species were considered (Tyrophagous putrescentiae, Carpoglyphus lactis, Glycyphagus domesticus); changes occurring in the pollen were studied at three initial infestation levels (0 - control, 20 and 80 mites) in 1 kg of pollen, and three duration times of pollen exposure to mites (1,5, 3 and 12 months). Reduction in quality was found in mite-infested pollen compared to pollen loads free of mites which consisted in decreased amino acid content, including essential amino acids, as well as in substantial adverse changes in odour, flavour, colour and consistence of the product
