Abstract
Vitamin K is emerging as a multi-function vitamin that plays a role in bone,
brain and vascular health. Vitamin K composition data remain limited globally
and Australia has lacked nationally representative data for vitamin K1
(phylloquinone, PK) in horticultural commodities. Primary samples (n = 927) of
90 different Australian-grown fruit, vegetable and nut commodities were
purchased in three Australian cities. We measured PK in duplicate in 95
composite samples using liquid chromatography with electrospray
ionisation-tandem mass spectrometry. The greatest mean concentrations of PK
were found in kale (565 ug/100 g), baby spinach (255 ug/100 g) and Brussels
sprouts (195 ug/100 g). The data contribute to the global collection of vitamin
K food composition data. They add to the evidence that PK concentrations vary
markedly between geographic regions, supporting development of region-specific
datasets for national food composition databases that do not yet contain data
for vitamin K.
