  Australian agriculture supplies many horticultural commodities to domestic
and international markets; however, food composition data for many commodities
are outdated or unavailable. We produced an up-to-date, nationally
representative dataset of up to 148 nutrients and related components in 92
Australian-grown fruit (fresh n=39, dried n=6), vegetables (n=43) and nuts
(n=4) by replacing outdated data (pre-2000), confirming concentrations of
important nutrients and retaining relevant existing data. Primary samples (n =
902) were purchased during peak growing season in Sydney, Melbourne and Perth
between June 2021 and May 2022. While new data reflect current growing
practices, varieties, climate and analytical methods, few notable differences
were found between old and new data where methods of analysis are comparable.
The new data will be incorporated into the Australian Food Composition
Database, allowing free online access to stakeholders. The approach used could
serve as a model for cost-effective updates of national food composition
databases worldwide.
