Spent coffee grounds (SCGs) are a food waste with a large generation around the world.
However, their utilization as a soil organic amendment is difficult due to their phytotoxic effect. In
the present work, the impact of agronomic biofortification on Dutch cucumbers was studied by using
different chemically modified SCGs, analyzing their effects on Zn content, the release of antioxidant
capacity and the production of short-chain fatty acids after in vitro digestion–fermentation. The
results indicated variations in the Zn content and chemical composition of cucumbers according
to the treatment groups. The functionalized with Zn and activated SCGs were able to increase Zn
levels in cucumbers. Meanwhile, the activated hydrochar obtained at 160 ºC and the activated
and functionalized with Zn SCGs showed the highest Zn supply per serving. Differences in the
antioxidant capacity and short-chain fatty acid production were observed between the groups. It
is concluded that the growing conditions and the presence of Zn may significantly influence the
contribution of these cucumbers to the dietary intake of nutrients and antioxidants, which could have
important implications for human health and nutrition.
