Highlights
- •
- Kaki fruit samples produced in Spain are generally adequate for essential elements.
- •
- Low levels of potentially toxic elements were found.
- •
- Consume of one pieces per day of kaki fruit involves appropriate mineral intake.
- •
- Mineral profile of kaki fruit samples compared with values found in the literature.
Abstract
The main objective of this study was the determination of the mineral profile of 167 kaki fruit (Diospyros kaki
L.) samples produced from different regions of Spain, including samples
with the protected designation of origin (PDO) ‘Kaki Ribera del Xúquer’
Valencia (Spain). Samples were analysed by inductively coupled plasma
optical emission spectroscopy (ICP-OES) and inductively coupled plasma
mass spectrometry (ICP-MS). Consumption of one piece of kaki fruit
(200–400 g) would give a mineral intake providing 1–10% of the
recommended daily allowance (RDA) for calcium, 1–30% for copper and
potassium, 1–15% from iron and magnesium, up to 1% of sodium, and up to
4% of zinc. ANOVA analysis indicates differences between samples from
different Spanish region, thus offering a way for authentication of PDO
sample origin.
