BACKGROUND: Minerals are essential for human nutrition and must be obtained from our diet. Crucifer vegetables are a good source of these nutrients. Our objectives were to determine the genetic variability for mineral content and to evaluate the use of near-infrared reflectance spectroscopy (NIRS) for prediction of ashes and minerals among and within the rocket species Eruca vesicaria subsp. sativa and vesicaria. The minerals studied were iron (Fe), copper (Cu), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), manganese (Mn) and zinc (Zn).
RESULTS: The maximum mean values obtained for all the accessions (mean ± SE) were 235.5 ± 1.5 mg ashes kg−1, 273.3 ± 4.2 mg Fe kg−1, 18.1 ± 0.4 mg Cu kg−1, 2.8 ± 0.1 g Na kg−1, 71.6 ± 1.0 g K kg−1, 64.6 ± 1.2 g Ca kg−1, 6.8 ± 0.1 g mg kg−1, 101.6 ± 1.2 mg Mn kg−1, and 67.1 ± 0.4 mg Zn kg−1 of dry weight.
CONCLUSION: The statistical analysis showed significant differences for all the minerals, except Ca, for each accession studied individually and for accessions grouped within countries. The results indicate that NIRS can be used as a rapid screening method for determining total mineral, Fe, Na, K, and Zn in rocket. Copyright © 2011 Society of Chemical Industry
