| stable isotope and trace element profiling combined with classification models to differentiate geographic growing origin for three fruits: effects of subregion and variety. | classifications of geographic growing origin of three fresh fruits combining elemental profiles with various modeling approaches were determined. elemental analysis (ca, cd, cr, cu, fe, k, mg, mn, na, ni, p, v, and zn) of strawberry, blueberry, and pear samples was performed using inductively coupled plasma argon atomic emission spectrometer. bulk stable carbon and nitrogen isotope analyses in pear were performed using mass spectrometry as an alternative fingerprinting technique. each fruit, str ... | 2006 | 16786991 |
