Comparison of Mineral Contents of Organically and Conventionally Grown Red Potatoes (solanum Tuberosum) Using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)

Résumé du livre

A study was undertaken to analyze the abundance of seven nutritionally relevant minerals in organically and conventionally grown red potatoes commercially available in the greater Provo/Orem area, Utah. Sixteen redskin potatoes were purchased from four conventional and four organic potato sellers selected from a randomized list of all vendors of potatoes in Provo and Orem. The 128 potato samples were washed, skinned, cut, oven dried, milled with an IKA M 20 Universal Mill, acid digested in a microwave accelerated reaction system, and analyzed with an inductively coupled plasma optical emission spectrometer. Concentrations of the seven elements calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), sodium (Na) and zinc (Zn) were determined with a five-point calibration curve.
