The Monitoring of Accumulations of Elements in Apple, Pear, and Quince Fruit Parts.

ABSTRACT

In this study, the distribution of biogenic macro and micro element contents in the peel, pulp, and seeds of some cultivated fruits was observed. The element concentrations of these fruits, which have high commercial value and consumption in the world, were analyzed with ICP-OES. In the "Golden" and "Starking" apple varieties, the lowest and highest calcium amounts were detected in the pulp and seed parts of the fruits, respectively. Additionally, the lowest and highest calcium amounts of pear and quince fruits were found in the seed and pulp and peel and seed parts of the fruits, respectively. Potassium amounts of "Golden" and "Starking" apple parts were established to be between 3585.82 (seed) and 3930.87 mg/kg (pulp) and 3533.82 (peel) and 5671.55 mg/kg (pulp), respectively. Potassium amounts of pear and quince fruit parts were measured to be between 2340.65 (seed) and 5405.97 mg/kg (pulp) and 4455.23 (seed) and 8551.12 mg/kg (pulp), respectively. Iron quantities of the parts of "Golden" and "Starking" apple fruits were established from 4.80 (pulp) and 17.14 mg/kg (seed) to 7.80 (pulp) and 14.53 mg/kg (peel), respectively. While the Fe quantities of pear fruit parts are found to be between 4.51 (pulp) and 15.40 mg/kg (peel), the Fe contents of the parts of quince fruits were determined to be between 5.59 (pulp) and 27.27 mg/kg (peel). Zinc quantities of the parts of pear and quince fruits were recorded to be between 8.43 (pulp) and 12.71 mg/kg (seed) and 0.96 (pulp) and 37.82 mg/kg (seed), respectively. In fruit parts, the highest element was found in the seed, followed by pulp and peel in decreasing order.
