EDS Analysis for Fruit Prunus Elemental Composition Determination

摘要

The questions of the practical usage of the analytical scanning electron microscope JSM 600 LA by JEOL Company (Japan) with EDS system - microanalysis were envisaged. This device was used to study the structure and elemental composition of the fruit ash received from 6 breeds of 3 plum species. Plums are rich in mineral substances, the following order of substances accumulation is characteristic for them: K > P > Ca > Mg > Na = S > Fe > Zn ~ Cu > Mn = Co > Pb. K is accumulated on 7 - 20 % more in the plum fruit pulp than in the plum fruit skin. The concentration of Ca, Cu, Fe, Ni, Zn and Pb in fruit skin is in 2 - 10 times higher than in pulp. The most of mineral substances is accumulated in the fruit of Prunus salicina L. plum specie. The significant correlations are determined between the accumulation of Ca and Mg (r 0.75) and Ca and Ni (r 0.71); the medium correlation is indicated between the accumulation of Ca and Cu (r 0.62) and Cu and Ni (r 0.55).
