Abstract
In this study, variations of minerals contents between peel and pulp parts of six different peach varieties originated from Serbia were investigated by using inductively coupled plasma optical emission spectrophotometry and one-way analysis of variance (ANOVA) with Tukey�s post-hoc test. The content of fifteen elements was determined and content of K was highest among macroelements and Fe among microelements in both parts of the peach fruit. Also, peach peel had higher levels of all minerals with the exception of K. Greater differences between the peel and the pulp and the same parts of different types of peaches are observed in the case of macroelements than the microelements. Hg and Cd are not detected while the contents of Pb and As are below prescribed values.
Highlights
In this study, variations of minerals contents between peel and pulp parts of six different peach varieties originated from Serbia were investigated by using inductively coupled plasma optical emission spectrophotometry and one-way analysis of variance (ANOVA) with Tukey’s post-hoc test
Organic acids, phenolic acids, vitamins (C and A), flavonoids and anthocyanin compounds, minerals and dietary fibers are among the major constituents of peach fruits, which contribute to the nutritional quality of both fresh fruits and the juices i.e. these constituents certainly elevate the nutritional status of the peach fruit. 100 g portion of peach fruits should have 165 kJ; 0.91 g of protein; 0.25 g of total lipid; 9.54 of carbohydrate; 8.39 g of sugars; 1.5 g of dietary fiber; 6.6 mg of vitamin C; 88.9 g of water etc
This is present to a lesser extent in the case of comparisons between the contents of these elements in the same part of the fruit of various species: the content of Na and K varies depending on the type of peach while the content of P show the smallest differences between the same parts of different species
Summary
Variations of minerals contents between peel and pulp parts of six different peach varieties originated from Serbia were investigated by using inductively coupled plasma optical emission spectrophotometry and one-way analysis of variance (ANOVA) with Tukey’s post-hoc test. The results of one-way ANOVA analysis with Tukey’s posthoc test show significant differences in the mean content of all investigated macroelements (table 1) between pulp and peel of peach fruits.
