Apple is one of the fruits that has beneficial effects on human healthy diet and
life. The aim of this study is to determine some physical, mineral and organic acids composition
of apple cultivars grown in different locations throughout Lorestan province. Apple
cultivars had been harvested from different locations throughout Lorestan province of Iran. Analyses for 3
elements (Iron, Zinc, and calcium) were conducted by the flame atomic absorption spectrometry. Phosphorus
was measured by the UV-Vis spectrophotometer and Sodium and Potassium were measured by the flame photometer.
Organic acids were determined by Titration method using NaOH and phenolphethalein indicator.
Weight was measured by scale based on 0.1 g and length and diameters were measured by caliper. The mean
weight of Red Delicious and Golden Delicious apples was 173.7 g and 146.7 g, respectively. The amount of
iron, zinc, calcium, phosphorus, sodium, and potassium for the red variety was 0.24, 0.14, 28, 8.9, 4.7 and
63.8 respectively; values for the Golden variety were 0.23, 0.14, 27.9, 8.8, 4.5, and 66.3 mg/100g fresh
weight, respectively. The amount of ascorbic acid, malic acid, and citric acid for Golden delicious was 9.09,
0.27 and 0.28, respectively; for Red delicious apples, the amount was 9.47, 0.26 and 0.28 mg/100 g, respectively.
Acidities for Golden delicious and Red delicious were 3.7 and 4, respectively. One hundred gram of
apple fruit grown in Lorestan would provide 3% of iron, 1.5% of zinc, 2.8% of calcium and 1.4% of potassium
requirements. The amount of organic acid in apples of Lorestan province was lower than some other
