Title: EVALUATION AND DETERMINATION OF MINERALS CONTENT IN FRUITS
Abstract: Minerals are important in human nutrition, some play essential role in bone making others are important in body maintenance or metabolic; some of minerals are part of enzyme molecules. To determine mineral content of donat peach, apple, pear, plum and nectarine 10 g of each weighted then burned in 550 °C. Obtained ash was used to measure different types of minerals which have important functions in the body they are calcium, phosphorus, iron, potassium and sodium. Dry matter content of samples was determined according to AOAC method. Results showed that among analyzed fruits nectarine has highest ash content as % 0.54 on the other hand the lowest ash content belongs to pear (%0.34) other fruits has similar ash content. Analysis indicated that calcium content of peach is the lowest (600 mg/100g) but peach has the highest content of potassium (0.273 mg/100g) and iron (228.4mg/100g). The highest phosphorus content measured in apple (33 mg/100g) although apple had lowest sodium content (134.9 mg/100g). Highest ash content of nectarine may be due to high calcium content of this fruit (1240 mg/100g) but nectarine had lowest potassium content (115.2 mg/100g). Consumption one serve of nectarine or two serves of peach a day can provide human body need to calcium. Consumption of two serves of pear during day can provide half of body need to sodium. Examined fruits cannot provide the daily body need to phosphorus, potassium and iron.
