“…However, in several previous studies, higher levels of lead were found in fruit and fruity vegetable samples produced or sold in Saudi markets (Aldjain et al 2010;Ali & Al-Qahtani 2012;KAIRCS 2004;Mohamed et al 2003).…”

The levels of four metals (Zn, Cu, Cd, and Pb) were evaluated in two fruit types (apricot and fig), a fruity vegetable (tomato), and three leafy vegetables (arugula, spinach, and lettuce) that are commonly grown and consumed in Aseer Region, Saudi Arabia. Flame atomic absorption spectrophotometry was employed for quantification. The quality of results was checked by a certified reference material (NIST SRM 1570a). Good recovery values in the range of 87-104% were achieved. Metals were quantified in washed and unwashed samples to evaluate the effect of washing. Statistically, no significant difference was noticed (p>0.05), except for Zn in arugula and Cu in apricot and spinach. The levels of metals found in the analyzed fruits and vegetables were in their normal ranges in crops and not posing any serious risks to the consumers in Aseer Region. The toxic elements Pb and Cd were well below the maximum levels set in the Saudi and international food standards. Zn and Cu levels were comparable to the ranges reported in worldwide previous studies.

“…Aldjain et al [21] determined the concentration of lead (Pb) and cadmium (Cd) in washing residues and in the tissues of fruits of date palm growing in 14 sites of Riyadh. They stated that humans are likely to be exposed to heavy metal contamination from the dust that adheres to edible plants than from bioaccumulation.…”

The aim of this study was to determine the chemical composition, minerals and antioxidants of heart of date palm from three Saudi cultivars. Moisture (ranged from 80.44% -82.82%) was the predominant component in the heart date palm. Sukkari cultivar had the highest protein (5.27%) and ash (7.9%) compared to the other two cultivars. Fat was low in the three cultivars. Sucrose was the predominant sugar in the heart date palm and ranged from 7.65% -20.25%. Potassium was the predominant mineral in the heart date palm and was significantly (p ˂ 0.05) higher in Sukkari and Solleg compared to the Naboat Saif cultivar. Sulfur and chloride were next to potassium in abundance in the three heart date palm cultivars. Total phenols and flavonoids were higher in Solleg compared to the other two cultivars. IC50 for Solleg, Sukkari and Naboat Saif were 0.12, 0.13 and 0.29 mg/ml, respectively. The results of the present study may highlight the potential importance of heart of date palm as a product rich in essential minerals and antioxidants. Future researches are needed to explore other characteristics of heart of date palm which could be considered for human nutrition.

“…A very important step is the washing of samples after collection. The use of tap water (Al Hooti et al 1997) or double-distilled water (Sulieman et al 2012;Aldjain et al 2011;Taha and Ghtani 2015) instead of deionized water results in a relatively high level of the blank sample, which may make it impossible to detect trace elements. The drying stage is also very important.…”

“…Consumption of 100 g of dates provides 15% of the daily demand for selenium, copper, potassium and magnesium (Al-Showiman 1998). Many researchers focused in their experiments on determining the elemental composition of dates from various regions: Spain (Abdrabo et al 2015), Oman (Al Farsi and Lee 2008), Saudi Arabia (Aldjain et al 2011;Assirey 2015;Hamad et al 2015;Mohamed 2000), Sudan (Mohamed et al 2014;Sulieman et al 2012). The scientists focused on determination elements that are essential for human organism as well as toxic.…”

Determination of the elemental composition and antioxidant properties of dates (Phoenix dactyliferia) originated from different regions

Due to the growing interest in running a healthy life, including the diet a special interest has been put in searching for products that are rich in nutrients, macro and micronutrients and vitamins. Dates are the fruits that meet these requirements and show multidirectional pro-health effects. These fruits are a source of potassium and other macro-and micronutrients. They have antioxidant properties thanks to the content of flavonoids and polyphenols. The elemental composition (Al, Ca, Cu, Fe, K, Mg, Mn, P, Sr and Zn) and antioxidant properties (total equivalent antioxidant capacity, total polyphenol content, total flavonoid content) of various dates from different regions of the world was determined. The results have shown that the peel and flesh of dates differ significantly in chemical composition. The peel is significantly richer in chemical components of biological importance. Discriminant analysis of the results obtained for dates originated from various regions indicated that the main factor determining the tested chemical composition is the place of cultivation, not the variety.
