“…The fruit cultivar, agricultural practice, and processing may be crucial factors determining the elemental composition of the juice, so that pre-and post-harvest factors determine the expected elemental concentration of fruit juices (Cisse et al 2005;Nienaber & Shellhammer 2005;Léchaudel & Joas 2007;Jalbani et al, 2010;Fernandes, et al 2011;Bragança et al 2012).…”

Pre-and post-harvest factors determine the levels of the selected risk elements in100% fruit juices. The juices samples closely followed the Brix international reference values. Fruit juices presented the following order of the elements mean concentrations: cadmium (1.597 μg/l), chromium (2.767 μg/l), lead (20.75 μg/l), nickel (73.37 μg/l), zinc (545.9 μg/l), and iron (1792 μg/l), measured by AAS. The pre-harvest factors (origin, fruit, and agriculture) and the post-harvest factors (blending, packaging, conservation, pasteurisation, and process) were evaluated according to the manufacturers information and were correlated with the elements concentrations of fruit juices. A strong relationship was detected between the fruit species used for the juice production (i.e. pre-harvest factor) and their elements concentrations. Furthermore, multiple correspondence analysis was used for reducing the data dimension by grouping the factors. The zinc concentration was detected as a potential proxy for the identification of the fruit juices manufacturing process.

“…The analysis of individual components of raw and processed products is necessary in the food industry mainly to control the food safety (Sádecká & Polonský 1999). At present, essential and toxic metals in food and beverages are qualitatively and quantitatively studied by using mainly atomic absorption spectrometry (AAS) (dos Santos et al 2009;Jalbani et al 2010;Kazi et al 2010), inductively coupled plasma mass spectrometry (ICP-MS) (Roychowdhury et al 2003;Nardi et al 2009;Kaňa 2010) and inductively coupled plasma optical emission spectrometry (Lara et al 2005;Oleszczuk et al 2007;Santos et al 2008). Other techniques include X-ray fluorescence spectrometry (Jastrzebska et al 2003), electromigration techniques (Sadecka & Polonsky 1999;Szlyk et al 2004), and some electrochemical techniques (Karadjova et al 2000;Abbasi et al 2010;Alghamdi 2010).…”

We determined the mineral nutrients and toxic elements (Ca, Cu, Fe, Mg, Zn, Cd, Cr, Mn, Ni, and Pb) in five types of coffee by atomic absorption spectrometry and inductively coupled plasma mass spectrometry. The decomposition of the samples took place in a microwave digestion system with HNO 3 and H 2 O 2 reagents. Partial validation of the method was performed by using the certified reference material (NCS ZC 73014). Univariate and multivariate statistical methods were used to compare both the coffee samples and the techniques used. No significant differences were found between two used methods. Significant differences occurred between the coffee samples but only the application of multivariate statistics helps to distinguish among samples from different locations.

“…A more vibrant range of zinc (0.05 -0.23mg/L) in fresh juices from tropical climate of Brazil (Braganca, Melnikov, & Zanoni, 2012) and commercially available orange juice from Turkey (0.234 -0.471 mg/L) has been reported in literature (Harmankaya, Gezgin, & Ozcan, 2012). A comprehensive study on copper, iron and zinc contents of commercially available fruit juices of Pakistan had reported mango and orange juices to carry 0.296 and 0.315 mg/L respectively (Jalbani et al, 2010) as shown in Table 4 3.3.

Street vended juices are most commonly available, accessible and economical nutritional food sources of poor slums in developing economies like Pakistan. Study was undertaken to elucidate impact of industrialization, agro chemicals induction in agronomic practices and food processing hygiene measurements on food chain heavy metals intoxication. If overlooked, certain quality risks associated either with fresh produce or processed commodity might initiate food intoxication.In order to understand gravity of the issue, street vended freshly drawn juices extracted from the food crops (orange, sugarcane, carrot and mango) cultivated in Southern Punjab peri-urban areas and country sides were evaluated for microelements and heavy metals load in summer and winter 2012. The safety study of juices depicted higher concentration of lead (Pb) and cadmium (Cd) breaching international safety limits implemented in the country. However some microelements (Fe, Zn, Mn) were found below the prescribed maximum tolerant limits. The study concluded prevalence of higher concentration of some toxic heavy metals as a serious breach of threshold levels potentially compromising consumer's safety.
