“…Considering the changing living conditions and busy working schedules of the human, nowadays, processed foods including canned, packaged or frozen, have growing interest. These food types such as vegetables, fruits, meat and drink are highly consumed in daily life [1][2][3][4][5]. So, they are important sources of carbohydrates, proteins, fibres, vitamins, minerals and trace elements.…”

“…Consideringly, determination of the elements in the food samples is quite important to elicit the element profiles and amount that consumers are exposed to. Various techniques have been used for determination of the elements including flame atomic absorption spectrometry (FAAS) [11], graphite furnace atomic absorption spectrometry (GFAAS) [12], inductively coupled plasma optic emission spectrometry (ICP OES) [13] and mass spectrometry (ICP MS) [3,4] and polarography and voltammetry [14]. Among these techniques, ICP OES offers wide dynamic linear range.…”

In this work, determination of some elements including Pb, Ni, Ba, Fe, Zn, Mg, Mn, Al, Cu, Mo, Ca, B, Cr, Cd, V and Co were carried out in some canned and frozen vegetable samples sold in Balıkesir, Türkiye. The study covered randomly chosen 13 canned and frozen samples such as green peas, okra, shell bean, sweet corn, green beans, garniture and tomato paste. Mineralization of the samples was achieved using microwave assisted wet digestion in closed vessels. The element contents were determined using ICP OES. The element contents were between 0.16-1.86 mg kg-1 for Ni; 0.33-5.02 mg kg-1 for Ba; 4.20-32.22 mg kg-1 for Fe; 1.65-14.64 mg kg-1 for Zn; 124.83-1016.79 mg kg-1 for Mg; 0.87-4.99 mg kg-1 for Mn; 0.32-1.74 mg kg-1 for Al; 0.78-14.97 mg kg-1 for Cu; 0.38-4.24 mg kg-1 for Mo; 42.60-1607.40 mg kg-1 for Ca and 0.96-7.56 mg kg-1 for B. Additionally, Pb was determined in only frozen green peas as 1.3±0.1 mg kg-1. In general, the highest element contents were found in frozen samples. In terms of nutritional assessment, estimated daily intakes of the elements were compared with recommended dietary allowances (RDA), nutrition reference values (TFC) and daily tolerable upper intake levels (UL) which were established by World Health Organization, Turkish Food Codex and Institute of Medicine, respectively. The results showed that the element contents of the analysed samples did not exceeded the permissible limits set by various health organizations. It is concluded that the contamination of these products may be an important threatening for public health. Therefore, monitoring of these samples should be a vital strategy for food industry.

Coffee can be considered an important source of mineral nutrients. Since coffee is normally consumed through infusion, the availability of nutrients is related to the solubility, that is strongly influenced by the cultivation system applied to its production, which can influence the form of minerals are storage in the coffee bean. Coffee development is influenced by nutrient absorption, metabolism and storage. This study investigated the influence of cultivation on these characteristics of conventional and organic commercial coffee. The average concentration for conventional and organic cultivation determined in this study was 45.5 ± 11.2 and 64.7 ± 9.2 mg kg− 1 respectively. This result may be related to soil characteristics, such as acidic pH and reducing environment, favored by organic cultivation and favoring Mn solubilization in the soil solution, leading to greater Mn uptake. Principal component analysis shows differences between organic and conventional samples in the fractionation study. The characterizing fraction of the organic samples was the lipid and all other fractions characterized the conventional samples. This behavior suggests an influence of cultivation on Mn metabolism and storage by coffee. However, despite these observed differences, the average levels of Mn extracted from coffee infusions did not differ significantly between cultivation.
