“…Considering the analyzed sample types as frozen and canned, the levels of Mn did not show a clear trend to differentiate. The results were in good agreement with [8] and [21]. On the other hand, previous finding from Türkiye [1] is about five times that observed for the counterpart assortments in this study.…”

“…Generally, it may be concluded here that Fe levels of canned food samples were lower than the frozen food samples for investigated samples. Comparing the data, the results were found almost similar to that found in Lebanon [7], India [8], Iran [11] and Ghana [21] for various canned or frozen food samples, but lower than the data obtained by Tuzen and Soylak [1].…”

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.

“…Heavy metals can be taken into the living organism by ingestion, inhalation, and dermal absorption, which then might cause toxicity when exceeding the recommended limit. However, food and water are the primary sources of heavy metals exposure to the human body [81,82]. Heavy metals in the environment (soil and water) have increased significantly as a result of biomagnification and accumulation into foods as a result of anthropogenic, geological, and industrial activities.…”

Food contains a variety of poisonous and harmful substances that have an impact on human health. Therefore, food safety is a worldwide public concern. Food detection approaches must ensure the safety of food at every step of the food supply chain by monitoring and evaluating all hazards from every single step of food production. Therefore, early detection and determination of trace-level contaminants in food are one of the most crucial measures for ensuring food safety and safeguarding consumers’ health. In recent years, various methods have been introduced for food safety analysis, including classical methods and biomolecules-based sensing methods. However, most of these methods are laboratory-dependent, time-consuming, costly, and require well-trained technicians. To overcome such problems, developing rapid, simple, accurate, low-cost, and portable food sensing techniques is essential. Metal-organic frameworks (MOFs), a type of porous materials that present high porosity, abundant functional groups, and tunable physical and chemical properties, demonstrates promise in large-number applications. In this regard, MOF-based sensing techniques provide a novel approach in rapid and efficient sensing of pathogenic bacteria, heavy metals, food illegal additives, toxins, persistent organic pollutants (POPs), veterinary drugs, and pesticide residues. This review focused on the rapid screening of MOF-based sensors for food safety analysis. Challenges and future perspectives of MOF-based sensors were discussed. MOF-based sensing techniques would be useful tools for food safety evaluation owing to their portability, affordability, reliability, sensibility, and stability. The present review focused on research published up to 7 years ago. We believe that this work will help readers understand the effects of food hazard exposure, the effects on humans, and the use of MOFs in the detection and sensing of food hazards.

“…Heavy metals may be present in canned tomato paste through uptake by plants from contaminated soil, polluted water and from applied agrochemicals. The harvested fruits may become contaminated during canning processes due to leaching from the metal containers into the canned product during storage (Nincevic et al 2009, Nathaniel et al 2012. Toxic heavy metals such as Pb, Co, and Cd can be differentiated from other pollutants since they are not biodegradable.…”

In recent years there has been an increase in the contaminations of heavy metals on the environment. Government and private organization have shown their interest in the effect of dietary exposure to several heavy metals. These heavy metals have been implicated in the etiology of many diseases with high risk to humans. Canned tomatoes paste is one of the important health deterioting factors to human health in Ubani-Umuahia, Nigeria. In this study atomic absorption spectrophotometer was used to screen for nine heavy metals concentration in ten different brands of canned tomatoes paste sold at Ubani-Umuahia market in Nigeria. Human risk assessment was calculated using the collated data to evaluate the predictive risk of human health after the consumption of canned tomatoes paste. Results shows that lead and nickel were not detected in all the canned tomatoes. In comparison low concentrations of copper, iron, and manganese were notated but high concentrations of chromium and cadmium were detected in all the tested tomatoes pastes. Cobalt and zinc concentration was notated lower than permissible limit. The daily intake of copper, cobalt, manganese, chromium, cadmium, nickel, iron, zinc and lead were below their tolerable values in canned tomatoes. The predicted lifetime for carcinogens to occur was less than one (<1). Copper, cobalt, iron, and zinc were below the acceptable value for non-cancer risk with HQ <1.The risk of incurring cancer by ingesting canned tomatoes was within the lifetime predicted a range of (1.0E-6 to 1.0E-4). Finds suggest that prolong and persistent consumption of these heavy metals may cause toxicity and consequential heath challenges. J. bio-sci. 28: 1-11, 2020
