Voltammetry is an electrochemical technique widely used in quantitative analysis to determine nickel ions in food samples due to its excellent stability. Knowing the exact applied levels of metals such as nickel in different food samples is very important to prevent high nickel consumption, especially in people with allergies and nickel excess. Electrochemical analytical methods appear to be an alternative with many advantages, including high sensitivity, low detection limits on the g/L scale, ease of use, and sim...

Detection of nickel ions in various foods, especially fruits, is very important for the prophylaxis of patients with allergic contact dermatitis to this heavy metal. Currently, there are a limited number of rapid methods for identifying nickel ions, so it is necessary to develop new biosensors in this area, by improving selectivity of ligands and utilization of immobilization elements suitable for nickel ions. The mentioned elements are very important because they can increase the selectivity, sensitivity and can ...

Annually, worldwide the food industry generates huge quantities of plastic packaging (polyethylene, polypropylene, polystyrene, polyethylene terephthalate, etc.) and due to their chemical structure takes hundreds of years to degrade, thus creating major environmental problems. Therefore, the aim of this study was to develop biodegradable films that can be used for food packaging and to identify their physical and mechanical properties. The biodegradable films were obtained using 150 ml Milli-Q water and different ...
