Greater access to processed foods worldwide poses challenges for regulatory bodies while feeding debates about the effect of such foods on human health. In contrast to their raw material ingredients, processed food matrices possess vastly more complex biochemical profiles. In this work, we demonstrate the ability of hydrolytic enzymes to facilitate the enhanced release of metals from three different processed food matrices. Our approach relies on the ability of the hydrolytic enzymes to cut or loosen biopolymeric components present in the processed food items, followed by the mass spectrometric detection of released metals. A combination of cellulase, pectinase, xylanase, and amylase disrupted the surface and overall architecture of the processed food items as indicated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Hydrolytic enzyme treatment resulted in the measurement of significantly higher levels of Cu, Mn, Zn, Cr, and As and between 20 and 250% higher levels of Pb and Sn across all three food matrices. We used RSM and ANOVA to optimize the conditions underlying hydrolytic enzyme treatment, for example, for Pb as pH 7, incubation time of 30−48 h, and enzyme concentration of 50 mg/mL. We analyzed the food product packaging materials as a prospective source of lead and tin and observed commensurate levels in the packaging to those measured after hydrolytic enzyme treatment of the contained foods. Treatment of the processed foods with immobilized hydrolytic enzymes results in a similar profile of the elements as obtained with the use of soluble enzymes, thereby promising the adaptability of our method to a reusable format. The approach presented in this work lays the groundwork for an important sample treatment strategy for the superior chemical analysis of processed foods.

“…On the other hand, a single analysis cannot guarantee the determination of NP migration in all foods and food simulants, at all temperatures, and therefore it is important to utilize several tests to obtain accurate results. Table 1 shows a brief report of the test methods used to study different aspects of nanobased systems, including food packaging (as discussed by dos Santos [69]). These methods also provide sufficient information about the composition, concentration, and physicochemical properties of the nanomaterials in the sample; however, it is not possible to determine the true amount of NPs in the food texture.…”

Packaging containing nanoparticles (NPs) can increase the shelf life of products, but the presence of NPs may hazards human life. In this regard, there are reports regarding the side effect and cytotoxicity of nanoparticles. The main aim of this research was to study the migration of silver and copper nanoparticles from the packaging to the food matrix as well as the assessment techniques. The diffusion and migration of nanoparticles can be analyzed by analytical techniques including atomic absorption, inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission, and inductively coupled plasma optical emission spectroscopy, as well as X-ray diffraction, spectroscopy, migration, and titration. Inductively coupled plasma-based techniques demonstrated the best results. Reports indicated that studies on the migration of Ag/Cu nanoparticles do not agree with each other, but almost all studies agree that the migration of these nanoparticles is higher in acidic environments. There are widespread ambiguities about the mechanism of nanoparticle toxicity, so understanding these nanoparticles and their toxic effects are essential. Nanomaterials that enter the body in a variety of ways can be distributed throughout the body and damage human cells by altering mitochondrial function, producing reactive oxygen, and increasing membrane permeability, leading to toxic effects and chronic disease. Therefore, more research needs to be done on the development of food packaging coatings with consideration given to the main parameters affecting nanoparticles migration.

“…Due to its favourable toughness and ductility [ 1 , 2 , 3 ], cadmium (Cd) is becoming one of the most frequently used elements in the manufacturing of metal, plastic and dyestuff materials, which are commonly used in food packaging, kitchenware, plastics, bottles and boxes [ 4 , 5 ]. Increased public awareness of contamination in food packaging materials has raised global concerns regarding potential heavy metal environmental contamination from packaging [ 6 , 7 ].…”

Heavy metals in food packaging materials have been indicated to release into the environment at slow rates. Heavy metal contamination, especially that of cadmium (Cd), is widely acknowledged as a global environment threat that leads to continuous growing pollution levels in the environment. Traditionally, the detection of the concentration of Cd relies on expensive precision instruments, such as inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES). In this study, an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) based on a specific monoclonal antibody was proposed to rapidly detect Cd. The half-inhibitory concentration and detection sensitivity of the anti-cadmium monoclonal antibody of the ic-ELISA were 5.53 ng mL−1 and 0.35 ng mL−1, respectively. The anti-Cd monoclonal antibody possessed high specificity while diagnosising other heavy metal ions, including Al (III), Ca (II), Cu (II), Fe (III), Hg (II), Mg (II), Mn (II), Pb (II), Zn (II), Cr (III) and Ni (II). The average recovery rates of Cd ranged from 89.03–95.81% in the spiked samples of packing materials, with intra- and inter-board variation coefficients of 7.20% and 6.74%, respectively. The ic-ELISA for Cd detection was applied on 72 food packaging samples that consisted of three material categories—ceramic, glass and paper. Comparison of the detection results with ICP-AES verified the accuracy of the ic-ELISA. The correlation coefficient between the ic-ELISA and the ICP-AES methods was 0.9634, demonstrating that the proposed ic-ELISA approach could be a useful and effective tool for the rapid detection of Cd in food packaging materials.
