“…Even though, a limited number of samples were investigated in the scope of our study, our findings prevail over the improvement of the ceramic industry in Turkey in terms of application of proper glazing processing as reported by Çiftçi and Henden (2016). Our results are the indication of the application of good manufacturing conditions and undamaged glaze on the surface (Dong et al, 2015;González-Soto et al, 2000;Türközü & Şanlier, 2014). Moreover, our findings are below the permissible limit set for the lead as 4 mg/L and for cadmium as 0.3 mg/L (European Commission, 1984).…”

The aims of this study were (i) to evaluate the existing analysis capacity for lead and cadmium leached from ceramic articles, (ii) to determine the migration of lead and cadmium from glazed ceramic kitchenware sold on the Turkish market, (iii) to estimate the sampling uncertainty. Traditional ceramic cooking ware and Chinese breakfast hollowware were sampled randomly from different sales points located in Bursa in 2018 (n = 96). Ceramic articles were subjected to the migration conditions specified in the legislation, and the amount of lead and cadmium was determined with the inductively coupled plasma and mass spectrometry. It was found that the current analytical method can quantify lower levels of the metals with acceptable method performance parameters. The amount of the metals migrated were far below the current permissible limits set in the legislation. Relative sampling uncertainty was estimated as 66.1% and this result was related to the heterogeneity within a lot.

“…Therefore, the release amount M t at time t should be corrected to ensure the accuracy of the D value. Equation could be used to correct M t.

M_{t} = V_{f} C_{t} + V_{q} \sum_{i = 1}^{t - 1} C_{i}

High density polyethylene/low density polyethylene (LDPE) antioxidant multilayer films were prepared by the co‐extrusion method, and quercetin was incorporated in the LDPE layers as an antioxidant. The release rates of quercetin and the antioxidant activities of films were adjusted by changing the amount of ethylene vinyl acetate (EVA) and diatomite added into the LDPE active layer. The morphologies of the films were observed by SEM, and the release property of quercetin was characterized by a high‐performance liquid chromatography (HPLC) method. The mechanical properties and heat sealing performance of the films were influenced to a certain extent by the amounts of EVA and diatomite in the active layers, while the barrier properties of the films were almost unchanged. The release of quercetin from the active films to a food simulant (95% alcohol) at 37°C was measured over 55 days. When the EVA amounts were 30% and 40% to 50%, the diffusion coefficients, D, were 10−14 and 10−13 cm2/s, respectively. In addition, the antioxidant activity values of the films were enhanced as the EVA amount increased. When adding diatomite into the active layer with 50% EVA, the diffusion coefficient, D, was 10−11 cm2/s, and the quercetin was almost completely released with a partition coefficient, K, of less than 1. Meanwhile, the antioxidant activity values of the films exceeded 95%. The antioxidant release rate could be adjusted within a wide range; thus, these active films could be used for food antioxidant protection.

“…Stochastic thermodynamics models measure the thermodynamic changes due to food packaging interaction such as temperature, pressure and moisture changes while molecular models of a stochastic methods measure the rate of molecular changes/interaction of gaseous or chemical molecules arises due to disintegration of either packaging or food components and subsequent molecular interaction [8,54]. Stochastic models such as Life Cycle Assessment (CA) and High-Throughput Risk-based Screening (HTRS) tools are used to determine extent of migration in plastic packaging while empirical Weibull Model has been used to determine the chemical migration curves in paper packaging [55], Mechanistic Models are used to predict the migration of toxic metals into acidic food [56] while diffusion models are used for the determination of migration in ceramic packaging as well as packaging with low migration risk or plastic additives with low diffusion potentials. Predictive models are used to generate data and also been associated with statistic functions to develop software programs that simplify the determination methods for food-packaging interaction.…”

The most important role of food packaging is to provide a total barrier to physical, biological and/or chemical factors that can tender the quality integrity of the packaged food, an ideal food packaging should be rigid and non-reactive to the food enclosed. That is, a packaging material should be safe by and/or for the food. Food and packaging may interact and pose effects, which may affect the quality, integrity and shelf life of the food. This chapter discusses the processes of food packaging interaction such as permeation, migration, sorption and their adverse effects on the food packaging system. Novel packaging systems such as Active packaging (packaging that preserve, communicate and protect quality integrity of the food), Intelligent packaging (packages with improved communication models that help consumers ascertain the quality and the state of the food) and Bio-active packaging (are active packaging with improve compound in them that support stability of the food) were discussed as advanced packaging systems that help in mitigating the food-package interaction as well as give consumer conveniences while extending shelf stability. Scientific models used in studying the extent of food packaging interaction are also discussed which includes the stochastic, mathematical and simulation models.
