Food Simulant

Varnishes used as the inner coatings of food cans are often based on epoxy resins or vinylic organosols. The epoxy resins can be produced from bisphenol A (BPA) and bisphenol F (BPF) and they also contain bisphenol A diglycidyl ether (BADGE) of bisphenol F diglycidyl ether (BFDGE) as stabilising components. These compounds may break down during storage and also by influence of food simulants. The stability of BADGE and BFDGE was studied using reverse-phase gradient high performance liquid chromatography (RP-HPLC) with fluorescence detection (FLD). Four experiments were compared: (i) BPA solution at the concentration 3 μg/ml of each food simulant, (ii) BADGE solution at the concentration 3 μg/ml of each food simulant, (iii) BFDGE solution at the concentration 3 μg/ml of each food simulant and (iv) mixture of all bisphenols solution at the concentration 3 μg/ml of each food simulant. Distilled water, 10% ethanol, 95% ethanol and 3% acetic acid were used as food simulants. It was observed that BPA, BADGE and BFDGE were most stabile in 95% ethanol and least stabile in 3% acetic acid. Creation of hydroxy and chlorohydroxy derivatives was in each food simulant different so it cannot be predicted.

The high-pressure crystallized poly (ethylene terephthalate) / bisphenol-A polycarbonate (PET/BAPC) blend samples were investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Besides the extended-chain single crystals with high quality and large c-axis thickness, the results showed that some novel crystal morphologies were formed in the multi-phase system within a relative short time. Spherulitic structures with different characteristics were observed, in and out the cultured polyester extended-chain crystals, respectively, and their substructures were found to be extended-chain lamellae. Furthermore, bud-like nano-crystals with zero- or one-dimensional structures, some of which aggregated and then evolved into three-dimensional nano-dendrites, were grown during the cooling process of the polyester blends at high pressure. The disclosed entities during this study may promote the understanding of formation process and mechanism for both spherulite and extended-chain crystals of polyesters, so as to instruct the processing of such alloyed engineering plastics with high performance.
