Food packaging’s materials: A food safety perspective

24/4/2021 · In the former case, the molecularly diffused low-molecular weight substances such as additives and oligomers from the packaging films are transferred into the foods (Helmroth et al., 2020). In the latter scenario, the mass transfer of food color, aroma, flavor, and nutrients happens from the food product to the packaging and results in a strong impact on the organoleptic properties of foods Glycerol as an Efficient Plasticizer to Increase the DC 14/2/2022 · The high absorption between 3000 and 3800 cm-1 is thought to be due to hydroxyl stretching vibration. C–H rocking in PVA has been allocated to the peak at the 850 cm-1 ().In doped PE solutions, this peak is displaced. The bands at 1094 cm-1 and 1320 cm-1 relate to the pure PVA's –C–O– stretching and C–H deformation, respectively (Rajendran et al., 2004).
