In this paper, five different case studies were carried out to analyze and examine the presence and prevalence of food safety related disease, the economy and the political situation of fourteen different developing countries. The studies' goal was to determine if there is a correlation or connection between the country's level of democracy and the food-related health issues. The research method included an extensive gathering and analysis through descriptive statistics of the documentation and data provided from Non-Governmental Organizations and health organizations. Articles, academical analyses and third party on-the-ground reports were used too. For the political section, the attention has been focused on the institutional democracy (structural level) and on the civil rights and personal freedoms (social level). For the health-issues part, it was decided to focus on the most relevant indexes of food safety status among the population: diarrheal diseases, intestinal infectious diseases, liver cancer and malnutrition. This research denotes that there is a connection between the level of democracy and food-related health issues. As the democracy level increases, the prevalence of the aforementioned diseases decreases, but it also highlights that other economic factors could play a crucial role too. Lastly, it also suggests that democracy alone cannot address some health issues (such as malnutrition) and other ways need to be found.

The thermal stability of four different commercial citrus peel extracts was tested and improved by an encapsulation process with β-cyclodextrins in a spray-dryer. All extracts after the encapsulation process maintained a good antioxidant capacity, with an apparent loss in total phenolic compounds of around 20–25%. In addition, all samples showed good antimicrobial activity (MIC 5–0.625 mg/mL) against Staphylococcus aureus, which was maintained after the encapsulation process (MIC 5–1.25 mg/mL). Based on the antioxidant and antimicrobial activity results, the best-encapsulated citrus extract was selected for incorporation into a polylactic acid/polyhydroxy butyrate (PLA/PHB) film. The latter was then produced on an industrial scale by cast extrusion and was found to be suitable for food contact as it showed overall migration values in different food simulants lower than the legislative limit of 10 mg of non-volatile substances per 1 dm(2) of surface area. The UHPLC-HRMS analysis, performed to evaluate the migration of the active compounds, revealed about 13.41% release in food simulant A and 11.02% in food simulant B. Antimicrobial analysis conducted directly on the film showed a growth inhibition activity towards Escherichia coli and Staphylococcus aureus equal to 30 and 60%, respectively.
