In this work, the potential use of expanded polystyrene (EPS) in the Benitaka grapes packaging was investigated. First, the migration of residual styrene monomer, a determining factor for the regulation of plastic packaging in contact with food, was evaluated. The styrene migration tests, using distilled water as a simulant, shows a maximum of 1 μg / L of styrene migration (25 °C / 15 days), which is far below the maximum concentration allowed for plastic packaging, based on the World Health Organization (20 μg / L). In addition, the grapes stored in EPS packages were compared to cardboard packages under real post-harvest storage conditions. Two categories were evaluated: the grapes weight loss and the consumer buying decision (by applying a questionnaire to 384 consumers). After 15 days, the average weight loss of the Benitaka Grapes in EPS packaging was similar to the cardboard ones. Regarding the applied questionnaire to consumers, 60% of respondents tended to choose the EPS packaging. According to the survey, the decision making was mainly based on the product appearance. The rigid, modular, and palletizable characteristics of the EPS packaging provides better storage conditions, resulting in greater preservation of the final product aspect.
