Abstract: The study aims to develop an edible coating to extend the shelf life of pineapples using cassava starch. The increasing popularity of minimally processed fruits has led to a search for sustainable alternatives to traditional plastic films used in the food industry. Edible coatings are a promising technique to reduce moisture loss and deterioration of fruits. The experiment was conducted at the physicochemical analysis laboratory of UFRPE in Recife, using ripe pineapples treated with cassava starch solutions at concentrations of 1%, 2%, and 3%. The fruits were analyzed for mass loss, texture, water activity, pH, acidity, and total solids over 6 days. The results showed that pineapples treated with cassava starch had a higher mass loss compared to the control group, possibly due to the syneresis of the gelled starch. The texture of the samples did not show significant differences from the control, despite some initial variations. Water activity increased in all samples, indicating a possible fermentative process. pH and total acidity varied, with 1% and 3% starch samples showing greater stability. However, acidity was higher in the treated samples compared to the control. The total solids analysis revealed similar results across all groups by the end of the experiment. In summary, cassava starch coatings, regardless of concentration, were not effective in significantly increasing the shelf life of sliced pineapples.
