Resumen:
Due to increasing demand for organic products, new forms of conservation, such as the use of edible coatings have been studied as an option is to keep the quality ofthe food. In this regard aimed to evaluate the effect of microalgae-based biofllm (C#/ore//a sp.) under different concentrations and kinds of applications on the post-harvest conservation of Guava (Ps/dfum gua#at'a L., cv Paluma) stored under ambient conditions. This study was conducted in a completely randomized design with 2 x 3 factorial, two difTerent application methods, sprinkling and immersion, and three biofilm concentrations (0%, 1%, 2%), with 12 repetitions. The use of C#/ore//a sp. biofilm under the concentration of 2% promoted
maíntenance oftotal sugars and carotenoids during the maturation of guava fruit. For the bolos parameter, the concentration of 2% of the bioHilm was efTicient on the lightness (L'k) of the fruit, which obtained low values, and on the delay of bolor development, under the values expressed by C+, h*, a+. The biofilm did aRect pH and soluble solids (SS).
