NUNES, Ana Cláudia D. et al. Stored papaya ‘formosa’ coated with cassava starch base. Rev. de Ciências Agrárias [online]. 2017, vol.40, n.1, pp.254-263. ISSN 0871-018X.  https://doi.org/10.19084/RCA16048.

Among the technologies to reduce losses in post-harvest, the biofilm has function to coat the fruit prevented the gas exchange between the fruit and the environment. The cassava starch is a polysaccharide biofilm with the main benefits: increased efficiency and resistance and low cost. This study aimed to evaluate the effects of cassava starch, as biofilm, applied in papaya (Carica papaya L.) variety 'Formosa' Thainung1 obtained in the 2nd ripeness, comparing two concentrations, 2% and 4%, during 12 days, and stored at 10 ± 2 ° C. The statistical study was Entirely Randomized Design - DIC (3 x 5). Biofilm preserved the total soluble solids content, titratable acidity, promoted maturity index vitamin C, reduced mass loss, diameter, thickness and firmness of the fruit and the pulp. It is concluded that 2% of cassava starch biofilms increased the fruit shelf-life, and provided the highest quality.
