SANTACRUZ TERAN, Stalin. Edible coatings based on cassava starch, salicylic acid and essential oils for preservation of fresh-cut mango. Rev. Fac. Nac. Agron. Medellín [online]. 2021, vol.74, n.1, pp.9461-9469. ISSN 0304-2847.  https://doi.org/10.15446/rfnam.v74n1.83837.

Mango has a short shelf-life after harvesting. The use of edible coatings on the elaboration of minimally processed mango is an alternative for its commercialization. In the present work edible coatings based on chitosan, starch-salicylic acid and starch-cinnamaldehyde-thymol were applied to fresh cut-mango. Weight loss, soluble solids, titratable acidity, color and microbiological analyses were studied along storage for 12 days at 8 °C and 90% relative humidity. Titratable acidity was the highest for mangoes coated with chitosan and the lowest was for starch-salicylic acid coating. Regarding instrumental texture, fruit coated with chitosan showed a higher penetration force compared to fruit coated with starch and uncoated samples. Microbiological results showed that all coated mangoes inhibited growing of fungi and yeast whereas uncoated samples showed an increase of both microorganisms along 12 days of storage period.
