This study aimed to quantify the levels of resveratrol, coumarin, and other bioactives in pulps and byproducts
of twelve tropical fruits from Brazil obtained during pulp production process. Pineapple, acerola,
monbin, cashew apple, guava, soursop, papaya, mango, passion fruit, surinam cherry, sapodilla, and tamarind
pulps were evaluated as well as their by-products (peel, pulp’s leftovers, and seed). Total phenolic,
anthocyanins, yellow flavonoids, b-carotene and lycopene levels were also determined. Resveratrol was
identified in guava and surinam cherry by-products and coumarin in passion fruit, guava and surinam
cherry by-products and mango pulp. These fruit pulp and by-products could be considered a new natural
source of both compounds. Overall, fruit by-products presented higher (P < 0.05) bioactive content than
their respective fruit pulps. This study provides novel information about tropical fruits and their by-products
bioactive composition, which is essential for the understanding of their nutraceutical potential and
future application in the food industry.
