SUGARCANE BAGASSE: ANALYSIS OF POLYPHENOLS, COMPOUNDS WITH ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES

Resumo

Sugarcane bagasse is a solid residue widely produced in Brazil and represents a great opportunity for exploration as source of functional compounds. Thus, the objective of the present work is to evaluate of total polyphenol, compounds with antioxidant and antibacterial activity. The results showed that aqueous extract from the sugarcane bagasse was not capable to inhibit the growth of important foodborne bacteria. Total polyphenolic content measured was 728,201±58,21 mg of gallic acid equivalent per 100g and flavonol content of 325,143±19,03 mg of rutin equivalent per 100 grams of dried bagasse. The antioxidant capacity was able to scavenge 5,05%±0,003% of DPPH radicals and presented ABTS scavenge capacity of 67,535± 10,44 mmol of trolox equivalent per 100 grams of dried bagasse. Thus, the present work may contribute to further studies to evaluate the residue to be used as functional component in industrial applications.
