Determination of total phenolic content and antioxidant activity in pineapple fruit / Mohd Iszren Hairudin

This study was conducted to evaluate and compare the total phenolic content and antioxidant activity of selected local pineapple fruit (Ananas Comosus). Three types of local pineapple cultivar (Josapine, Morris and N36) were analyzed for total phenolic content (TPC) and DPPH (l,l-Diphenyl-2-picrylhy...
