Ferulic acid also known as hydroxycinnamic acid, is abundant in pineapple peel. It was identified and quantified by using both a UV spectrophotometer and HPLC. The antioxidant capacities of pineapple peel extracts and the total phenolic content were determined using DPPH scavenging capacity and Folin – Ciocalteu reagent Method. The alkaline hydrolysis of pineapple peel was optimized using Response Surface Methodology (RSM) via Central Composite Design (CCD) to enhance ferulic acid extraction. The parameters involved, namely temperature (°C) and duration of extraction (min.). The result obtained was 3.34 mgGAE/g for TPC and 46.34% DPPH. The extraction yield of ferulic acid was 0.471% using HPLC. The optimum conditions obtained from this study for temperature and extraction time are (42˚C, and 200 min), respectively
