Current development using the technique of Rapid Expansion Supercritical Solution (RESS) in solid oil particle formation pineapple peel contains a great deal active pharmacological which are anti-inflammatory, anti-oxidants, and anti-cancer agent. Many researchers use the conventional technique such as hydro-distillation, supercritical fluid extraction, and soxhlet extraction in order to extract the valuable component in oil formed. However, these techniques have several disadvantages such as long extraction time, high usage of solvent and produce toxic residual which can harm the environment. The RESS technique is not as time consuming as it will directly produce oil in particle formation, instead of conventional technique that need to undergo further technique such as spray drying in order to produce solid oil particle. In this study the extraction was conducted using temperature 40, 45, 50, 55, 60°C and the pressure used were 3000, 4000, 5000, 6000 and 7000 psi at a constant flowrate of 24ml/min for 50 minutes extraction time. The extracted component in solid oil particle was analyzed using Gas Chromatography Mass Spectrometry (GCMS) and show that pineapple peels is rich in volatile components such as 1-Hexene, 4-methyl, Benzene, 1,1’-(1,2 cyclobutanediyl) bis-, trans, and 1-Buten-3-one, 1-(2-carboxy-4,4-dimethylcyclobutenyl).
