Microwave assisted extraction of phenolic compound from pineapple (Ananas comosus) peel and core: article

Nowadays, microwave-assisted extraction has caught tremendous interest by researcher for extracting bioactive compound. The reason MAE being so popular are because extraction by using MAE can enhance extraction yield and it is also cost efficient because it can reduce extraction time and usage of extraction solvent compared to traditional extraction process. This experiment was used to study the effect of irradiation power on pineapple peel and core, and to obtain the best solvent for extract phenolic compound. Phenolic compound from a fruit has being proved for the effective management of such chronic disease because in phenolic compound it contain positive intervention in the pathological pathway. The parameters used are different type of solvents and different microwave power (100W, 300W and 600W). The method use for the extraction is by microwave assisted by using ethanol and distilled water as a solvent for 5 minutes exposure time. Then total phenolic compound analysis is being made by using Folin-Ciocalteu spectrophotometric method. After the reaction with saturated sodium carbonate, the extraction sample was measure 765nm by using UVspectrophotometer for 30 minutes. The determination by the Folin-Ciocalteu reagent using gallic acid solution as a calibration curve. Furthermore, it can be conclude that distilled water is more efficient if used at higher temperature but the extraction yield is quite low and ethanol is more efficient if used at low microwave power because at low power it already enough to break the cell wall without having any bioactive compound degradation.
