PP eco-friendly Extraction of Banana Agro-industry Waste and its Functional Groups
MetadataShow full item record
Pectin or pectic polysaccharides is a naturally-occurring polysacharride found in many plants. Its effects on health is receiving growing interest for their applications such as prebiotic ingredient. In this work, pectin was isolated from banana agro-industry waste (peel and bunches of bananas) by using water extraction method. There were three methods i.e. one time, two times and three times of extraction. The extracted pectin was characterized by FTIR. The result showed that pectin extraction method was twice (two times phase of extraction) as much as the extraction stage effective and efficient to extract the pectin than one or three times extraction. The results of functional groups analysis was using FTIR instrument indicated that the peak of extracted pectin had the same functional group with standard pectin. But there were impurities (ethanol compound) as a effect of the analysis performed on wet samples (pectin has not dried). Functional groups presented in the pectin from banana waste i.e intermolecular alcohol group, a carboxylic acid dimer, free carbonyl, amine compounds and group of primary and secondary aliphatic.
