| dc.description.abstract | 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. | en_US |
