Pengaruh Suhu Ekstraksi Terhadap Rendement Dan Kadar Metoksil Pektin Dari Eceng Gondo (Eichornia crassipes (Mart Solms)
ABSTRACT: The purpose of this
research is to find out the influence of the extraction temperature on the
rendement and pectin methoxyl contents of waterhyacinth with the applied
temperatures ranged from 60, 70, 80, 90 and 100 °C.The stages of this research
involve extraction, precipitation, washing and drying. The pectin produced was,
then, identified by reacting it with water, ethanol 96 %, NaOH and
spectrophotometer IR. Its product was, then, compared to the comparing pectin.
To determine the methoxyl contents, the acid - base titration was used. The
resulting data were analysed and tested using One Direction Anava with SPSS
10.0 program. From the quantitative used by this study, pectin was produced.
This is shown by the gel-formation. The rendements produced with the extraction
temperatures of 60, 70, 80, 90 and 100 °C were 0,428 %; 0,487 %; 0,629 %; 0,774
% and 0,958% respectively. While its methoxyl contents were 3,879 %; 3,993 %;
4,413 %; 3,573 % and 2,837 %. Based on the analysed data, it was found that the
treatment with the extraction temperature gives a significant influence on the
rendement and pectin methoxyl contents of waterhyacinth.
