METODE PENCUCIAN DAN PENYARINGAN PADA EKSTRAKSI PEKTIN DARI KULIT DURIAN
ABSTRACT: This research
was aimed to
know the washing
methods and filtration thickness
on the quality
of pectin extracted
from durian peel and
to increase economic
value on durian
peel waste. This
research was conducted
using a completely randomized design
with two factors,
namely the washing
methods; washed and
unwashed with alcohol
and filtration thickness: 1
piece, 2 pieces,
3 pieces, 4
pieces, 5 pieces, and 6 pieces.
The parameters analyzed
were yield, water content, ash
content, equivalent weight, methoxyl content, galacturonic content and
color. The results showed that the washing
methods had highly
significant effect on
yield, water content,
and colors and
had significant effect
on ash content and provided no
effect on equivalent weight, methoxyl content, galacturonic content. Filtration
thickness gave highly significant
effect on yield,
water content, ash
content, equivalent weight,
methoxyl content and
galacturonic content. Interactions
of the two factors gave highly significant effect on yield and color and had
significant effect on ash content and provided no effect on water content,
equivalent weight, methoxyl content and galacturonic content. Washing with
alcohol and filtration thickness of 6 pieces produce the best quality of durian
peel pectin.
