Sugar solubility in water, alkali or acid solvent and polysaccharide chemical
component of fibrous feeds treated with urea were investigated in the research.
Materials used were banana peel, pineapple by-product, cocoa pod and sugarcane
bagasse. All of them were amoniated with 0%, 1.5% and 3% urea. Ten gram
ammoniated products were then crushed for 50 minutes with 150 gram glass crumble
under water, alkali or acid condition. Extraction product were sentrifuged and supematan
containing polysaccharide were taken and then dialysis. Completely Randomized Design
with 3 urea treatment (0%, 1.5% and 3%) was used. Data analysis used ANOVA and
when ANOVA show some difference, Duncan's range test was used. Parameter
meassured were sugar solubility of the polysaccharide before dialysis (SS bD) in water,
alkali or acid condition, sugar solubility of the polysaccharide after dialysis (SS aD) in
water, alkali or acid condition, oligosaccharide solubility, percentage of increase sugar
solubility in water condition compared to alkali and acid condition and polysaccharide
chemical component of banana peel and cocoa pod.
Compared with the other materials, cocoa pod showed highest polysaccharide
solubility in water, whereas highest oligosaccharide solubility in water was found in
pineapple by-product. Highest polysaccharide and oligosaccharide solubility in alkali
were, respectively, banana peel and pineapple by-product. Polysaccharide and
oligosaccharide of sugarcane bagasse were highly in acid. Urea treatment showed no
significant effect on sugar solubility of sugarcane bagasse, pineapple by-product and
cocoa pod dissolved in water. However banana peel treated with 1.5% urea indicated
significantly higher (P0.05) terhadap total gula yang larut dalam air, kecuali
perlakuan urea pada kulit pisang. Kulit pisang yang mendapat perlakuan amoniasi
1.5% urea nyata (R0.05) lebih tinggi dari kulit pisang yang mendapat perlakuan
amoniasi 0% dan 3% urea. Persentase peningkatan polisakarida dan oligosakarida
terlarut tertinggi dari pelarut air ke basa b e r t ~ ~ t - t u r uadalah
t
kulit pisang dan
baggase, sedangkan peningkatan polisakarida dan oligosakarida tertinggi dari air ke
asam adalah bagasse tebu. Kulit pisang dan kulit coklat mengandung glukosa dan
fruktosa sebagai komponen penyusun polisakaridanya. Glucoronic acid dan
glucosamine tidak terdeteksi ada pada komponen kimia polisakarida kulit pisang dan
kulit coklat.
Berdasarkan penelitian tersebut dapat disimpulkan bahwa kulit coklat dalam
pelarut air mempunyai kelarutan polisakarida tertinggi dibandingkan bagasse tebu,
limbah nenas dan kulit pisang. Perlakuan urea tidak cukup efektif untuk
meningkatkan kelarutan @la polisakarida dan oligosakarida dalam pelarut air, basa
dan asam pada kulit coklat,. bagasse tebu dan limbah nenas. Kom~onenkimia
polisakarida k ~ l i t - ~ i s a ndan
g kulit coklat adalah glukosa dan fruktos;, sedangkan
keberadaan glucoronic acid dan ,glucosanzine
tidak terdeteksi ada pada kom~onen
kimia polisakarida kulit coklat dan kulit pisang yang mendapat periakuan ambniasi
0% dan 3% urea.
