Abstract: Preparation of cellulose
film from nata
de pina, a
product of pinapple
fermentation, using acetobacter
xylinum was done at room temperature for
15 days. The aim of the research is to investigate the effect of sugar
concentration and pH on film quality. The fermentation run at sugar
concentration of 0, 5, 7.5, 10 and 12.5%
and at pH of 3, 5 and 7. Results show that the
best nata de
pina was obtained
at sugar concentration
of 10% and
pH 5. At
these conditions, maximum nata
precipitates rendemen was
26,80%, with a
moisture content of 80,55%,
and the thickness
of 3,30 cm.
The product nata
then can be
used to produce cellulose film.
The characteristic of the produced
film were 8,20
Kgf/mm2 and 11,71%
for maximum tensile strength and elongation, respectively.
