In the present study, circular economy based and potentiall
y low-cost
poly(3-hydroxybutyrate-
co
-3-hydroxyvalerate) (PHBV) was produced by mixed microbia
l
cultures derived from fruit pulp, an industrial by-product
of the juice industry. Three
different chemical routes, namely non-extraction, extrac
tion with sodium hypochlorite
(NaClO), and extraction with chloroform, in combination wi
th filtering and centrifugation,
were explored to purify the biopolymer and find the most optim
al solution for its
processing
via
electrospinning. The resultant ultrathin fiber mats of the d
ifferent
extracted PHBV materials were thermally post-processed at
different temperatures
in order to obtain continuous films adequate for food packagi
ng applications. The
resultant films were characterized in terms of morphology, c
rystallinity as well as
thermal, mechanical, and barrier properties. The results s
howed that extraction with
both chloroform and NaClO with a post-treatment of filtering
and centrifugation of the
PHBV-containing biomass were necessary refining steps to al
low its processing by
electrospinning. In particular, the PHBV extracted with ch
loroform presented the highest
degree of purity, resulting in more transparent films with lo
wer wettability and higher
flexibility. The here-formulated electrospun films made of b
iomass derived from biowaste
exhibit great potential as interlayers or coatings for food
biopackaging applications. [-]
