a poly(lactic acid) (pla) based nanocomposite active packaging has been developed for the controlled release of tert-butylhydroquinone (tbhq) antioxidant. pla based active films were loaded with tbhq (3%wt) or mixture of modified cellulose nanofiber (mcnf) (8%wt) and tbhq (3%wt) to obtain active and nanocomposite active films, respectively. release studies indicated that the release rate of tbh...
fatty acid modified cellulose nanofibers (mcnfs) and tbhq antioxidant were added to poly(lactic acid) (pla) film. the combined effects of the mcnfs and tbhq on the morphological, thermal, mechanical and barrier properties of pla film were analyzed. the morphology of fracture surfaces evaluated by field emission scanning electron microscopy (fe-sem). xrd results showed that the crystallinity of ...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
the effect of enzymatic treatment time of microbial transglutaminase (mtgase) on the characteristics of whey protein isolate (wpi) films was investigated. results shown that the properties of mtgase-treated films were affected by increasing the enzymatic treatment time. enzymatic treatment at lower incubation time, i.e. for 1 h, significantly resulted in higher values of tensile strength (ts) a...
