Overall, results indicated that the HGP/HBC composites prepared using the DA method demonstrated the highest rehydration ability among the composite films evaluated.Ī.O.A.C. The 1 min rehydrated HGP/HBC composites possessed similar mechanical properties to the original wet type composites. The high hydrophilic property of HGP resulted in a rehydration ratio of approximately 180 % at a HGP/HBC ratio of 4.5:1 (W/W) in DA composites. According to SEM images, gelatin and HGP successfully penetrated the cellulose network in composite films prepared using both immersion and adsorption (DA) methods. The HGP/HBC nanocomposites exhibited higher rehydration ratios than composites prepared with gelatin. The HGP with molecular weights <9 kDa were obtained by hydrolyzing gelatin with a combination of 1 % alcalase and 1.5 % pronase E at 50 ☌ for 2 h. ![]() The present study investigated the rehydration ability of composites of hydrolyzed gelatin peptides (HGP) and hydroxypropylmethyl cellulose-modified BC (HBC). However, dried BC exhibits poor rehydration ability. Bacterial cellulose (BC) is a nanoscale and useful biomaterial with a fine fiber network and high water holding capacity.
