“…The HPC films presented preferable water vapor barrier properties, by being relatively hydrophobic. HPC–KF complex films possessed comparatively low values of WVP, which may be attributed to the high tendency to form tight junction zones between KF and HPC molecules (Cheng, Karim, & Seow, ; Huang et al., ; Lopez‐Rubio et al., ). The inclusion of L. paracasei brought about a significant increase in WVP when compared to HPC–KF complex films.…”

“…For biocompatibility, nontoxicity, mechanical resistance, and film‐forming properties, konjac glucomannan (KGM) has been made full application in food industry. Konjac flour (KF), which is mainly composed of KGM, has the great potential to fabricate edible films, packaging, or coatings (Huang, Yang, Chu, Wu, & Tsai, ). Considering the structural similarities between HPC and hydroxypropyl methyl cellulose (HPMC), as well as the KF mainly consisting of KGM, it can be inferred that there may be intermolecular interactions when HPC and KF combined in accordance with the interaction of HPMC and KGM (Bo & Shao, ; Pang, Huang, Wu, & Wang, ).…”

Bioactive composite films were obtained by adding Lactobacillus paracasei into a hydroxypropyl cellulose (HPC)‐konjac flour (KF) matrix through a casting method. The mechanical, optical, and barrier properties were tested to determine the influence of the addition of lactobacilli into complex films. For purpose of evaluating the surface morphology of the composite films, scanning electron microscopy and atomic force microscopy were carried out. Fourier transform infrared spectroscopy and X‐ray diffraction analyses were conducted to evaluate intermolecular interactions and crystallinity, respectively. Moreover, the microbial viability of the lactobacilli and the antibacterial activities of the bioactive films against pathogenic organisms were measured. The results indicated that the mechanical properties, crystalline properties, oxygen permeability, and color characteristics were not notably altered; nevertheless, the gloss and water vapor barrier properties were relatively weakened by the incorporation of L. paracase. The HPC–KF–L. paracasei films were effective in inhibiting both gram‐positive (Listeria monocytogenes, Staphylococcus aureus) and gram‐negative (Escherichia coli, Salmonella typhimurium) pathogens, and the films can retain physical property and antibacterial activity within a storage period of 30 days. The composite films, acting as suitable carriers for L. paracasei and possessing noteworthy bacteriostatic activities, could be developed as bioactive packaging for preserving food. Practical Application For the sake of the high desires of consumers for food safety and quality, the development of innovative bioactive packaging has attracted wide attention. In this work, the prepared films containing lactic acid bacteria showed great physical property, antipathogenic activity, and fresh‐keeping property preservation, and have great application potential in fresh food preservation.

“…Polysaccharides have received much attention in the biomedical and food area over the past few years. Among these materials, konjac glucomannan (KGM) is recognized as a preferred natural polysaccharide [ 32 ] because of its nontoxicity [ 33 ], excellent biodegradability [ 34 , 35 ] and biocompatibility [ 36 ] and good film-forming ability [ 33 ]. KGM gels and films are thus promising candidates for wound dressing and food packaging [ 37 , 38 ].…”

Three-dimensional nanofibers cryogels (NFCs) with both thermally-tolerant and mechanically-robust properties have potential for wide application in biomedical or food areas; however, creating such NFCs has proven to be extremely challenging. In this study, konjac glucomannan (KGM)/poly (lactic acid) (PLA)-based novel NFCs were prepared by the incorporation of the mussel-inspired protein polydopamine (PDA) via a facile and environmentally-friendly electrospinning and freeze-shaping technique. The obtained KGM/PLA/PDA (KPP) NFCs were characterized by field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and compressive and tensile test. The results showed that the hierarchical cellular structure and physicochemical properties of KPP NFCs were dependent on the incorporation of PDA content. Moreover, the strong intermolecular hydrogen bond interactions among KGM, PLA and PDA also gave KPP NFCs high thermostability and mechanically-robust properties. Thus, this study developed a simple approach to fabricate multifunctional NFCs with significant potential for biomedical or food application.
