Abstract
Alginate is a naturally derived biocompatible polymer widely used as a drug or food adjuvant. However, its usage as a biofunctional material has been confounded by the lack of shapable strategies. In this study, we report an easily applied ionic cross-linking strategy for fabricating shapable multifunctional SA-Ca(II) hydrogels employing the process of regulated diffusion. The fabrication proceeds in neutral solutions under ambient conditions. The obtained SA-Ca(II) hydrogel presents tunable moduli ranging from 4 to 30 kPa, resembling a series of human tissues. The tunable mechanical strength provides differentiation signals for stem cell polarization. The hydrogel film can lift a weight of 10 kg. The hydrogel can be prepared into various shapes and remains stable over one year upon rinsing in deionized water, but rapidly degrades in alginate lyase solutions. Subcutaneously embedded SA-Ca(II) hydrogels in mice show high biocompatibility and degrade over 4 weeks accompanied by hair follicle regeneration. Wearable protections as well as stimuli-responsive electronic circuits are then achieved, which not only protect the model body against high-temperature environments but also show warning signals when the protection loses effectiveness because of high temperatures. Overall, these results demonstrate that our SA-Ca(II) hydrogel offers appealing comprehensive functionalities from multifaceted perspectives, including mechanical strength, economic and environmental considerations, transparency, forming capability, biocompatibility, and conductivity.

Abstract
Due to the high moisture-associated typical rheology and the changeable and harsh processing conditions in the production process, packaging materials for meat products have higher requirements including a sufficient mechanical strength and proper ductility. Collagen, a highly conserved structural protein consisting of a triple helix of Gly-X-Y repeats, has been proved to be suitable packaging material for meat products. The treated animal digestive tract (i.e. the casing) is the perfect natural packaging material for wrapping meat into sausage. Its thin walls, strong toughness and impact resistance make it the oldest and best edible meat packaging. Collagen casing is another wisdom of meat packaging, which is made by collagen fibers from hide skin, presenting a rapid growth in casing market. To strengthen mechanical strength and barrier behaviors of collagen-based packaging materials, different physical, chemical, and biological cross-linking methods are springing up exuberantly, as well as a variety of reinforcement approaches including nanotechnology. In addition, the rapid development of biomimetic technology also provides a good research idea and means for the promotion of collagen's assembly and relevant mechanical properties. This review can offer some reference on fundamental theory and practical application of collagenous materials in meat products.

Abstract
Film wound dressings represent one of the options in wound therapy. Various polymers can be used for their production. Currently, research focuses on materials of natural origin, more friendly to the human body, which are in many cases able to participate actively in the wound healing process. These include polyamino acids of bacterial origin, substances that are biodegradable, non-toxic, and have a great potential for an application not only in the medical field. From the point of view of film wound dressing formulation, poly-γ-glutamic acid (PGA), as a film-forming agent, and poly-ε-lysine (PL), characterized by antimicrobial activity, are of interest from this group. Therefore, the aim of our experiment was to prepare films consisting of PGA or a combination of PGA and PL with the addition of different plasticizers. The films were prepared by solvent evaporation method and then evaluated for their organoleptic (appearance, colour, transparency, ease of handling), physicochemical (thickness, density, opacity, surface pH), and mechanical properties (tensile strength and tear resistance). As a result, films showing mutual compatibility between the two polymers were obtained, with satisfactory properties for wound application.

Abstract
Biodegradable films are a promising strategy to reduce the environmental impact caused by conventional plastics commonly used in agriculture. This study focused on the production and characterization of Konjac glucomannan (KGM) and alginate (ALG) based films enriched with sugarcane vinasse (VIN), a nutrient-rich wastewater generated in large volumes by the sugar-ethanol producing industries. ALG, KGM and ALG/KGM blended (50:50) films were produced by casting and treated with calcium ions (Ca2+) (ALG films) and a combination of Ca2+, alkali, and ethanol (KGM and ALG/KGM films). Vinasse addition tended to reduce transparency and water resistance of the films and had less effect on their mechanical properties. Crosslinking of ALG films resulted in enhanced mechanical properties and reduced moisture content, water solubility, swelling, water vapor permeability, and flexibility. KGM films were less impacted by crosslinking/deacetylation but showed improved water resistance while maintain a high degree of swelling (290% and 185% for KGM and KGM/VIN films respectively). Blended films exhibited characteristic properties of the two biopolymers and adequate compatibility indicated by Fourier transform infrared spectroscopy (FTIR) and morphologies. Vinasse-added ALG/KGM films represent a novel nutrient-enriched, bio-based material for agricultural applications and could help to face the environmental challenges imposed by vinasse disposal.

Abstract
Collagen/cellulose films were made by the blend solutions of collagen, cellulose in this paper. To begin with, collagen and cellulose was dissolved in 1-allyl-3-methylimidazolium chloride ([Amim]Cl). The structure of the blend films was characterized by FTIR and XRD. The effects of weight ratio between the two polymers on light transmittance, tensile strength, elongation at break and water absorption of the film were studied. The results showed that there were strong interactions and good compatibility between collagen and cellulose in the film and the polymers have strongest interactions at the mixing ratio of 5:5. The blend films possess better properties such as mechanical and water absorption properties than those made of single polymer.

Abstract
Collagen gels have been investigated for a number of applications in tissue engineering because of their excellent biological properties. However, their limited mechanical behavior represents a major bottleneck for clinical use, especially for vascular tissue engineering. The targeting of their mechanical properties may be envisaged by the addition of other biopolymers, such as konjac glucomannan (KGM), a neutral high-molecular weight polysaccharide extracted from the tubers ofAmorphophallus konjac, which has already been studied for biomedical applications due to its biocompatibility and biodegradable activity. In the present study, reconstituted collagen gels were prepared at pH 10 and room temperature, by mixing collagen with NaOH, NaCl and 0.05 to 0.2% of KGM. Collagen fibrillogenesis was monitored by spectrophotometric analysis at 310 nm. Gel samples were analyzed by compression tests, FTIR and SEM. Comparing to the control, the addition of KGM reduced the half-time (t1/2) of gelation fromca. 3 h to 2 h and the mechanical tests showed increases in the compressive strain energy of up to 3 times, and in compressive modulus of almost 4 times. Scanning electron images of collagen gel samples with KGM revealed the presence of micro-domains of KGM in the collagen matrix, revealing a phase separated scaffold for vascular tissue engineering.

Abstract
BACKGROUND Films made from different protein (P) or polysaccharide (PS) materials have widely different properties. The objective of this study was to determine whether whey protein isolate (WPI)-PS blended films possess a combination of properties intermediate and possibly superior to WPI or PS film alone. RESULTS Oxygen permeability (OP) and tensile strength (TS) for PS-WPI blended films were intermediate between the OP and TS properties of pure methycellulose (MC), hydroxypropylmethylcellulose (HPMC) or sodium alginate (SA) film and pure WPI film. Starch-WPI blends gave the weakest films. Water vapor permeability values for all pure and blended films were similar. Blended films made of MC, HPMC or SA with WPI had lower transparency than pure MC, HPMC, SA or WPI films. Differential scanning calorimetry thermograms obtained from the blended films exhibited a single glass transition temperature (T(g) ) at an intermediate value between the T(g) values of the pure films. CONCLUSIONS Whether properties of PS-WPI blended films are intermediate to properties of the pure PS and WPI film depends on the particular PS and specific property. In the case of MC or HPMC with WPI, the blended films reflect the higher TS of the PS and lower OP of the WPI.

Abstract
The present study describes preparation and characterization of a thermally stable and biodegradable biopolymer using collagen and a natural polymer, alginic acid (AA). Required concentration of alginic acid and collagen was optimized and the resulting biopolymer was characterized for, degree of cross-linking, mechanical strength, thermal stability, biocompatibility (toxicity) and biodegradability. Results reveal, the degree of cross-linking of alginic acid (at 1.5% concentration) with collagen was calculated as 75%, whereas it was 83% with standard cross-linking agent, glutaraldehyde (at 1.5% concentration). The AA cross-linked biopolymer was stable up to 245°C and Exhibits 5-6-fold increase in mechanical (tensile) strength compared to plain collagen (native) materials. However, glutaraldehyde cross-linked material exhibits comparatively less thermal stability and brittle in nature (low tensile strength). With regard to cell toxicity, no cytotoxicity was observed for AA cross-linked material when tested with mesenchymal cells and found degradable when treated with collagenase enzyme. The nature of bonding pattern and the reason for thermal stability of AA cross-linked collagen biopolymer was discussed in detail with the help of bioinformatics. A supplementary file on efficacy of AACC as a wound dressing material is demonstrated in detail with animal model studies.
