The use of plastic packaging as food wrappers cannot be separated from everyday life. This will certainly cause many environmental problems because the nature plastics that are difficult to degrade naturally. One alternative overcome in products is edible film. film a thin layer used coating for can consumed and environmentally friendly. made gelatin raw material. Gelatin has properties form ge...

Background: Newer antidiarrheal agents include the mucoprotectants gelatin tannate and xyloglucan. Methods: Rat models of cholera toxin (CT)-induced water secretion were used to evaluate mucoprotective effects tannate, xyloglucan, related compounds. Results: Oral pretreatment for 4 days with (250 500 mg/kg/day), but not tannic acid or (both 125 blocked CT-induced intestinal secretion. was also ...

A new type of protein/polyphenol microcapsules on the basis of naturally occurring polyphenol (-)-epigallocatechin gallate (EGCG) and gelatin, type A, was obtained using the layer-by-layer (LbL) assembly method. The microcapsules show a more pronounced dependence of permeability on molecular weight of permeating substances than commonly used polyallylamine/polystyrene sulfonate capsules. The re...

Due to the weak regeneration potential of cartilage, there is a high clinical incidence of articular joint disease, leading to a strong demand for cartilaginous tissue surrogates. The aim of this study was to evaluate a gelatin-based hydrogel for its suitability to support chondrogenic differentiation of human mesenchymal stem cells. Gelatin-based hydrogels are biodegradable, show high biocompa...

Keratin solution was separately blended with collagen, gelatin, sericin and starch for films preparation. All the blended films had smooth surfaces without phase separation, except the keratin/ starch blend film. The native keratin film showed small particles embedded in all the film surfaces that resulted in them being rough. The structure of the native keratin film changed from beta-sheet to ...

In the present work an environmentally friendly recycling system to peel away the base coat from the X-ray film by using an enzyme was developed. Bromelain, a proteolytic enzyme extracted from the waste apex of pineapple was used for stripping the silver layer on the exposed film by hydrolysis of gelatin. The collected film can be reused for the manufacturing of X-ray film or other materials li...

Regeneration of the dura mater following duraplasty using a collagen film, chitosan or combination both with gelatin, was studied in craniotomy and penetrating brain injury model rats. Collagen autofluorescence regenerated evaluated confocal microscopy excitation at λem = 488 nm 543 nm. An increase regeneration extracellular matrix connective tissue an fluorescence were detected 6 weeks after ...

A new miniature interferometer has recently been developed for monitoring the changes of film thickness and refractive index, wherein a semiconductor laser and a photodiode detector are integrated to form a laser/detector hybrid. The laser light is collimated by a lens. When the laser light hits a film, it is reflected twice by the two interfaces between the film and the surrounding mediums. Th...
