Gelatin was extracted from hydrolyses of collagen muscle bonds. Gelatin was of two types. Type A was obtained from acidic and type B from alkaline procedures. In the present study we used sturgeon fish skin to produce 25 samples of gelatin. Microbiological and chemical examinations were conducted on the gelatin samples. Based on the results obtained from the chemical examination, gelatin type A...

In a preliminary statement the writer (1) presented the proposition that the minimum physical properties of gelatin (conductivity, osmotic pressure, viscosity, maximum opacity) which are usually thought to define its isoelectric point are propert’ies of pure gelatin, and that pure gelatin is not isoelectric; that pure gelatin from lime-conditioned stock is a weak acid which in an electrical fie...

in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

Consumption of food products derived from porcine sources is strictly prohibited in Islam. Gelatin, mostly derived from bovine and porcine sources, has many applications in the food and pharmaceutical industries. To ensure that food products comply with halal regulations, development of valid and reliable analytical methods is very much required. In this study, a species-specific polymerase cha...

This study investigated the effects of lubricin on the gliding of repaired flexor digitorum profundus (FDP) tendons in vitro. Canine FDP tendons were completely lacerated, repaired with a modified Pennington technique, and treated with one of the following solutions: saline, carbodiimide derivatized gelatin/hyaluronic acid (cd-HA-gelatin), carbodiimide derivatized gelatin to which lubricin was ...

Normal mouse spleen cells were fractionated in dishes coated with thin layers of DNP-gelatin or NIP-gelatin, which were insoluble at 4 degrees C. Highly viable cells were recovered from the dishes by melting the gel at 37 degrees C. NIP3- gelatin layers bound approximately 0.1% and DNP4-gelatin layers 0.5% of normal spleen cells. Increasing numbers of low affinity cells were bound with increasi...

BACKGROUND We have observed patients clinically allergic to red meat and meat-derived gelatin. OBJECTIVE We describe a prospective evaluation of the clinical significance of gelatin sensitization, the predictive value of a positive test result, and an examination of the relationship between allergic reactions to red meat and sensitization to gelatin and galactose-α-1,3-galactose (α-Gal). ME...

–Biomaterials are used in regenerative medicine, implantable materials, controlled release carriers or scaffolds for tissue engineering. Biological dressings like fibrin glue, gelatin sheets, chitosan films, collagen is popular for quicker wound healing. These polymers when used in combination such as fibringelatin, fibrin-chitosan has shown better results, than when used alone. Thus, the prese...

The combination of cationic and anionic dyes with proteins of tissues is difficult to interpret chemically because the reactions depend upon many factors. Among these are the physicochemical conditions of staining and the chemical structure, purity, and physical &ate of the pr0tein.l The study of these factors may be simplified by employing “model tissues” but the solid proteins heretofore avai...

Gelatin-based films with an immobilized enzyme designed for extending the stability of the protein in dry, non-powder configuration with precise dosing attributes were subjected to stress conditions of temperature and relative humidity. β-galactosidase was used as model functional protein. The film configuration preserved the activity of the enzyme under the different storage conditions investi...
