Enhancing water repellence and mechanical properties of gelatin films by tannin addition
(Elsevier, 2010-04-18)
In order to reduce pollution caused by traditional non-biodegradable plastic films, renewable raw materials from plants and wastes of meat industries have been employed in this work. A hydrolysable chestnut- tree tannin ...
NMR and conductivity study of gelatin-based polymer electrolytes
(TAYLOR & FRANCIS LTD, 2008)
Nuclear Magnetic Resonance spectroscopy (NMR) and complex impedance spectroscopy have been used to study gelatin-based polymer electrolytes plasticized with glycerol and containing lithium perchlorate. The studied samples ...
Properties of chemically modified gelatin films
(Brazilian Society of Chemical Engineering, 2006-03-01)
Edible and/or biodegradable films usually have limited water vapor barriers, making it difficult to use them. Thus, the objective of this work was to evaluate the effect of a chemical reticulation treatment with formaldehyde ...
Application of Gamma Radiation on Hard Gelatin Capsules as Sterilization Technique and Its Consequences on the Chemical Structure of the Material
(Springer, 2019-07-01)
Hard capsules are made from gelatin, an organic polymer obtained through the hydrolysis of collagen present in animal tissues. Gelatin can be degraded by microorganisms and some strategies can be used to control contaminating ...
Characterization of Cross-linked Polyampholytic Gelatin Hydrogels through the Rubber Elasticity and Thermodynamic Swelling Theories
(Elsevier, 2009-11)
A new approach is proposed to characterize polyampholytic gelatin hydrogels, cross-linked covalently with glutaraldehyde. An experimental methodology involving simple mechanical extension and compression and equilibrium ...
Turmeric oleoresin encapsulated by spray drying in maltodextrin/gelatin and starch/gelatin blends: storage stability and water sorption
(2022-01-12)
Turmeric oleoresin is a widely used a flavoring agent and a food color with relevant nutraceutical properties. It is obtained by organic solvent extraction of turmeric (Curcuma longa L.). Microencapsulation is a good ...
Physicochemical properties of films based on bovine gelatin cross-linked with 1,4-butanediol diglycidyl ether
(Springer, 2015-04-21)
The effectiveness of 1,4-butanediol diglycidyl ether (BDDGE) as a cross-linking agent of bovine gelatin films plasticized with D-sorbitol intended for food packaging is reported. Free-standing films were produced by casting ...
Effect of surfactants on the functional properties of gelatin-polysaccharide-based films
(SPRINGER, 2011)
The aim of this study was to evaluate the effects of the addition of surfactants sodium stearoyl lactate (SSL) and sucrose ester (SE) on the functional properties of films produced with polysaccharides mixtures ...
Effect of surfactants on the functional properties of gelatin-based edible films
(ELSEVIER SCI LTD, 2011)
The aim of this research was to evaluate the plasticizing effect of natural surfactants lecithin or yucca extract from Yucca schidigera on gelatin-based films Films containing yucca extract showed higher tensile strength ...
