Oil-Added Agar Gelatin Edible Films for Kashar Cheese Packaging.

In recent years, there has been a growing interest in edible and biodegradable films due to their sustainability, environmental friendliness, and their functionality. In this work, oil-added agar-gelatin films were prepared and characterized in terms of water content, degree of swelling, water solubility, antioxidant activity, and antimicrobial activity. The possibility of using these edible films for Kashar cheese packaging during cold storage was investigated.

New biocompatible antibacterial wound dressing candidates; agar-locust bean gum and agar-salep films.

Agar has numerous applications in biomedical and biopharmaceutical fields in gel form. However the hard and tough nature of agar films and their vulnerability to microbial attacks prevent their usage in wound dressing applications. In this work, agar - locust bean gum (LBG) and agar - salep films were prepared for the first time to improve its physical, antimicrobial and cell viability properties.

A detailed investigation of the effect of calcium crosslinking and glycerol plasticizing on the physical properties of alginate films.

Alginates attract growing interest due to their biocompatible and biodegradable nature. Here, a wide spectrum of glycerol added alginate films (from 0 to 30% w/w, glycerol/alginate) were prepared and crosslinked by four different concentrations of calcium chloride solutions (0.5, 1, 1.

Stress relaxation and humidity dependence in sodium alginate-glycerol films.

The control of viscoelastic properties of alginate biopolymer that mimics the matrix properties of biological substrates plays an important role for the success of its biomedical applications. For this purpose stress relaxation behavior of glycerol plasticized sodium alginate films is characterized at room temperature as a function of the glycerol concentration ranging up to 40%. A series of experiments are thus conducted at relative humidity levels of 38 ± 1% and 51 ± 1%.

Evolution of composition, molar mass, and conductivity during the free radical copolymerization of polyelectrolytes.

Despite their importance in biological and technological contexts, copolymeric polyelectrolytes (or "copolyelectrolytes") continue to present challenges to theorists and experimentalists. The first results of a unified approach to the kinetics and mechanisms of copolyelectrolyte synthesis and the physical characteristics of the resulting polymers are presented. The free radical copolymerization of 4-vinylbenzenesulfonic acid sodium salt and acrylamide was monitored using automatic continuous online monitoring of polymerization reactions (ACOMP), from which the average bivariate composition and mass distributions were determined.
