Stearic acid was incorporated into whey protein through emulsification to produce films. Whey protein films were prepared by dispersing 6.5% protein in distilled water. Glycerol was the plasticizer agent. Stearic acid was added at different levels (0.0 to 1.0%) and the films were analyzed at different pHs (5.0, 6.0, 7.0 and 9.0). The emulsion films were evaluated for mechanical properties, wate...

Cereal Chem. 70(4):426-429 Edible films were produced from wheat gluten-based film-forming solutions. One film was produced as a control. Other types came from subjecting control films to three different soaking treatments. Three additional films were also produced by modifying the control film-forming solution. For all films, selected physical properties and permeability to water vapor and oxy...

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 and glyoxal on the mechanical properties, water vapor permeability, solubility and color parameters of gelatin-based films. Formaldehyde and glyoxal were added to the filmo...

a suitable option for manufacture of packing materials is the use of clay and silver nano particles. these materials help create optimal relative impermeable quality, in addition to other features being improved. moisture-packed bread by use of these materials prevent water vapor loss and therefore reduce the level of bread becoming stale. in this study, seven types of nano-films with different...

The mechanical and water vapor permeability of starch/carrageenan cast films were investigated, the rheological properties of starch/carrageenan blends were also studied. The blends were prepared by different concentrations of starch and carrageenan. Three concentration of starch (0.75%, 1% and 1.25%) and two concentrations of carrageenan (0.5% and 0.75%) were used with adding 0.5% glycerol as ...

The present study aimed to determine the physical, chemical, and textural properties of goatskin used in production Tulum cheese traditional industrial ripening conditions. Natural conditions (caves) some parameters (temperature, humidity, oxygen, CO2 values) cold storage dairy plants were examined between March October. It was determined that temperature moisture content natural cave where car...

−− A mathematical model was developed to describe mass transport in polymeric films based on modifications of Fick’s law in a continuous macroscopic approach. The purpose of this work was specifically to model the transport of water vapor and oxygen in polymeric films at the pore level, based on physical aspects of the condensation process and the morphology and connectivity of the porous mediu...
