The aim of this study was to produce an edible film from egg white protein powder and the theological, mechanical properties,permeability and scanning electron microscopy (SEM) of the prepared films were determined. The thickness, tensile strength , elongatio ,% solubility of produced by edible film with rosemary essential oil was the highest, followed by that of egg protein powderbased film with tripolyphosphate (TPP). Therefore, the addition of rosemary essential oil or (TPP) to egg white protein powder films have the potential to provide a safe edible films decreased microbial growth and consequently prolonged the shelf life of chicken patties, As well as improved the chemical changes and sensory properties of the chicken patties. The substances used in this experiment were , film with glycerin (A) , film with sorbitol (B), film with rosemary essential oil (C) and film with tripolyphosphate (D) compared with (CL) on quality attributes and prolong shelf-life of chicken patties during storage. All products were stored at (4±1°C) for 30 days and the quality parameters such as total volatile nitrogen (TVB-N), thiobarbituric acid (TBA), WHC, plasticity, pH, weight loss, moisture content , total bacteria count, psychrophilic bacteria (Psy) and molds and yeasts (M&Y) were determined. The results observed that treatment (C) was the best treatment in terms of reduction of microbial load followed by treatment (D) followed by treatment (B) until 30 days of storage as compared to control (CL). The levels of decrease in chemical and microbial load in the samples from both of the edible films were related good quality chicken patties. As well as on the same physic-chemical tests and sensory. It is clear that the edible coating and films of the aromatic essential oils and the (TPP) have kept the Quality of chicken patties up to 30 days of storage.
The aim of this study was to produce an edible coating and film from gelatin powder and the incorporating it with action of silver AgNo3 with extracts Luria leaves/glacial acetic acid and the rheological properties, particle size distribution, zeta potential emulsion, and scanning electron microscopy (SEM) of the prepared films were determined. The thickness, tensile strength, elongation, % solubility of produced by edible film with silver AgNo3 with extracts Luria leaves/glacial acetic acid was the highest, followed by that of gelatin powder-based film with extracts Luria leaves/glacial acetic acid. Therefore, the addition of silver AgNo3 with extracts Luria leaves/glacial acetic acid or extracts Luria leaves/glacial acetic acid to gelatin powder films have the potential to provide a safe edible films decreased microbial growth and consequently prolonged the shelf life of strawberry, As well as improved the physio-chemical changes properties of the strawberry .The substances used in this experiment were , film with a 0.25ml , film with b 0.50ml , film with c 0.75 ml , film with d 1.0 ml, film with f 0.25 ml, film with g 0.50 ml, film with h 0.75 ml, film with i 1.0 ml compared film with (e and j) on quality attributes and prolong shelf- life of strawberry were studied during storage at 0.5°C and 90-95% relative humidity (RH) for 12 days from storage . The results observed that was the best treatment in terms of reduction of microbial load followed by treatment (a, b, c and d) followed by treatment (f, g, h and i) until 12days of storage as compared to control (e and j) without nanomaterials additives, during the manufacture of the films. The levels of decrease in chemical and microbial load in the samples from both of the edible films were related good quality strawberry. On the other hand observed that coefficients ( a, b, c and d ) gradually increased with increasing the concentration of antimicrobials action of extract Luria leaves/acetic acid glacial synthetic nanoparticles size 0.25, 0.50, 0.75 and 1.0 the results were as follows 332.3, 407.0, 411.0 and 577.0 respectively as compared control (e), which was higher than treatments 660.2. It was found that the treatments of antimicrobials action of silver nitrate AgNo3 and extract Luria leaves/acetic acid glacial synthetic nanoparticles size (f, g, h, i ) gradually decreased with increasing concentration of 0.25, 0.50, 0.75 and 1.0 and the results were 17.7, 14.50, 12.64 and 5.70 as compared the control (J), which was significantly higher than the coefficients 71.26. It is clear from this that the concentration of silver nitrate AgNo3 and extract Luria leaves in treatments (f, g, h, I and j) was better than other extract luria leaves/acetic acid glacial (a, b, c, d and e).
