▼ Edible packaging films have received a considerable attention in recent years because of their advantage over the synthetic films in the reduction of environmental pollution. The aim of the research was development of optimal edible packaging bio-films from gelatin and glycerol by varying the concentration of (5,10 and 15 wt/wt) and (4,8,12 and 16v/wt) respectively with the main responses of physical property (solubility, swelling and WVTR) and mechanical property (tensile strength and elongation at break), and re-preparing a packaging bio-film by adding Nigella Sativa seed extract together with gelatin and glycerol optimal response results and finding its antimicrobial activities of the developed packaging bio-films against foodborn pathogens. The factorial response optimizer results were gelatin concentration (10g gelatin/100ml aqueous solution) and glycerol concentration (4ml glycerol/100ml aqueous solution), solubility (54.76%), swelling (43.99%), WVTR (0.145gm/day cm ), tensile strength (20.302Mpa), and elongation at break (14.95%). The optimal re-prepared packaging bio-films with the addition of Nigella Sativa seed extract with the concentration (12.5%, 25% and 50%) were also analyzed its Antimicrobial activities against targeted food-born pathogens (Escherchia coli, Salmonella typhi, Staphylococcus aureus, and Pseudomonas aeruginosa). The Nigella Sativa seed extract showed result (30, 23 and 19.5mm inhibition zone on Escherchia coli , 30, 25.5 and 20mm inhibition zone on Salmonella typhi and 30, 24 and 20 inhibition zone on Staphylococcus aureus with the concentration of Nigella Sativa seeds extract of 75, 50 and 25% for the mentioned pathogens respectively) except for (Pseudomonas aeruginosa) whereas the bio-film that contain the Nigella Sativa seed extract showed only surface inhibition. In conclusion, this study confirms that the bio-films developed from this gelatin, glycerol and Nigella Sativa seed extract had an antimicrobial activity on food-born pathogens. Therefore, this may be used for wide range of food packaging on perishable vegetables and fruits in order to reduce their vulnerable microbial growth and extend their shelf stability of food products.

▼ Electrostatic coating is a technology credited with significant processing and cost improvements in snack industry. The impact of this technology on consumer acceptability of the coated products is not well understood. This study seeks to map the driving factors for process improvement by electrostatic coating in relate to consumer acceptability. Barbeque, sour cream and onion, salt and vinegar, nacho cheese and salsa seasonings were applied to potato chips at 0 and 25 kV. Sensory evaluation determined that electrostatically coated chips had better coating uniformity and were significantly preferred to nonelectrostatically coated samples. Electrostatic coating was more even as measured by colorimeter. Particle size and evenness of coating did not significantly affect perceived flavor intensity. Electrostatic coating significantly increased transfer efficiency and decreased dust over nonelectrostatic coating. Particle size and flowability can be used to predict transfer efficiency and dustiness. Chargeability was also important for electrostatic transfer efficiency. Particle size was the most important factor overall. The study also investigated the effect of powder composition and particle size within a powder on transfer efficiency. Powders were grouped based on their protein, carbohydrate, salt and acid contents. Powders were coated on foil strips. Particle sizes were varied in the range of 19-165 micron. The transfer efficiency of nonelectrostatic and electrostatic coating, powder flowability and resistivity were determined. Size and cohesiveness influenced both coating methods while powder composition and resistivity only affected electrostatic coating. The effects and interactions of powder size and composition in relation to process efficiency contradicted those previously reported. Nonelectrostatic transfer efficiency increased to a maximum before either leveling-off or decreasing with increasing particle size. Electrostatic transfer efficiency either decreased or reached a maximum at a certain particle size before decreasing with increasing particle size. Free flowing powders increased both nonelectrostatic and electrostatic transfer coating efficiency. Powders became more cohesive when particle size was decreased. The conflicting effects of size and flowability caused the transfer efficiency peak of some powders. Powder composition influenced powder resistivity and flowability. Protein yielded the highest electrostatic transfer efficiency while carbohydrate was the lowest. The average improvement in transfer efficiency by electrostatic coating was 20%.
