1. Impact of whey protein isolate coatings containing different antimicrobial agents on sliced bologna-type sausage during refrigerated storage
Abstract In this study, we aimed to determine the possibility of using the edible whey protein isolates coatings containing different antimicrobial agents on the bologna-type sausage slices and the inactivation effects of these coatings against Listeria innocua. For this purpose, edible whey protein isolates (WPI) coatings were prepared to contain essential

6. Silver Nanocoatings at Large Length Scales: Influence of the AgNPs Morphology and Capping Agents on the Coating Chemical Stability and Antimicrobial Effect
We assessed at multiple length scales (nanometers to millimeters) the nanocoatings of silver nanoparticles (AgNPs) on model SiO2/Si substrates. The coatings from biogenic AgNPs (from yeasts Rhodotorula glutinis and Rhodotorula mucilaginosa) were compared to those formed from "synthetic" AgNPs capped with citrate and sodium dodecyl sulfate (SDS). With computa

7. Characterization and antimicrobial performance of nano silver coatings on leather materials
In this study, the characterization and the antimicrobial properties of nano silver (nAg) coating on leather were investigated. For this purpose, turbidity, viscosity and pH of nAg solutions prepared by the sol-gel method were measured. The formation of films from these solutions was characterized according to temperature by Differential Thermal Analysis-The

8. Biossurfactantes: propriedades anticorrosivas, antibiofilmes e antimicrobianas
Due to the importance of biofilms in the food industry, new products are being developed to enhance the efficiency of cleaning food-contact surfaces. Biosurfactants could be an alternative to synthetic products. The major advantages of biosurfactants over synthetic detergents are their low toxicity and highly biodegradable nature. Biosurfactants may also exh

9. Combined effects of postharvest heat treatment and chitosan coating on quality of fresh-cut mangoes (Mangifera indica L.).
The influence of heat treatment combined with coating on sensory quality, physico-chemicals characteristics (firmness, colour, pH, titratable acidity, total soluble solids and total carotenoids content) and microbiological quality of fresh-cut mangoes were studied. Whole mangoes (Mangifera indica cv ?Tommy Atkins?) were subjected to hot water dipping (HWD) a

10. Revestimento ativo enriquecido com aminoácidos em feijão-comum / Active coating enriched with amino acids in common bean
Beans is one the most consumed legumes in developing countries. However, this food is also consumed in developed countries, although in small amounts. Bean is the third legume more important of world. The parameters that confer the bean its technological and nutritional quality are related with genetic variation, and environmental and their interaction. The

11. Inactivation of Vegetative Cells, but Not Spores, of Bacillus anthracis, B. cereus, and B. subtilis on Stainless Steel Surfaces Coated with an Antimicrobial Silver- and Zinc-Containing Zeolite Formulation
Stainless steel surfaces coated with paints containing a silver- and zinc-containing zeolite (AgION antimicrobial) were assayed in comparison to uncoated stainless steel for antimicrobial activity against vegetative cells and spores of three Bacillus species, namely, B. anthracis Sterne, B. cereus T, and B. subtilis 168. Under the test conditions (25°C and

12. Fungistatic Performance of 10,10′-Oxybisphenoxarsine in Exterior Latex and Asphalt Coatings
10, 10′-Oxybisphenoxarsine has been found to be outstanding in its activity against bacteria and fungi. Parallel tests with known fungistats for comparison (2,3,4,6-tetrachlorophenol and phenylmercuric acetate) have demonstrated its superior activity and persistence in an exterior acrylate paint film and in an asphalt coating. In view of its superior antim
