the usage of antimicrobial materials for coating meat products, in addition to reducing the microbial population and increase of the quality safety of products, be greatly reduced usage of nitrites as preservatives and synthetic carcinogens. compounds that have antimicrobial activity can be mixed, stabilized or incorporated with edible coatings. spices and vegetable extracts are also a group of...

Cherry tomato is a nutritious, but highly perishable fruit. Peach gum polysaccharides (PGPs) can form edible films with antioxidant and antibacterial activities. The effects of PGP-based edible coatings on cherry tomatoes during hypothermic storage (4 °C) were investigated. PGP-based edible coatings effectively maintained firmness, decreased weight loss, inhibited respiration rate and delayed t...

combining antimicrobial agents directly into a food packaging is a form of active packaging. in this study chitosan-based edible films containing thyme and cinnamon essential oils at 0.5%, 1%, and 1.5% v/v were prepared to examine their antibacterial, physical and mechanical properties. scanning electron microscopy was carried out to explain structure-property relationships. films were more eff...

The incorporation of natural antioxidants into fi lms and edible coatings can modify their structure, improving their functionality and applicability in foods, such as in fresh-cut fruits. This paper reviews the more recent literature on the incorporation of antioxidants from several sources into fi lms and edible coatings, for application in fruits and vegetables. The use of synthetic antioxid...

Nowadays, the consumption of food products containing probiotics, has increased worldwide due to concerns regarding healthy diet and wellbeing. This trend has received a lot of attention from the food industries, aiming to produce novel probiotic foods, and from researchers, to improve the existing methodologies for probiotic delivery or to develop and investigate new possible applications. In ...

considering the potential benefits of edible coatings and films for storage of food materials, effect of edible calcium alginate film on shelf life of frozen lamb muscles was studied in the present research. microbial analyses including total microorganisms count and psychrophilic bacteria count and chemical analyses such as total volatile nitrogen (tvn) and moisture content determination were ...

UNLABELLED Chitosan is a biopolymer obtained by N-deacetylation of chitin, produced from shellfish waste, which may be employed to elaborate edible films or coatings to enhance shelf life of food products. This study was conducted to evaluate the effect of different concentrations of nanofiller (cellulose nanofibers, CNF) and plasticizer (glycerol) on tensile properties (tensile strength-TS, el...

Nowadays use of edible films and coatings is increasing due to their biodegradability properties. Fish gelatin obtained from fish skin wastes can be used as an appropriate protein compound for preparing the edible films. It can be also replaced pork gelatin. In this study, films were prepared from fish gelatin and phenolic compound caffeic in four levels of 0%, 1%, 3% and 5% at pH>10, temperatu...
