throughout the present, caseinate based edible films containing extracts of pomegranate peel were prepared in 3 levels of ×1, ×1.5 and ×2 (mic) and the physicomechanical, thermal, antimicrobial, and barrier properties of the films studied. to assess the microstructure changes resulting from the addition of the antimicrobial extracts, sem images were prepared from the surface and cross-section o...

it is possible to develop new biodegradable active packaging by coating biopolymers on paper-based packaging material and also incorporating proper antimicrobial agents into coating structure. in this study bacterial contamination of two commercial cardboard were evaluated.in order to manufacture an appropriate antibacterial packaging material, coating of chitosan-poly vinyl alcohol blends with...

BACKGROUND: Packaging is one of the important aspect of food quality and safety. Unfortunately, most of food packaging materials are from oil resources that are limited resources and undegradable. OBJECTIVES: The aim of this study was reaching an environmentally friendly packaging with enhancement safety of food. METHODS: After obtaining Bunium persicum (BP) and Mentha pepperita (MP) essential ...

71 samples of milk and dairy products were collected from 18 cities throughout iran. 93 strains of lactic acid bacteria (lab) were isolated and assayed against four opportunistic patho gens including e. coli, proteus and klebsiella as gram-negative and s. aureus as a gram-positive organism. all indicators (organisms) were hospital strains. among isolated bacteria, lactobacilli (37 isolates) had...

  Quinolone antibacterial agents are currently used for the treatment of various bacterial infections. The nature of functional group at the 7 position of the quinolone ring system is known to have strong influence on the spectrum and extent of in vitro antibacterial activity. Accordingly, a series of N-L2- oxo-2-(2- furyl) and N-[2- oxyimino (2- furyl) ethyl] piperazinyl quinolone derivatives...

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...

Alginate films with different degrees of crosslinking obtained by internal and external gelation method and alginate films incorporated with oregano essential oil were prepared. The effect of mechanism of gelation and the incorporation of oregano essential oil on their optical, mechanical, antibacterial, microstructural and water vapor barrier properties were evaluated. The films subjected to e...

Active edible films were prepared by adding carvacrol into sodium caseinate (SC) and calcium caseinate (CC) matrices plasticized with two different glycerol concentrations (25 and 35 wt%) prepared by solvent casting. Functional characterization of these bio-films was carried out by determination of some of their physico-chemical properties, such as colour, transparency, oxygen barrier, wettabil...
