Active Packaging Technologies with an Emphasis on Antimicrobial Packaging and its Applications
In response to the dynamic changes in current consumer demand and market trends, the area of
Active Packaging (AP) is becoming increasingly significant. Principal AP systems include those that involve
oxygen scavenging, moisture absorption and control, carbon dioxide and ethanol generation, and antimicrobial
(AM) migrating and nonmigrating systems. Of these active packaging systems, the AM version is of great importance.
This article reviews: (1) the different categories of AP concepts with particular regard to the activity of AM
packaging and its effects on food products, (2) the development of AM and AP materials, and (3) the current and
future applications of AM packaging
Bioactive Packaging Materials from Edible Chitosan Polymer—Antimicrobial Activity Assessment on Dairy-Related Contaminants
Quantitative PCR in Epidemiology for Early Detection of Visceral Leishmaniasis Cases in India
Inhibition of fungal plant pathogens by synergistic action of chito-oligosaccharides and commercially available fungicides
Chitosan is a linear heteropolymer consisting of β 1,4-linked N-acetyl-D-glucosamine (GlcNAc) and D-glucosamine (GlcN). We have compared the antifungal activity of chitosan with DPn (average degree of polymerization) 206 and FA (fraction of acetylation) 0.15 and of enzymatically produced chito-oligosaccharides (CHOS) of different DPn alone and in combination with commercially available synthetic fungicides, against Botrytis cinerea, the causative agent of gray mold in numerous fruit and vegetable crops. CHOS with DPn in the range of 15-40 had the greatest anti-fungal activity. The combination of CHOS and low dosages of synthetic fungicides showed synergistic effects on antifungal activity in both in vitro and in vivo assays. Our study shows that CHOS enhance the activity of commercially available fungicides. Thus, addition of CHOS, available as a nontoxic byproduct of the shellfish industry, may reduce the amounts of fungicides that are needed to control plant diseases
