From Fundamentals to Applications: Understanding BPA-Non-Intent Resin Technology in Food Contact Metal Packaging Coatings

Open can of mandarins in light syrup.
Consumer and regulatory pressure to replace bisphenol-A (BPA)-based materials in food contact metal packaging coatings has increased in recent years. Regardless of the controversy around BPA, consumers expect canned foods to be free of substances perceived to have negative health impacts while maintaining current shelf life and flavor characteristics. To address the market needs, formulators must innovate to deliver BPA-non-intent...

The antimicrobial properties of two disparate bio-based coating additives were evaluated in a polyvinyl alcohol (PVA) food packaging coating for antimicrobial activity. Chitosan, a shrimp and crustacean shell derived polysaccharide, and an antimicrobial peptide were evaluated in a dissolvable food package coating for reductions in microbial growth after contacting agar patties serving as food simulants. Where the antimicrobial components of...

Getting the Good Word Out About Microbial Control Technologies

Bacterial cell or virus, 3d generated view from microscope.
Without the use of microbial control technologies, the performance of many types of products and processes would be highly diminished. Despite their essential role in preventing microbial contamination and its potential impacts, which range from product degradation and damage to potential harm to public health, few consumers and even many people within industry have little knowledge or understanding of their...

Proteins and Peptides as Replacements for Traditional Organic Preservatives: Part I

Protein molecules
The utility of a high-throughput, spectrophotometric assay in screening over 23 enzyme and peptide-based additives against bacterial coating spoilage agents was evaluated. Candidate additives were then evaluated using ASTM D2574 for in-can coating spoilage challenges, and additives that may be used to substitute for traditional biocides were identified that eliminated recoverable bacterial growth.

The efficacy of the active biocide ingredients used in antifouling bottom paint to contain and impede the growth of biofouling on boat hulls is of global economic concern, given that costs associated with mitigating the damage caused by invasive species are escalating, especially in coastal waters where fouling nutrients are concentrated. The efficacy of an antifouling coating depends on site-specific...
