Problems solved by technology

Coating packaging surfaces with antimicrobials is also ineffective as such coatings are often water-based and can therefore drip off the food surface and collect in recesses in the packaging
Finally, immobilizing the antimicrobial on the packaging substrate inherently reduces the flow of the antimicrobial and affects efficacy

example 1

[0070] Chicken skin samples were inoculated with Escherichia coli 11303 and covered with a piece of polyethylene film (DOWLEX TM 2045G) processing:

[0071] ● Control: Polyethylene film without active antimicrobial agent ("control");

[0072] ● Corona: Corona treated and treated with 2% active antimicrobial agent (cetylpyridinium chloride ("CPC"), N α - Lauroyl-L-arginine ethyl ester ("LEA"), or dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (a quaternary silane compound) ( "SQ"), as described below) soak overnight polyethylene film (DOWLEX TM 2045G)("corona CPC", "corona LEA", "corona SQ");

[0073] ● water: 1 ml of aqueous solution (as shown below) with 2% active antimicrobial agent was sprinkled on the surface of the chicken, and polyethylene film (DOWLEX TM 2045 G) placed on the treatment (“CPC Water”, “LEA Water” and “SQ Water”); and

[0074] ● Polymer (antimicrobial composition): A 1 ml solution (prepared as described above) containing 2% by w...

example 2

[0080] The method described in Example 1 was further used to assess the effect of instillation on antimicrobial activity. Chicken skin samples inoculated with E. coli were treated using the three treatment techniques described in Example 1 (corona (in figure 2 called "corona film"), water (in figure 2 referred to as "CPC-water") and polymers (antimicrobial compositions) (in figure 2 , referred to as "CPC-polymer" and prepared as described in Example 1) was treated with CPC. One set of chicken skin samples was kept flat during overnight storage, and the other set was stored vertically (upright) during overnight storage to induce instillation. image 3 Shows the observed reduction in bacterial levels. The samples treated with the corona-treated film ("corona film") showed little reduction in bacteria, while the polymer (antimicrobial composition) treatment technology ("CPC-polymer") samples showed little reduction in both sample groups All showed a significant reduction i...

example 3

[0082] This example evaluates the effect of viscosity of an antimicrobial composition on antimicrobial efficacy. Each treatment technique was evaluated as described in the "Efficacy Testing" section above. A control sample contained no rheology modifier and no active antimicrobial ("control"). Includes CPC and a range of rheology modifier levels (a methylcellulose, available in METHOCEL TM An antimicrobial composition of E50 (commercially available from The Dow Chemical Company) was compared with an aqueous solution of CPC. image 3 Each result is displayed. An aqueous solution of CPC ("2% aqueous CPC") did not result in a significant reduction in bacteria. Similarly, with 0.5% rheology modifier ("2% CPC; 0.5% polymer"), 1% rheology modifier ("2% CPC; 1% polymer") and 2% rheology modifier ("2% CPC; 2% polymer") solutions (viscosity about 74 cP) also did not show significant reduction in bacteria. A solution at 4% rheology modifier ("2% CPC; 4% polymer") (viscosity about 7...

Abstract

Materials are provided that combine certain antimicrobial compositions with substrates to provide materials suitable for the packaging of food products, such as meat products. In one aspect, the present invention provides a material suitable for packaging that comprises (a) a substrate, and (b) an antimicrobial composition comprising: (i) an active antimicrobial agent and (ii) a carrier, wherein the antimicrobial composition has a viscosity of at least 50 centipoise at temperatures between 2 DEG C and 12 DEG C.

Description

technical field [0001] The present invention relates to materials useful for packaging comprising antimicrobial compositions. Such materials are particularly useful in food packaging applications. Background technique [0002] In the packaged food industry, particularly in packaging fresh meat into plastic materials, protecting the meat from bacteria and bacterial growth is important to meat processors, packers and retailers. In the fresh meat space, both cost-effectiveness and long-lasting antimicrobial efficacy are important considerations. The vast majority of commercial antimicrobial technologies in the fresh beef, pork, and poultry markets are body applications that utilize antimicrobial sprays or baths to apply antimicrobial agents to animal carcasses. [0003] It is desirable to provide multiple pathogen barriers along the supply chain in the preparation and packaging of fresh meat. As such, a great deal of research has gone into developing antimicrobial solutions ...
