“…Various compositions of LDPE, glucose oxidase, and catalase were produced in Tetra Pak's pilot plant, and showed up to 97% activity could initially be achieved even after exposure to 325 °C during production. Control of production parameters was key to maintaining the package's oxygen scavenging capability [104]. Johansson et al worked to improve embedding the glucose oxidase and catalase oxygen scavenging pair by varying combinations of LDPE, polypropylene, and polylactic acid [55].…”

Active food packaging involves the packaging of foods with materials that provide an enhanced functionality, such as antimicrobial, antioxidant or biocatalytic functions. This can be achieved through the incorporation of active compounds into the matrix of the commonly used packaging materials, or by the application of coatings with the corresponding functionality through surface modification. The latter option offers the advantage of preserving the packaging materials' bulk properties nearly intact. Herein, different coating technologies like embedding for controlled release, immobilization, layer-by-layer deposition, and photografting are explained and their potential application for active food packaging is explored and discussed.

The incorporation of active oxygen scavengers in polymer packaging materials is essential to allow packaging of oxidation sensitive products. Opposed to the currently available chemical oxygen scavengers, systems based upon natural and biological components could have advantages towards consumer perception and sustainability. A modelsystem for a new oxygen scavenging poly(ethylene terephthalate) (PET) bottle is proposed using an endospore-forming bacteria genus Bacillus amyloliquefaciens as the active ingredient. Spores were incorporated in poly(ethylene terephthalate, 1,4-cyclohexane dimethanol) (PETG), an amorphous PET copolymer having a considerable lower processing temperature and higher moisture absorption compared to PET. To asses spore viability after incorporation, a method was optimized to extract spores from PETG using a chloroform/water mixture. Samples were also analyzed using a Live/Dead BacLight Bacterial Viability kit. It was shown that endospores were able to survive incorporation in PETG at 210°C. Incorporated spores could actively consume oxygen for minimum 15 days, after an activation period of 1-2 days at 30°C under high humidity conditions. Industrial relevance: The study describes a modelsystem for the use of incorporated spores genus Bacillus amyloliquefaciens as an active oxygen scavenger in PET multilayer bottles using PETG as the middle layer material. Industrially, oxygen scavengers using incorporated viable spores as the active compound could have advantages towards consumer perception, recyclability, safety, material compatibility, production costs, … compared to currently available chemical oxygen scavengers.

Enzyme immobilization in latex dispersion coatings for active food packaging

et al. 2007

View full text Add to dashboard Cite

Carboxylated styrene acrylate latex samples have been functionalized by the immobilization and entrapment of the enzyme glucose oxidase (GOx), which can be used as an oxygen scavenger in food packaging. GOx was covalently immobilized both on the surface of already formed fi lms and on the latex particles in dispersion, as well as entrapped within the polymer matrix. In the latter two cases, polymer fi lms were formed after the enzyme had been added to the latex dispersion. The storage stability of the enzyme and the infl uence of adding clay were also studied. For a given amount of enzyme, the enzyme immobilized on the fi lm surface showed an enzyme activity about 10 times higher than that of the enzyme present within the polymer matrix. This is probably due to the diffusion limitations of the substrate in the polymer matrix. The fi lms with the enzyme present within the polymer matrix, however, showed a higher total oxygen-removal capacity than fi lms with the enzyme immobilized on the surface. Entrapped enzyme showed a slightly higher activity than enzyme immobilized in the dispersion due to the negative effect of the activating chemicals used during the immobilization and on conformational constraints upon covalent bonding. Low amounts of clay added to the dispersion decreased the enzyme activity, but with higher amounts of clay the enzyme activity increased, probably because of the increased porosity and thus higher substrate accessibility. The most suitable storage condition for all the enzyme-containing fi lms was +8°C, which is just above the glass transition temperature of the polymer used.
