Describing and modeling the release of an antimicrobial agent from an active PP/EVOH/PP package for salmon

Natural antimicrobial active packaging is an emerging technology for fresh fish preservation in which a chemical compound of natural origin is purposely incorporated into a packaging material to be released into the food surface in order to protect it from spoilage by foodborne microorganisms. The maximum efficiency of an antimicrobial package can only be obtained when an adequate activity is achieved immediately after the packaging operation and is maintained constant throughout the product’s shelf life. This work develops an active package designed for the preservation of fresh farmed salmon in cubes or slices, made up of a rigid polypropylene (PP)/ethylene–vinyl alcohol copolymer (EVOH)/PP tray heat-sealed with an active PP/EVOH/PP film lid in which 6.5% carvacrol is incorporated in the EVOH kernel as an antimicrobial active agent. The work also includes the measurement of the carvacrol kinetics and equilibrium parameters in the preserved salmon fillets, and proposes a mathematical model based on the finite element method to describe and simulate the common performance of the developed package/food system, and to predict its behavior under different working conditions or system configurations with the objective of finding the optimum combination of variables that ensure the best packaging performance. The results obtained from the determination of parameters showed a rapid migration of the active compound through the fish muscle, and a low affinity of the agent molecules for the food matrix. The active package was successfully developed, and the proposed model was satisfactorily used to detect the key factors that govern the package performance, and also to improve the package design by modifying the thickness distribution of the multilayer active film.     

食品包装视觉信息传达

为进一步形成科学的食品包装设计方法,为消费者提供更准确、快速的食品包装信息,文章通过整合国内外相关文献,综合分析了食品包装信息传达的三类关键线索：文字信息、食品意象和跨模态对应,指出文字信息在传达信息过程中更具优势,正面标语更具影响力,而其他详细信息会减少消费者认知偏差。文字更适合表达食品功能,而图片更适合表达感官诉求;其次,包装意象对消费者感知和反应的影响显著,视觉逼真度意味着更健康的选择;消费者对包装上食品的感知会影响其对包装内容物的评价,而跨模态对应研究是包装设计方法走向更科学、具体、精准的重要路径。

Critical review of controlled release packaging to improve food safety and quality

ABSTRACT

Controlled release packaging (CRP) is an innovative technology that uses the package to release active compounds in a controlled manner to improve safety and quality for a wide range of food products during storage. This paper provides a critical review of the uniqueness, design considerations, and research gaps of CRP, with a focus on the kinetics and mechanism of active compounds releasing from the package. Literature data and practical examples are presented to illustrate how CRP controls what active compounds to release, when and how to release, how much and how fast to release, in order to improve food safety and quality.

Ohmic Heating of an Electrically Conductive Food Package

Ohmic heating through an electrically conductive food package is a new approach to heat the food and its package as a whole after packing to avoid post‐process contamination and to serve consumer needs for convenience. This process has been successfully completed using polymer film integrated with an electrically conductive film to form a conductive package. Orange juice packed in the conductive package surrounded with a conductive medium was pasteurized in an ohmic heater. A mathematical model was developed to simulate the temperature distribution within the package and its surroundings. A 3‐D thermal‐electric model showed heating uniformity inside the food package while the hot zone appeared in the orange juice adjacent to the conductive film. The accuracy of the model was determined by comparing the experimental results with the simulated temperature and current drawn; the model showed good agreement between the actual and simulated results. An inoculated pack study using Escherichia coli O157:H7 indicated negative growth of viable microorganisms at the target and over target lethal process temperatures, whereas the microorganism was present in the under target temperature treatment. Consequently, our developed ohmic heating system with conductive packaging offers potential for producing safe food.

Shaping up: How package shape and consumer body conspire to affect food healthiness evaluation

Integrating research on human body shapes with studies of health cues in food package design, this research explores how food packages resembling humanoid shapes impact consumers’ evaluation of food healthiness. Adopting a self-referencing perspective, two studies show that packages resembling slim humanoid shapes lead to foods being evaluated as healthier, especially with female consumers whose bodily characteristics mark them as being not thin. Study 1 uses packages designed to mimic humanoid body shapes and shows that slimness effects depend on consumer gender and body mass index (BMI): The heuristic that slim packages contain more healthy foods is more pronounced with women and increasing BMI. Study 2 replicates these findings and offers process evidence for self-referencing as a mediator of the package slimness – healthiness evaluation. Together the findings highlight package shape as an important cue to food healthiness evaluation and aid marketers and designers in better matching packages to target audiences and products.
