Mapping of RFID tag readability in relation to the food content in a refrigerated sea container at 915 MHz

Perishable foods are extremely sensitive to temperature abuse often observed during sea transportation, which regularly involves long transit times. The goal of this study was to compare the effects of the cargo on RFID (radio frequency identification) tag readability to achieve real-time temperature monitoring. A 12 m long refrigerated sea container (68 m³) and a 915 MHz RFID system were used. The container was loaded three times with different food products: canned vegetables, fresh meat and frozen bread. Each load was instrumented with 42 RFID tags evenly distributed throughout the volume. Results showed that canned vegetables provide the best readings (97.6% of tags read), followed by fresh meat (61.9%) and frozen bread (57.1%) respectively. These results validated that radio waves at 915 MHz are absorbed by high water as well as ice contents. However, spacing between metal surfaces and tags can allow excellent RFID readability even if RF reflects on metallic surfaces.

Industrial relevance

The food industry is facing great challenges when it comes to food transportation and distribution. Marine transportation is a slow operation that can expose shipments to a significant range of non-ideal temperatures. Refrigeration units may experience failure during shipment, which inevitably causes losses in quality. The implementation of a real-time temperature monitoring system within a container can provide a good tool to address this issue. Radio frequency technology definitely offers additional benefits such as real-time monitoring as well as tracking and tracing.

Past, current and potential utilisation of active and intelligent packaging systems for meat and muscle-based products: A review

Interest in the use of active and intelligent packaging systems for meat and meat products has increased in recent years. Active packaging refers to the incorporation of additives into packaging systems with the aim of maintaining or extending meat product quality and shelf-life. Active packaging systems discussed include oxygen scavengers, carbon dioxide scavengers and emitters, moisture control agents and anti-microbial packaging technologies. Intelligent packaging systems are those that monitor the condition of packaged foods to give information regarding the quality of the packaged food during transport and storage. The potential of sensor technologies, indicators (including integrity, freshness and time-temperature (TTI) indicators) and radio frequency identification (RFID) are evaluated for potential use in meat and meat products. Recognition of the benefits of active and intelligent packaging technologies by the food industry, development of economically viable packaging systems and increased consumer acceptance is necessary for commercial realisation of these packaging technologies.

High pressure carbon dioxide inactivation of microorganisms in foods: the past, the present and the future

Thermal pasteurization is a well known and old technique for reducing the microbial count of foods. Traditional thermal processing, however, can destroy heat-sensitive nutrients and food product qualities such as flavor, color and texture. For more than 2 decades now, the use of high-pressure carbon dioxide (HPCD) has been proposed as an alternative cold pasteurization technique for foods. This method presents some fundamental advantages related to the mild conditions employed, particularly because it allows processing at much lower temperature than the ones used in thermal pasteurization. In spite of intensified research efforts the last couple of years, the HPCD preservation technique has not yet been implemented on a large scale by the food industry until now. This review presents a survey of published knowledge concerning the HPCD technique for microbial inactivation, and addresses issues of the technology such as the mechanism of carbon dioxide bactericidal action, the potential for inactivating vegetative cells and bacterial spores, and the regulatory hurdles which need to be overcome. In addition, the review also reflects on the opportunities and especially the current drawbacks of the HPCD technique for the food industry.

Food fraud: An exploratory study for measuring consumer perception towards mislabeled food products and influence on self-authentication intentions

The present study explores the concept of mistrust in country of origin information and the use of technology by consumers to corroborate information on food labels. Despite the plethora of food studies on trust conveyed by different sources, there appears to be a lack of studies exploring consumers' willingness to substantiate information on food labels, more specifically country of origin, and how it is influenced by mistrust. A self-administered survey was conducted in the city of Innsbruck, Austria, to evaluate the relationship between mistrust and the willingness to use technology and verify food label information in food stores. This present study suggests that mistrust towards industry and/or regulators in general augments consumers' willingness to self-authenticate. Findings also suggest that highly educated consumers are more likely to distrust the information on food labels, and are more willing to use a device to validate food label content. Expected results suggest that consumers who read labels on a regular basis expressed a higher willingness to self-authenticate, and that women are more likely to read labels than men. Limitations of the study are presented; theoretical significance and practical implications of the findings are also discussed.
