Allergy information on food labels is crucial to individuals with food allergies. The purpose of this paper is to investigate what information consumers are concerned with as well as improving the allergen information on the product labels.
A questionnaire was developed based on previous studies and was administered to citizens in South Korea. Descriptive analysis and analysis of variance were conducted to find significances of important information when purchasing and improvement needed on the labels in relation to allergy knowledge.
The results indicated that respondents were concerned about allergy information and general information regarding the basic value of food and also food safety. In addition, this study found knowledge of food allergies is not related to consideration of allergy information on labels.
This study measured consumers’ perceptions of the current food allergy labeling when purchasing food products. This study concluded improvements were needed in order to deliver allergy information in a clear manner. Such as font size, shape, and color should be implemented together in order to communicate effectively with allergic consumers.

Design, fabricate and evaluate all-solid-state wearable sensor systems that can monitor ion concentrations in human sweat to provide real time health analysis and disease diagnosis capabilities.
A human health monitoring system includes disposable customized flexible electrode array and a compact signal transmission-processing electronic unit.
Patterned rGO (reduced-graphene oxide) layers can replace traditional metal electrodes for the fabrication of free-standing all solid film sensors to provide improved flexibility, sensitivity, selectivity, and stability in ion concentration monitoring. Electrochemical measurements show the open circuit potential of current selective electrodes exhibit near Nernst responses versus Na+ and K+ ion concentration in sweat. These signals show great stability during a typical measurement period of 3 weeks. Sensor performances evaluated through real time measurements on human subjects show strong correlations between subject activity and sweating levels, confirming high degree of robustness, sensitivity, reliability and practicality of current sensor systems.
In improving flexibility, stability and interfacial coherency of chemical sensor arrays, rGO films have been the developed as a high-performance alternative to conventional electrode with significant cost and processing complexity reduction. rGO supported solid state electrode arrays have been found to have linear potential response versus ion concentration, suitable for electrochemical sensing applications. Current sweat sensor system has a high degree of integration, including electrode arrays, signal processing circuits, and data visualization interfaces.
