There is growing interest in food quality and safety, thus creating the demand for the development of highly sensitive devices to detect freshness and quality of perishable food. The development of on-package dual sensor and smart packaging systems is gaining momentum at the end of the supply chain management, regarding the quality of packed marine products. The colour change provides a clear indication of the quality to the consumers. Simultaneously, the manufacturers can track the quality of the packed marine products, at any point in time, to take an appropriate call depending on the quality. The on-package double sensors were built dependent on two pH pointers, and applied to screen the freshness of marine products. Methyl red (MR) and bromocresol purple (BCP) are commonly used pH indicators to detect the freshness of marine products. Once the marine products start spoiling, the MR changes from red to yellow, while the BCP changes from yellow to purple, based on the pH. Therefore, the label can be used as a simple and practical freshness indicator to continuously monitor and detect the quality of packaged products by data capturing, and also collecting it by cloud computing and the internet of thinking (IoT).
