MIRASAL, a Device for Visualizing the Freshness of and Best Timing for Eating Food Animals
A device for evaluating the freshness of and the best timing for eating food animals to ensure safety and security
In collaboration with the National Institute of Advanced Industrial Science and Technology (AIST), we have developed a visualization device called MIRASAL to evaluate the freshness of and the best timing for eating food animals by using a simulation method to determine the concentration of degraded components in any part of a food animal (aquatic or livestock animal), which changes over the course of time after the animal has died.
Research
At the wholesale markets in fish and shellfish production and consumption areas, freshness is an important criterion in the determination of transaction prices, and the K value has been proposed as an evaluation index. However, since the K-value is calculated by sampling any part of a postmortem marine animal and analyzing the components after various pretreatments, real-time evaluation (understanding) at the distribution site is not possible. Aiming to solve this problem using an appropriate simulation method, we have developed a device that can evaluate the freshness and the best timing to eat fish and shellfish based on various information such as the type and size of the fish and shellfish, the elapsed time since death, and the storage temperature, using the method described above. We are currently working on the acquisition of the rights to the invention and for improvement of its portability (for use with smartphones, etc.). This device “MIRASAL” can also be applied to livestock animals such as beef, chicken, and pork.
