چکیده مقاله:
Background: Fish is a food ingredient that is consumed throughout the world. When fishes die,
their freshness begins to decrease. The freshness of the fish can be determined by the aroma it
produces. The purpose of this study is to monitor the odor of fish using a collection of gas sensors
that can detect distinct odors. Methods: The sensor was tested with three kinds of samples, namely
Pseudomonas aeruginosa, tuna, and tuna that was contaminated with P. aeruginosa bacteria. During
the process of collecting sensor data, all samples were placed in a vacuum so that the gas or aroma
produced was not contaminated with other aromas. Eight sensors were used which were designed
and implemented in an electronic nose (E‑nose) device that can withstand aroma. The data collection
process was carried out for ۴۸ h, with an interval of ۶ h for each data collection. Data processing was
performed by using the principal component analysis and support vector machine (SVM) methods to
obtain a plot score visualization and classification and to determine the aroma pattern of the fish.
Results: The results of this study indicate that the E‑nose system is able to smell fish based on the
hour with ۹۵% of the cumulative variance of the main component in the classification test between
fresh tuna and tuna fish contaminated with P. aeruginosa. Conclusion: The SVM classifier was able
to classify the healthy and unhealthy fish with an accuracy of ۹۹%. The sensors that provided the
highest response are the TGS ۸۲۵ and TGS ۸۲۶ sensors.
