Determination of fish quality parameters with low cost electronic nose

Abstract

In the present study, the odour changes of trout, sea bream and sea bass were measured and recorded with Arduino microprocessor compatible MQ3, MQ4, MQ5, MQ8, MQ9 and MQ135 sensors during a week of storage. The odour intensity measured by the sensors were compared with the microbiological and sensory data, and spoilage thresholds were obtained. An electronic nose box was developed, which could quickly detect the quality of 10 g of fish meat placed inside using an Arduino microprocessor. Total viable counts of all test samples defined by the developed box as "Fresh Fish" were found to be were found to be lower than the level of 3 log CFU/g. The results of the study demonstrated that the odour sensors controlled by Arduino microprocessor could be fast, easy and low-cost solutions for determining the food quality parameters.
