The researchers say that even within the same orchard, the fruit can ripen at different times because of the microclimate. The farmers can inspect the fruit and to make certain conclusions, but they run the risk of losing money.
To determine the ripeness of fruit can be on its smell. Peaches secrete molecules called volatile organic substances (VOC).
“We know that VOC vary in number and type depending on the different phases of fruit growth. Thus, electronic noses are a great solution because they allow for online monitoring of these molecules,” say the authors.
The researchers said their electronic nose has several advantages compared to existing approaches to determining maturity, including the fact that he analyzes in real time in an open environment and does not require direct handling of the fruit.
Although the study shows that E-nose has a high accuracy (over 98%), scientists continue to work on its components. They also consider the to create an electronic nose for wine.
