New Israeli Application Determines Sweetness of Watermelons

Wouldn't it be nice to know just how sweet a watermelon tastes before cutting into the rind? Students at Israel's Haifa Technion University created a new phone application to help grocery shoppers determine the sweetness of a watermelon before purchasing! Writers at Yediot Achronot tell us more.

“We started looking for researchers with the view to finding a correlation between the external properties of a watermelon and its internal qualities,” explained Sarha’an. “Agricultural engineers said that there was no connection between the two but biologists sad that, in fact, there were.”

“We met with the researchers in Oxford and in MIT and came to the conclusion that the same factors which influence the fruit’s peel also influence the surface of a watermelon. So there is a correlation between external factors - tone, stripe patterns and the size of the circle at the bottom of the watermelon - and its content,” said Sarha’an…

"Since we developed the application, we have conducted experiments on 30 watermelons to teach the system about the content of the fruit. Since then, the system knows how to recognize and predict accurately the taste of every watermelon,” Sarha’an said excitedly…

Itai Davran, manager of the laboratory in which the project was developed said, “The cell phone goes round the watermelon, photographs it and examine specific parameters. In a short space of time, it provides results about the information that exist inside it. To the best of my understanding, the experiments were successful, and in my opinion this is the first time that a correlation has been identified between the shape and color, and the taste. I believe that this is probably going to succeed for other fruits too.”
