After its successful application on cherries and tomatoes, TR Turoni adapted its durometer on other fruits such as blueberries and grapes. "This instrument makes it possible to quickly, accurately and non-invasively measure the firmness of the pulp," said Enrico Turoni. "This is a very important ripening index, as it has a direct impact on the shelf life of the fruit.
On cherries, tomatoes, blueberries and grapes, the classical methods to assess the hardness of the fruit flesh, such as the penetrometer, do not give interesting results, according to Turoni. "With the durometer, however, we obtain a more realistic evaluation. The latter simulates the pressure of a finger on the flesh without piercing it. Its application to grapes can produce an index that can also be linked to the crunchiness of the fruit, which is highly appreciated by consumers".
“In addition to the sugar degree, a parameter traditionally measured on grapes, we can therefore quickly assess the firmness of the pulp and, thanks to the acidimeters that have been developed in recent years, we can also quickly ascertain the strength of acids".
TR Turoni also supplies an instrument to measure the effort required to remove the grape from the vine, a parameter increasingly requested by researchers and growers.
