Aweta®, a trendsetter in technology of sorting fruit and vegetables by external

qualities, is now setting the pace for internal quality sorting. It is well accepted in the

industry that the internal characteristics of a piece of fruit ultimately drives consumer

satisfaction. Therefore a simple “good or bad” classification is not sufficient. A variable

scale to satisfy consumer preferences is needed.

AFS Acoustic Firmness Sensor The Aweta Acoustic Firmness Sensor (AFS) is the latest innovative technology

for on line non-destructive measurement of firmness and related characteristics.

Its excellent results are due to its ability to use acoustic signals that give an indication

of the firmness of the product as a whole, rather than only a small part.

How does the Acoustic Firmness Sensor work? The Aweta AFS gently taps the product and “listens” to the acoustic response.

The acoustic signal is analyzed and the ripeness and other quality aspects of the

product are determined. In this way it measures the vibration pattern of the entire

product. This pattern (resonance attenuated vibration) is characteristic of the overall

firmness, juice content, freshness and the internal structure of the product.

FI: Firmness indexThe signals are analyzed and translated into a firmness index (FI). The FI will be high

in fresh and juicy fruit and low in soft and ripe fruit. The FI gives a more accurate,

reliable, and consistent result, when compared to other destructive and non-destructive

methods, and is more in line with consumer preferences.

Destructive firmness tests (like the penetrometer) measure different properties than

non-destructive tests like AFS, therefore there is not always a good correlation

between these methods.

More effective than other methodsThe Aweta AFS gives consistent readings of the internal quality of a piece of

fruit, such as breakdown and dehydration, regardless of where the measurement

has been taken. Other methods may only take localized measurement and not

give a true overall reading of the internal quality of the product. To get a

firmness value of the product as a whole, some of these other methods must take

the calculated average of multiple separate measurements. These separate

measurements may vary, depending on where they are taken, and give

inconsistent and contradictory results.
