Automatic starchmeter
for controlling the ripeness of apples and pears

The AMILON is an automatic starchmeter

The AMILON is an automatic starchmeter that photographs an equatorial section of fruits that have been previously exposed to an iodine-potassium iodide solution. Innovative software processes the image and expresses a precise measurement of the starch stage.
This instrument is particularly suitable for all cases in which it is necessary to determine the index of ripeness in apples and pears with a quick measurement that is accurate and immune from erroneous interpretation.


Objective and automated measurement of starch hydrolysis (starch stage), a universally used assay as an index of ripeness in apples and pears; reproducible instrumental measurement immune from
erroneous interpretation of the visual reading; quick measurement on single piece and/or sample of max 12 pieces; measurement feasible for all variants without having to refer to specific figures.

Operation principles

The starch stage is highlighted through reaction with an iodine-potassium iodide solution. The equatorial section of the fruit thus treated is photographed, then the image is processed and the starch value is computed and displayed, for each single piece and as an average over the sample (max 12 pieces). The starch value can be displayed in accordance with commonly used reference scales of 1÷10 (internationally recommended), 1÷5, 1÷8 or 1÷1000.
