GREENTEST:A scientific approach to food safety
Greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested. Lower resistance = higher nitrate content
The presence of nitrate ions in organic matter measurably increases conductivity. This measurement differs according to the ion concentration and cell structure of the fruit or vegetable under test.
Calibrated through extensive testing
Our scientists developed the Greentest nitrate content protocols by using a mass spectrometer to determine nitrate levels in a large number of fruit and vegetable specimens.
Testing a range of specimens under laboratory conditions allowed us to establish normative levels for various fruit and vegetable species.
A high degree of accuracy
The results were applied to test algorithms which have been coded into the Greentest device. The device has been extensively back-checked against specimens that were subsequently tested with a mass spectrometer.
