The RN-820 Rice Freshness Analyzer or “Freshness Meister”, is a joint development between Kett and the Japan Grain Inspection Association. By placing Polished Rice in the measuring tray, adding colour with a pH indicator, then reading it in with a scanner and analyzing the image of each individual grain of Rice, it is possible to manage Rice freshness using images and numeric values. As quantification of the testing process is performed without relying on detecting colour differences with the naked eye, it is thus possible to completely standardize the freshness measurement. The test utilizes a pH indicator specified by the Japan Grain Inspection Association.
Applications: Polished Rice
Measurement method: Involves taking images of Polished Rice grains that have been coloured with a pH indicator, then image processing and determining their freshness using the dedicated software “Freshness Meister”.
