Rice Freshness Analyzer
RN-820

The "Freshness Meister" is a joint development between Kett and the Japan Grain Inspection Association. By placing polished rice in the measuring tray, adding color with a pH indicator, then reading in with a scanner and analyzing the image of each individual grain of rice, it is possible to manage rice freshness using images and numerical values. Since it is possible to quantify the testing process without relying on detecting color differences with the naked eye, it is thus possible to completely standardize the freshness measurement. The test utilizes pH indicator specified by the Japan Grain Inspection Association.
