We are manufacturing, supplying and exporting Oil Spectrophotometer, which is used to measure metallic impurities. Many of the Metal ions promote auto-oxidation, which results in off-flavour accompanied by change in color. Studies have shown that Cu is most harmful metal in edible oils followed by Fe, Mn, Cr and Ni. To measure these ions costly analytical instruments are being used. The oil spectrophotometer developed at UEPL, in collaboration with CSIO, is based on Lambert-instrument consists of a light source, sample holder, detector and optical filters. Specific test reagents have been developed for the estimation of each metal ion. Concentration is directly displayed on LCD.
For Metallic ions in edible oils, water samples in :
