Digital oil spectrophotometer has been designed for the edible oil industry to measure metallic impurities of copper, nickel, ferrous and phosphate in ppm level in the edible oils like coconut oil, groundnut oil, sunflower oil, soyabean oil, mustard oil and other similar edible oils. This instrument has been designed and manufactured in technical collaboration with the central scientific instruments organisation, chandigarh under the technology modernization and upgradation mission for oil and pulses industry launched by the ministry of agriculture, government of india, new delhi.
Oils and fats obtain metal contents from soils where the plants are grown and later from contact equipment during crushing and storage. Many of the metal ions promote autoxidation that results in off – flavour and odour accompanied by colour development. Studies have identified copper as the most harmful metal followed by fe, mn, cr, ni, concentration of these ions vary from 0.1 to 2.0 ppm. To measure these ions costly analytical instruments are being used.
Csio has developed an integrated system along with test reagents ti measure metallic impurities cu, ni & fe and phosphate – p in ppm level. This is a portable, low cost instrument in which results of concentration are directly displayed on lcd. The developed stable reagents eliminate cumbersome colour development procedures.
