The amount of water dissolved in safflower oil at the frying temperature (180°C) was 5181012ppm, allowing water to drop continuously (0.035g/2min) into the oil for 13h.<BR>When the oil was heated with metal plates under the same conditions, the amount of dissolved water in the oil increased more than in the absence of the metal plates. In case of stainless steel, the amount was 1.26 to 1.33 times, and with aluminum plates, 1.06 to 1.13 times the amount without plates.<BR>When these metal plates were heated with the oil under the above conditions, the water dissolved the metal of the plates into the oil. In case of stainless steel, iron dissolved from 0.17 to 0.77ppm, nickel, 0.04ppm and chromium, from 0.02 to 0.03ppm. Similarly, the amount of aluminum dissolved from the aluminum plate was from 0.10 to 0.45ppm.
