Palm oil has the following features:
1. Contain more unsaturated fatty acid, good stability, not easy to occur the oxidation.
2. The palm oil contains rich vitamin A in the original (500-700 parts per million (PPM) and vitamin E (500-800 parts per million (PPM).
3. To determine the existence of palm oil can't use color reaction. It is difficult to use simple method to measure out the palm oil which mixed with Hydrogenated oil .
Palm oil or hydrogenated palm oil
It will have a light smell which similar with violets after oxidize moderately.And it can be said qualitatively that palm oil exists if we can smell the semll during the test of stability or accelerated oxidation test.
According to the actual production experience, crude palm oil deodorization temperature is generally between 256-265 degrees, if too low,it will do bad to the FFA extraction and decompose the colour and lustre; and it will increase the cost and trans fatty acids if the temperature is too high..
