PALM OIL AND PALM KERNEL OIL

Adulteration of palm oil with palm stearin can be recognized by examining the ratio of the triglycerides PPP to MOP, which lies in pure palm oil between 3.5 and 4.5 and is elevated in the case of adulteration. The content of palmitic acid and the solid fat content are additional indications. Adulteration of coconut and palm kernel oils with palm kernel olein is best recognized by measuring the iodine number (which is max. 11 for coconut oil and 19 for palm kernel oil) and also by the content of stearic, oleic and linoleic acids, the sum of which should not exceed 11.5% for coconut oil and 22% for palm kernel oil respectively. The content of triglycerides with carbon number 46 to 54 may additionally be used.
