What is the Reichert Meissl value of oil?
The Reichert value is an indicator of how much volatile fatty acid can be extracted from fat through saponification. It is equal to the number of ml of 0.1 normal hydroxide solution necessary for the neutralization of the water-soluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.

What is RM in pure ghee?
Reichert Meissl (RM) value is substantially a measure of the. lower chain fatty acids of ghee i.e. butyric (4:0) and caproic. (6:0). The value of milk fat ranges from 17-35, which is well. above all other fats and oils.
Why we check RM value of ghee?
These values were within the range of the standard RM value for pure ghee (Table 2). RM value indicates whether the ghee is prepared from milk fat or not [15]. It can be said that the branded industries tried to make ghee from milk fat. Local samples’ RM value varied significantly.
