1.4678 1.4720 1.4687 Critical temperature of dissolution or Valenta number 69.2" 83'.4O 72.0" Olive Oil. Rapeseed Oil. (76 Olive 4-26 Rape).

The above results show how closely this mixture of olive and rapeseed oils approaches the constants of a pure olive oil. It will also be noted that figures are stated for the critical temperature of dissolution or Valenta number. In the experience of this laboratory, the Valenta number is the most satisfactory means of detecting this particular adulterant. The details of this test are herewith abstracted from "The Technical Handbook of Oils, Fats and Waxes," Percival J.
