Understanding the Physical Changes in Olive Oil

The Process of Crystallization
As the temperature drops, the impregnate fats - which have higher melting points - begin to turn into solid first. This creates a cloudy, waxy, or grainy appearance that often alarms consumers who vex their oil has locomote rancid. This process is whole natural and is a sign of honor rather than spoil. If you see white blob or a thick, semi-solid texture, your oil is simply reacting to the frigidity.
Is the Flavor Compromised?
The chemical construction of the fat acids remains inviolate during freeze. Unlike sure emulsion or dairy production that might separate or lose their texture permanently, olive oil is robust. Formerly the bottleful return to room temperature, the crystal will mellow, and the oil will revert to its open, gilt, or greenish liquidity province.
