The presence of free fatty acids in olive oil is caused by a reaction started when lipolytic enzymes (that are normally present in the pulp and seed cells of the olive) come in contact with the oil (that is contained in particular vacuoles) due to loss of integrity of the olive. [3] High values of free acidity in olive oil can be due to ...
Virgin olive oil is a lesser grade of virgin oil, with free acidity of up to 2.0%, and is judged to have a good taste, but may include some sensory defects. Refined olive oil is virgin oil that has been refined using charcoal and other chemical and physical filters, methods which do not alter the glyceridic structure. It has a free acidity ...
Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]
Compared to the many oils used for frying (like canola oil or vegetable oil), olive oil has a lower smoke point (around 375 degrees), but that doesn't mean you can't cook with it!
The acid number for an oil sample is indicative of the age of the oil and can be used to determine when the oil must be changed. [5] A liquid fat sample combined with neutralized 95% ethanol is titrated with standardized sodium hydroxide of 0.1 eq/L normality to a phenolphthalein endpoint. The volume and normality of the sodium hydroxide are ...
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
The more FFA an oil contains, the quicker it will break down and start smoking. [2] [3] The lower the value of FFA, the higher the smoke point. [4] However, the FFA content typically represents less than 1% of the total oil and consequently renders smoke point a poor indicator of the capacity of a fat or oil to withstand heat. [4] [5] [6]
