Olive oil is obtained from the fruit of the olive tree by manual or mechanical means. 
				                        The olive oil is a product, which is natural and
				 can be consumed as soon as the procedure of its collection has been 
				completed.
				                        
It is almost totally absorbed by the organism
				 (98%) and it gives the same number of calories as all the other natural
				 oils, which are 9.3 for each gram.
				                        It comprises the basic source of fats in Mediterranean Nutrition.
				                        
The fats of vegetable origin contain more 
				polyunsaturated and monounsaturated fat acids and are considered healthy
				 since they do not contain any cholesterol.
				                        
Different types of olive oil can be found 
				with more or less processing such as green olive oil, organic olive oil,
				 and aromatic olive oil.
Here are a few tips on how to savor the bold and subtle differences among the Tunisian olive oils.
				                
Examine the color. The two most important factors 
				influencing the color of the finished oil are the variety of olive and 
				its maturity at the time of harvest. Early-picked olives yield dark, 
				greener oil, while ripe olives produce an oil that is lighter and more 
				yellow in color.
Taste the oil either by dipping a piece of white 
				bread into it or by drawing a teaspoonful of oil quickly into the mouth,
				 mixing it with air to register the sensation of all the nuances of 
				flavor. Between sips, cleanse the palate with a piece of crisp apple, 
				fresh sliced fennel or unflavored sparkling water.

				conditions, particularly thermal conditions, that do not lead to oil

				washing, decantation, centrifugation and filtration.
 
				                They are graded according to their organoleptic and chemical characteristics into the following categories:
Extra virgin olive oil :  virgin olive oil with free 
				acidity, expressed as oleic acid, of no more than 0,8g per 100g and the 
				organoleptic characteristics specified for this category in the IOC

Virgin olive oil :  virgin olive oil 
				with free acidity, expressed as oleic acid, of no more than 2g per 100g

				or other physical treatments, to the exclusion of oil obtained by

				 Olive-pomace oil is a blend of refined olive-pomace oil and virgin
