Kind of oil: Olive oil, sunflower oil, palm oil. Most commonly used is the oil extracted olives from.Olive’s oil , it’s coming pressing olive from.Pomace oil , from pomace of olives by treatment of chemical extraction, and other physical processes.They have different characteristics. And physical-chemical properties.By analysis of purity and quality, it’s possible to know that

Criteria of quality: Oil’s composition through gas-chromatography

Criteria of purity : organoleptic characteristics( such as smell, color, look 1)acid composition: quality criteria has been different parameter ACIDITY Show acidity of oil, best is from 0,1 to 0,2. if is more high oil is not good. 2)number of peroxide : Into oil’s molecule there are links oxygen with double bonds who aren’t Stable, this is the reason because the oil can’t be to contact of air.Number of peroxide must be from 15 to 20.

Criteria of purity : 3)wax: Wax is into olives,it’ll has small amount in oil obtained pressin olives from. 4)spectrophometric u.v.: This analisys show double and triple bonds. High value mens oil is old. 5)purity criteria: sensory statement of value has based on characteristic flavor.
