DESCRIPTION
March 13, 2008 - Presentation at the Libyan Ministry of Agriculture of CDR testing systems for olive oil: OxiTester and Minifood.TRANSCRIPT
Olive Oil
The Mediterranean Golden Oil
Source: Official Journal of the European Union
The Acidity or FFA (Free Fatty Acid)
is the first and essential indicator
of the quality of the olive oil
The Peroxide value (or index) is
the indication of primary oxidation and the first step to rancidity of the olive oil.
The peroxides are incresed by high temperatures and by the exposure to light and oxygen
Low peroxides=
High quality and better preservation
The antioxidant power of polyphenols has an important role for the stability and the shelf life
The polyphenols are determined by cultivar, harvest period and the extraction process
High polyphenols=
High quality and long life
“the indication ‘cold extraction’ may appear only for virgin or extra virgin olive oils obtained at a temperature below 27 °C by percolation or
centrifugation of the olive paste”

Temperature control in a maximum of 4 oil mill areas with 4 probes.
Temperature values stored over intervals of time ranging from 2 to 12 hours.
Printout of highest temperature on the slip issued by OxiTester.
It can be used with PrintManager software to print and save the charts related to the measured temperatures. Important for traceability.
Software for connection Oxitester / Computerto store and print:
• Information of the oil sample and mill
• Results of analysis
• Temperature detected by the probes, if connected
important information for traceability
Click on “Temperature”:the screen shows the values of the recorded temperatures and the graphic trends.
Press and digital centrifuge to extract a small sample of oil
from olives.
The system is designed to take small samples that are sufficient to be tested with CDR's OxiTester analyzer to:
• better determinate the best period of harvest by analyzing the olive samples in order to evaluate the maturity degree
• optimize the oil extraction process. In fact, comparing the analytical values obtained on the oil extracted with the CDR system and those obtained with the processing plant it is possible to verify, control and improve the extraction process
• separate the olive batches according to their quality
Oxitester has been developed, designed and manufactured by CDR Srl
