Olive oil containing food composition
A method has been found for the manufacture of a spread which is characterized by the presence of a substantial amount of olive oil polyphenols and the absence of olive oil odour. The deodorized olive oil to be used for the preparation is obtained by a mild refining process which spares the olive oil's minor components.
1. A process for refining an olive oil which process comprises sparging the oil with an inert gas at a temperature of up to 250° C. under such conditions of sparging gas flow, pressure and process time that the refined oil is free from olive oil odour and contains at least 1500 ppm squalene, the refining conditions being such that at least 60 wt % of the polyphenols present in the source oil are retained.
2. A process according to claim 1 where the olive oil to be refined, the source oil, contains at least 100 ppm of polyphenols.
3. A process according to claim 1 where the sparging temperature is 120-250° C.
4. A process according to claim 1 where the sparing pressure is 2-5 mbar.
5. A process for the manufacture of a food composition which contains 0.1-90 wt. % of olive oil, comprising the steps of
1. selecting the ingredients usual for the composition, including an olive oil source, and
2. employing the processing steps usual for obtaining the composition,
where 10-100 wt % of the selected olive oil has been obtained according to claim 1 .
6. A process for refining an olive oil which process comprises sparging the oil with an inert gas at a temperature of up to 250° C. under such conditions of sparging gas flow, pressure and process time that the refined oil is free from olive oil odour and contains at least 1500 ppm squalene, the olive oil to be refined, the source oil, containing at least 100 ppm polyphenols.
