C. Nergiz, THE EFFECT OF REFINING PROCESSES ON THE TOTAL POLYPHENOL AND 1,2-DIPHENOL CONTENT OF OLIVE OIL, International journal of food science & technology, 28(5), 1993, pp. 461-464
The effect of commerical olive oil refining processes on the total pol
yphenol and 1,2-diphenol content of the oil was investigated. The mean
losses of total polyphenols and 1,2-diphenols of the crude oils were
84-87% and 79-88% respectively. There was no difference between the ch
emical and physical refining processes in reducing phenols in the oil
samples.
