In oil milling, in order to obtain high-quality oils without reducing the industrial yield, to the use of coadjuvants with a physical action and adequate operating conditions is necessary. The aim of this study was to evaluate the influence of talc addition during the malaxation stage in an oil mill on the resulting oil. Moreover, the oil obtained by talc treatment can be classified as extra virgin olive oil as this coadjuvant has a physical action. Talc increases the extraction efficacy by up to 2.35%, but retains 26.2% of its weight in oil; therefore, it is disadvantageous to use a dose higher than 0.75%. The volatile compound contents were increased in trials using lower doses of talc. In contrast, the quantity of the phenolic compounds was increased in trials using higher talc doses. In low doses, talc does not influence the content of antioxidants and volatile compounds.

在油研磨中，为了在不降低工业产量的情况下获得高质量的油，必须使用具有物理作用和适当操作条件的助剂。这项研究的目的是评估在油磨机的错误处理阶段添加滑石粉对所得油的影响。此外，通过滑石处理获得的油可以归类为特级初榨橄榄油，因为该助剂具有物理作用。滑石粉可将提取效率提高多达2.35％，但在油中保留其重量的26.2％。因此，使用高于0.75％的剂量是不利的。在试验中使用较低剂量的滑石粉增加了挥发性化合物的含量。相反，在使用较高滑石剂量的试验中，酚类化合物的量增加了。低剂量时
