Ten-degree palm oil was produced by fractionation and physically refination to reach the product quality requirements. But the frost resistance of refined ten degree palm oil was worse, thus affecting product transparency. In order to reduce the effect of physical refined conditions on the frost resistance of refined ten degree palm oil, turbid phenomenon at 20 ℃ was used as a judicial indicator and the effects of deodorized temperature, deodorized time, bleached time and activated clay loading were investigated. The results showed that deodorized temperature, deodorized time and activated clay loading had effects on the frost resistance of refined ten degree palm oil, while bleached time had little effect on it. By comparing the frost resistance, iodine value, trans fatty acids of unrefined and refined ten degree palm oil，the optimal physical refined conditions were determined as follows: bleached time 20 min, activated clay loading 1%, deodorized temperature 230 ℃ and deodorized time 2 h.
