The effects of silica gel, a substance commonly used for fractionation of essential oils during preparation, were investigated on cold-pressed peel oil of yuzu (C. junos), a sour Citrus fruit. The silica gel treatment was performed for 24 h at 20, 5 and -21 degrees C. The volatile components were determined using GC and GC-MS. Important compositional changes occurred at 20 and 5 degrees C and minimally or virtually absent at -21 degrees C.
