REGENERATING AGENT FOR DEGRADED EDIBLE OILS

摘要

[Problem] To provide a magnesium-silicate-containing regenerating agent for degraded edible oils, which has both good deoxidizing capability and good decoloring capability. [Solution] The present invention relates to a regenerating agent for degraded edible oils, which contains magnesium silicate and is characterized in that (1) the magnesium silicate is a crystal system of a tri-octahedral smectite clay mineral, (2) the magnesium silicate has a ratio of the integral intensity (Ib) at a peak appearing at 2? = 26-28° to the integral intensity (Ia) at a peak appearing at 2? = 18-20° (i.e., Ib/Ia) of 1-2 in an X-ray diffraction measurement, and (3) the magnesium silicate has a SiO2/MgO ratio (X) of 1.2-3.8 by mole.
