Abstract: The present invention relates to a method for preparing lycopene crystals with high purity and low harm. The method comprises the following steps: (1) mixing lycopene oleoresin with a mixed solvent consisting of an alkane and a lower alcohol, and heating and stirring the resultant for dissolution to form a homogenous solution; (2) cooling the homogenous solution for crystallization, filtering the resultant to obtain a filter cake; and (3) washing the filter cake successively using a lower alcohol and an alkane, and drying the resultant to obtain lycopene crystals. According to the method provided by the present invention, lycopene crystals can be obtained using a mixed solvent by means of one step crystallization, and the crystal content is further improved and harmful substances in the crystals are reduced by means of a two-step crystal washing process to obtain lycopene crystals with high purity and low harm.
