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. The method is fast and convenient, lycopene crystals with high purity, low harm, and sanitary safety can be produced, and the method is suitable for industrial production.
