The anthocyanin content in different colored rice was determined by pH differential method. The results indicated that the highest anthocyanin content variety is P1 as 0.632 mg/g, the lowest anthocyanin content is P18 as 0.049 mg/g, the others are between them. Effects of illumination and temperature on the stability of pigment in different colored rice was determined by colorimetry. The stability of pigment in P4、P8 is relatively good, and the stability of pigment in P16、P17 is relatively poor. Finally, we screened out high pigment content and good stability quality colored rice varieties is P4 by using PCA based on SPSS.
