Abstract

Crystallization behavior of palm kernel oil under different cooling rates were contrastively analyzed using In-situ analysis devices of PVM and FBRM, the crystallization products were detected by XRD, polarizing microscope and DSC. The results enriched the data of oil suspension crystallization process. Palm kernel oilcrystals show different morphologies under different cooling rates. When the cooling rate is under 4 K/h, the crystallization products are more similar to the β form as reported, while the rate exceeds 8 K/h, the crystallization products are more similar to the β' form. By analyzing different products under different cooling rates, it is found that different products perform different crystal behavior and melting points, which provides valuable information to the optimization of the suspension crystallization.
