　　为改善油脂可塑性和口溶性，及为开发以棕榈油产品为主要原料专用油脂产品提供理论依据，研究棕榈油硬脂（PSt）、棕榈油中间分提物（PMF）两者间相容性。测定二元混合体系固体脂肪含量（SFC）值，并通过计算其理论值与实测值之间差值△SFC，结合T–△SFC曲线、二元等温曲线等直观分析，结果表明：PSt与PMF混合物在25℃、PSt含量为30%~50%时，二者间偏晶现象严重；而在35℃~50℃时，二者间共晶现象较为严重；在0℃~10℃和30℃~35℃范围内，二者间具有较好相容性。

Compatibility study for palm stearin(PSt)and palm mid fraction(PMF)to improve the characteristics of plasticity and mouth feel melting characteristics of fats and to provide in–depth study technical data base for blending of palm oil products. The SFCs for the binary blends of palm stearin and PMF were analyzed together with the isothermal curve and the differences between theoretical to practical SFC,i.e. △SFCs. The results showed that when content of PSt was 30~50%,the blends showed marked non compatibility or serious crystals segregation and form worst monotectic at 25℃. The range of 35℃~50℃,the blends as also formed serious eutectic and promote the segregation of crystals clusters. The compatibility of PSt and PMF is most satisfactory at the ranges of 0℃~10℃and 30℃~35℃.
