Plastic edible fat prodn - by hydrogenation of an animal fat-unsatd vegetable oil mixt under specified conditions

摘要

Animal fats (I) are converted to plastic edible fats by mixing 1 pt. of the molten (I) with 0.4-9 pts. of a lightly unsatd. vegetable oil and hydrogenating the mixt. at 180-220 degrees C using an H2 excess press. of =2 Kp/cm2 and an Ni catalyst whole activity is =35 degrees C so that the polyunsatd. fatty acids of (I) and (II) are selectively hydrogenated and a partial transesterification of (I) with (II) occurs. The process enables a prod. having an m. pt. of i9-40 degrees C and a hardness of 130-140 g/cm to be produced which are free from the characteristic smell and taste of (I) and which is stable during further processing esp. to margarine. Pre-determination of end-prod. props. possible. No pre-refining of (I) reqd.
