    • An immobilized lipase is prepared for transesterification of oils, fats or phospholipids in a reaction system containing a very small amount of water such as 50 to 2,000 ppm. The lipase may be a phospholipase such as phospholipase A.sub.2. In a first embodiment, lipase from a microorganism of the genus Rhizopus, Mucor, Alcaligenes or Candida is immobilized on the surface of a hydrophobic, insoluble organic polymer carrier having pores of an average diameter of 10 nm or larger. A solution of lipase is contacted with the polymer carrier for 10 minutes to 40 hours to covalently bond the lipase to the carrier. The immobilized lipase is dried under reduced pressure to a water content of 0.5 to 30 wt %. In a second embodiment, lipase is immobilized on the surface of a polymer carrier such as a hydrophobic, insoluble organic polymer carrier having a pore diameter of 5 to 1,000 nm and having a functional group capable of binding lipase in a aqueous solution and an anion-exchange group on the surface. Preferably, the functional group is an epoxy group and the anion-exchange group is a tertiary amino group. The lipase may be obtained from the same microorganism as in the first embodiment or from another lipase-producing microorganism. Immobilization can be carried out as in the first embodiment. It is preferred to contact a solution of lipase with the polymer carrier in the presence of a fatty acid or derivative thereof for 10 minutes to 10 hours to covalently bond the lipase to the polymer carrier.

    • A process for producing a salad oil comprises transesterifying a mixture of (A) an oil or fat produced from palm oil and having the following characteristics:______________________________________ iodine value: 55 to 75 constituent fatty acids: palmitic acid: 30 to 42% by weight oleic acid: 42 to 48% by weight linoleic acid: 11 to 20% by weight tripalmitin: 2% by weight or less open-tube melting point: 5 to 25.degree. C. ______________________________________ and (B) a liquid edible oil other than the component (A) in a weight ratio of 5:95 to 95:5 with immobilized lipase having 1,3-specificity in the absence of solvent and then fractionating the product in the absence of solvent. Thereby, the salad oil can be efficiently derived from palm oil which is a solid oil and the relative amount of the starting material obtained from palm oil in the salad oil can be increased. The thus-produced salad oil has a satisfactory cooling resistance.
