摘要： There is disclosed a process for modifying fats and oils by an interesterification reaction to efficiently increase concentrations of the desired triglycerides. In the process, a step for subjecting a fat or oil to an interesterification reaction with a fatty acid or its lower alcohol ester in the presence of an enzyme catalyst and then a step for removing the fatty acid or its lower alcohol ester by distillation are repeated in multiple stages. The process is characterized by leaving the fat or oil and a feedstock fatty acid or its ester selectively in the distillation steps preceding the one in the final stage. According to this process, the amount of the fatty acid or its ester to be used can be reduced and the formation of by-products can be inhibited, thereby enabling to increase concentrations of the desired triglycerides more efficiently than conventional multistage interesterification processes.

摘要： An objective lens system for a microscope has a high magnification and high numerical aperture. Corrections for various aberrations, and especially coma, can be made over a wide field of view. The system can be used as an objective lens system for a fluorescence microscope. The objective lens system contains a first lens group which has multiple lenses placed in sequence as counted from the object side. The first lens group has a positive focal power. A second lens group includes a first compound lens, prepared by cementing a negative meniscus lens with its convex surface facing the object side and a biconvex lens, and a second compound lens, prepared by cementing a biconcave lens and a biconvex lens. A third lens group has multiple lenses and a negative focal power. A change in aberration can be corrected for by moving the second lens group with respect to the first and third lens groups along the optical axis. The objective lens system meets certain prescribed conditions.
