Abstract: There is provided an oil or fat composition composed chiefly of triglycerides wherein the amount of medium-chain fatty acids in all the fatty acids composing the oil or fat composition is 5 to 23% by mass and the amount of triglycerides having two medium-chain fatty acid residues in the molecule in all the triglycerides is 1 to 20% by mass. The oil or fat composition is low in body fat accumulation, has equal cooking properties with conventional edible oils and has good flavor and high safety.

Abstract: 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.

Abstract: The disclosed apparatus comprises a movable carriage on which an industrial television camera and nondestructive examining unit or probe are swingably supported. A control means for controlling the carriage, industrial television camera and the probe are also provided as is a monitor television for displaying the result of an examination made by the probe and a video tape recorder.
