PROBLEM TO BE SOLVED: To provide oil and fat compositions deep in preferable taste originated in hydrogenated oil and fat, exhibiting oxidation stability, and capable of producing foods decreased in trans fatty acid content, and to provide a production method thereof.SOLUTION: It is found out that, in the production method of partially hydrogenated oil and fat, the oil and fat having specially deep hydrogenated oil and fat taste compared with conventionals can be produced. By oil and fat compositions compounded with a little amount of the partially hydrogenated vegetable oil and fat containing &ge0.1 ppm 3,7,11,15-tetramethyl-2-hexadecene, the oil and fat compositions having deep taste originated in hydrogenated oil and fat, exhibiting oxidation stability and decreased in trans-fatty acid content can be obtained.COPYRIGHT: (C)2011,JPO&INPIT【課題】水素添加油脂由来の好ましい風味が強く、かつ酸化安定性を示し、更にトランス脂肪酸含有量が低下した食品を製造することができる油脂組成物及びその製造方法を提供すること。【解決手段】部分水素添加油脂の製造方法において従来よりも水素添加油脂風味が格別に強い油脂を製造できることが見いだされた。本発明によって得られる3,7,11,15-テトラメチル-2-ヘキサデセン含有量を0.1ppm以上含有する部分水素添加植物油脂を少量配合した油脂組成物により、水素添加油脂由来の風味が強く、かつ酸化安定性を示し、更にトランス脂肪酸含有量が低下した油脂組成物を得ることができる。【選択図】なし
