PROBLEM TO BE SOLVED: To provide a plastic oil-and-fat composition exhibiting good plasticity, creaming property, heat-resistant shape retaining property and favorable meltability in a mouth, even when the content of saturated fatty acids is 25 to 35 mass%, and to provide a hard stock for producing the above plastic oil-and-fat composition.SOLUTION: The hard stock comprises a fractional soft oil of a transesterification oil-and-fat obtained by random transesterification of an oil-and-fat compound having such a constituent fatty acid composition that the composition contains substantially no fatty acid having less than 16 carbon atoms and contains S, which denotes saturated fatty acids having 16 or more carbon atoms, by 55 to 85 mass% and U, which denotes unsaturated fatty acids having 16 or more carbon atoms, by 15 to 45 mass%. The plastic oil-and-fat composition uses the above hard stock.COPYRIGHT: (C)2010,JPO&INPIT【課題】飽和脂肪酸含量が25~35質量%であっても、良好な可塑性、クリーミング性、耐熱保型性を有し、また、口溶けが良好である可塑性油脂組成物、及び該可塑性油脂組成物を製造するためのハードストックを提供すること。【解決手段】構成脂肪酸組成において、炭素数16未満の脂肪酸を実質的に含有せず且つSの含有量が55~85質量%でUの含有量が15~45質量%である油脂配合物を、ランダムエステル交換して得られたエステル交換油脂の分別軟部油からなることを特徴とするハードストック(但し、S:炭素数16以上の飽和脂肪酸、U:炭素数16以上の不飽和脂肪酸である)、及び該ハードストックを使用した可塑性油脂組成物。【選択図】なし
