  The present invention aims at providing fat-and-oil compositions which can effectively inhibit the migration of water even when a low-water-content component is in contact with a high-water-content component and foods made by using the same. Namely, a fat-and-oil composition for inhibiting the migration of water in food wherein the fat-and-oil component contains a 1,2-saturated-3-unsaturated glyceride (SSU) in an amount of 15wt% or above but preferably below 50 wt% and a 1,3-saturated-2-unsaturated glyceride (SUS) in an amount of less than 50 wt%; fat-and-oil compositions as described above which further contain at least one member selected from among mono-diglycerides, sorbitan tristearate, and acetylated sucrose fatty acid esters, or a solid matter other than fats and oils; and foods containing, between low-water-content regions and high-water-content regions, the fat-and-oil compositions for inhibiting the migration of water.

  本发明旨在提供即使在低含水量成分与高含水量成分接触时也能有效抑制水分迁移的油脂组合物以及使用该组合物制成的食品。即，一种用于抑制食品中水分迁移的油脂组合物，其中的油脂成分含有1,2-饱和-3-不饱和甘油酯（SSU），含量为15wt%或以上，但最好低于50wt%，以及1,3-饱和-2-不饱和甘油酯（SUS），含量低于50wt%；如上所述的油脂组合物，其中还含有至少一种选自单甘油酯、山梨糖醇三硬脂酸酯和乙酰化蔗糖脂肪酸酯的成分，或油脂以外的固体物质；以及在低含水量区和高含水量区之间含有上述油脂组合物的食品，用于抑制水的迁移。

  There is provided a process for preparing a fat and oil having a 1,3-disaturated long-chain fatty acid 2-monounsaturated long-chain fatty acid triglyceride (SUS)/1,2-disaturated long-chain fatty acid 3-monounsaturated long-chain fatty acid triglyceride (SSU) mass ratio of 9/1 or more, which comprises conducting transesterification of a fat and oil containing SUS of 50% by mass or more and SSU with an action of a 1,3-selective lipase selected from the group consisting of lipases derived from Thermomyces sp., Rhizopus oryzae and Rhizopus delemar. This process is an industrially suitable process for preparing a hard butter which has excellent properties as a cacao butter equivalent (CBE) or cacao butter improver (CBI).

  提供了一种用于制备 1,3-二饱和长链脂肪酸 2-单不饱和长链脂肪酸甘油三酯 （SUS）/1,2-二饱和长链脂肪酸 3-单不饱和长链脂肪酸甘油三酯（SSU）质量比为 9/1 或以上的油脂的工艺、其中包括在 1，3-选择性脂肪酶的作用下，对含有 SUS（质量分数为 50%或以上）和 SSU 的油脂进行酯交换反应，该脂肪酶选自热酵母菌（Thermomyces sp.,Rhizopus oryzae 和 Rhizopus delemar。该工艺是一种适用于工业化生产的硬黄油制备工艺，它作为可可黄油等同物（CBE）或可可黄油改良剂（CBI）具有极佳的特性。

  The present invention discloses a method for producing fats and oils rich in a X2U triglyceride, which comprises the step of fractionating fats and oils which comprise 20 to 60 mass % of a di-saturated mono-unsaturated triglyceride (X2U triglyceride) consisting of two saturated fatty acid residues and one unsaturated fatty acid residue in total triglycerides in the presence of 1 to 50 mass % of a fatty acid lower alkyl ester comprising 10 to 100 mass % of an unsaturated fatty acid lower alkyl ester. This method is a more efficient and industrially suitable fractionation and production method of fats and oils rich in a di-saturated mono-unsaturated triglyceride (X2U triglyceride).

  本发明公开了一种生产富含 X2U 甘油三酯的油脂的方法、该方法包括以下步骤：在含有 1 至 50 质量％的脂肪酸低级烷基酯（其中 10 至 100 质量％为不饱和脂肪酸低级烷基酯）的情况下，分馏出在甘油三酯总量中含有 20 至 60 质量％的由两个饱和脂肪酸残基和一个不饱和脂肪酸残基组成的二饱和单不饱和甘油三酯（X2U 甘油三酯）的油脂。该方法是一种更高效、更适合工业化生产的富含二饱和单不饱和甘油三酯（X2U 甘油三酯）的油脂分馏和生产方法。
