The present invention discloses a method of producing triglycerides rich in XOX fat and/or XLX fat, which comprises the steps of heating and dissolving triglycerides (XOX fat and/or XLX fat) which comprise 20 to 60 mass %of a triglyceride having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position in total triglycerides in the presence of 1 to 30 mass % of a fatty acid lower alkyl ester; and then cooling the mixture to precipitate crystals and conducting solid-liquid separation. This method is a more efficient and industrially suitable fractionation and production method of fats and oils which are rich in a triglyceride (XOX fat and/or XLX fat) having a saturated fatty acid residue on each of the first and third position and an oleoyl group and/or a linoleoyl group on the second position.
本发明公开了一种生产富含 XOX 脂肪和/或 XLX 脂肪的
甘油三酯的方法,该方法包括以下 步骤:加热和溶解
甘油三酯(XOX 脂肪和/或 XLX 脂肪),该
甘油三酯在全部
甘油三酯中包含 20 至 60 质量百分比的
甘油三酯,这些
甘油三酯的第一位和第三位上各有一个饱和
脂肪酸残基,第二位上有一个油酰基和/或亚油酰基,同时存在 1 至 30 质量百分比的
脂肪酸低级烷基酯;然后冷却混合物以析出晶体并进行固液分离。该方法是一种更高效、更适合工业化生产的油脂分馏和生产方法,其富含一种
