比较了3种棕榈油和6种猪油产品在理化指标、营养与功能特性指标以及脂肪酸组成及其在甘油三酯Sn-2位上的分布情况,以判断棕榈油对猪油的可替代性.结果表明,棕榈油和猪油的熔点、碘值、酸值、过氧化值等理化指标很接近;棕榈油不含胆固醇,具有比猪油较高的V_E含量和氧化稳定性;在可塑性方面,精炼棕榈油与猪板油相当,而且好于猪杂油和猪膘油,棕榈硬脂与猪骨油相当,棕榈液油与猪皮油相当;虽然棕榈油和猪油的脂肪酸组成具有相似性,猪油的不饱和脂肪酸含量略高于棕榈油的不饱和脂肪酸含量,但是棕榈油的Sn-2位上主要分布不饱和脂肪酸,而猪油的Sn-2位上主要分布饱和脂肪酸,使棕榈油比猪油更加容易消化吸...

The physical and chemical indexes, nutritional and functional properties, fatty acid composition and their distribution at the Sn - 2 position of triglycerides of three kinds of palm oil products and six kinds of lard products were compared so as to judge the substitutability of palm oil for lard. The results showed that palm oil corresponded closely to lard in the physical and chemical indexes （ melting point,iodine value,acid value and peroxide value） ;palm oil had lower cholesterol content but higher VE content and higher AOM value than la...
