This study aimed to evaluate the influence of chloride ions and acids on the formation of 3-MCPD, 2-MCPD, and glycidyl esters in palm oil as well as the use of metals, adsorbents, salts, amino acids, and anhydrous ethanol to simultaneously mitigate the levels of the compounds during deodorization. The concentrations of 3-MCPD and 2-MCPD esters increased more sharply in the presence of chloride (hydrochloric acid or sodium chloride). The use of zinc oxide caused a small reduction (8.5%) in 3-MCPD esters, whereas metallic zinc favored the formation of all contaminants. The levels of the substances were significantly reduced in the presence of potassium acetate (up to 98.7%), and the use of glycine decreased the concentration of chloropropanols esters by 43.8%. Anhydrous ethanol used as a stripping agent reduced the levels of 3-MCPD, 2-MCPD, and glycidyl esters by 49%, 54%, and 31%, respectively, indicating a promising strategy to mitigate these contaminants.

基于氯化物和酸对棕榈油中 3-MCPD、2-MCPD 和缩水甘油酯形成的贡献的缓解研究
本研究旨在评估氯离子和酸对棕榈油中 3-MCPD、2-MCPD 和缩水甘油酯形成的影响，以及使用金属、吸附剂、盐、氨基酸和无水乙醇同时降低除臭过程中化合物的含量。在氯化物（盐酸或氯化钠）存在下，3-MCPD 和 2-MCPD 酯的浓度增加得更快。氧化锌的使用导致 3-MCPD 酯的少量减少 (8.5%)，而金属锌有利于所有污染物的形成。在醋酸钾的存在下，这些物质的含量显着降低（高达 98.7%），而甘氨酸的使用使氯丙醇酯的浓度降低了 43.8%。用作剥离剂的无水乙醇降低了 3-MCPD、2-MCPD、
