| 中文摘要: |
| 3-氯丙醇酯（3-MCPDEs）和缩水甘油酯（GEs）是食用植物油精炼过程中形成的新型污染物，其食品安全风险备受关注。系统综述了3-MCPDEs和GEs的形成机制与国内外限量标准，比较了直接法、间接法及其他检测方法的特点与局限，指出高选择性衍生剂和非衍生化实时检测是未来重要方向。对天津市售17类35个食用植物油样品进行了实证分析，结果显示，棉籽油、棕榈油、稻米油中3-MCPDEs和GEs污染突出，橄榄油、椰子油等低温压榨油几乎未检出3-MCPDEs和GEs。同时，基于全链条风险管控视角，提出了极性溶剂清洗除氯→水法脱胶→优化脱酸→吸附脱色→双温脱臭/短程蒸馏→后精炼辅助的集成工艺，为降低食用植物油中3-MCPDEs与GEs水平、保障食用植物油安全提供了可行路径。 |
| 英文摘要: |
| 3-Monochloropropane-1,2-diol esters (3-MCPDEs) and glycidyl esters (GEs) are emerging contaminants formed during the refining process of edible vegetable oils, and their food safety risks have attracted considerable attention. The formation mechanisms of 3-MCPDEs and GEs, as well as domestic and international regulatory limits, were systematically reviewed. The characteristics and limitations of analytical methods such as direct, indirect, and other methods were compared, and the important future direction of the highly selective derivatization reagents and non-derivatization real-time detection was pointed out. An empirical analysis was conducted on 35 commercially available edible vegetable oil samples from 17 categories in Tianjin. The results showed that cottonseed oil, palm oil, and rice bran oil exhibited significant contamination with 3-MCPDEs and GEs, whereas low-temperature pressed oils such as olive oil and coconut oil were nearly undetectable. Furthermore, from a holistic risk management perspective across the entire supply chain, an integrated process of polar solvent chlorine removal → water degumming→optimized deacidification→adsorption decolorization→ dual-temperature deodorization/short-path distillation→ post-refining assistance was proposed, which could provide a viable pathway for reducing the levels of 3-MCPDEs and GEs in edible vegetable oils and ensuring edible vegetable oil safety. |
