花生油中塑化剂污染的来源分析及管控方法

Source analysis and control methods of plasticizers pollution in peanut oil

为探究花生油中的邻苯二甲酸酯类物质的来源,分析了原料、与产品直接接触的材料、生产和储存过程各个环节对花生油中塑化剂含量的影响,找出了影响花生油中塑化剂含量的主要因素,并采取了针对性的措施(去除原料中的杂质;所有垫片、密封圈等使用合格材料;输油管道不使用涉塑材质;特殊油品单独处理;改进脱臭工艺),有效地控制和降低了花生油中的邻苯二甲酸酯风险,从而保证花生油的产品品质。

To study the sources of phthalate esters in peanut oil,the influences of raw materials, materials directly contacted with products, and every procedure of production and storage processes on the plasticizers content were studied,and the main factors influencing the plasticizers content in peanut oil were found out,also some targeted measures, including removing the impurities from the raw materials, applying qualified equipment parts such as gasket and rubber O-ring, using the oil pipelines containing no plastic, treating special oil separately, improving deodorization process, were adopted to effectively control and reduce the risk of plasticizers in peanut oil thus ensuring the quality of peanut oil products.
