摘要

本研究的目的是研究使用金属有机框架（MOF）和天然粘土从食用油中去除3-单氯丙烷-1,2-二醇（3-MCPD）和缩水甘油酯（GEs）。首先，用吸附剂处理模型油，并选择丁氧基对苯二甲酸钛（IV）-MOF（Ti-MOF）和高岭土与天然粘土分别作为去除3-MCPD和GEs的最佳MOF。还研究了处理条件的影响，确定6.0%的吸附剂水平、120min的处理时间和95℃的温度是最佳的处理参数。最后，在选定的条件下，用Ti-MOF和高岭土处理棕榈油样品，3-MCPD和GEs的去除率分别高达27%和58%。总之，MOFs和天然粘土显示出良好的去除3-MCPD和GEs的潜力，并且可以通过改性吸附剂来提高处理效率。

Application of MOFs and natural clays for removal of MCPD and GEs from edible oils

The aim of this study was to investigate the removal of 3-monochloropropane-1,2-diol (3-MCPD) and glycidyl esters (GEs) from edible oils by using Metal Organic Frameworks (MOF) and natural clays. First, the model oil was treated with adsorbents and titanium (IV) butoxide-terephthalate MOF (Ti-MOF) and kaolin were selected as the best performing MOF along with natural clay, respectively, for the removal of 3-MCPD and GEs. The effects of treatment conditions were also investigated, 6.0% adsorbent level, 120 min treatment time and 95 ºC temperature were determined to be the best treatment parameters. Finally, palm oil samples were treated with Ti-MOF and kaolin under the selected conditions and removal of 3-MCPD and GEs was obtained at up to 27% and 58%, respectively. In conclusion, MOFs and natural clays showed good potential for the removal of 3-MCPD and GEs, and the efficiency of the treatment can be improved by modifying the adsorbents.

期刊介绍： Grasas y Aceites is a peer-reviewed journal devoted to the publication of original articles concerning the broad field of lipids, especially edible fats and oils from different origins, including non acyl lipids from microbial origin relevant to the food industry. It publishes full research articles, research notes, reviews as well as information on references, patents, and books. Grasas y Aceites publishes original articles on basic or practical research, as well as review articles on lipid related topics in food science and technology, biology, (bio)chemistry, medical science, nutrition, (bio)technology, processing and engineering. Topics at the interface of basic research and applications are encouraged. Manuscripts related to by-products from the oil industry and the handling and treatment of the wastewaters are also welcomed. Topics of special interest to Grasas y Aceites are: -Lipid analysis, including sensory analysis -Oleochemistry, including lipase modified lipids -Biochemistry and molecular biology of lipids, including genetically modified oil crops and micro-organisms -Lipids in health and disease, including functional foods and clinical studies -Technical aspects of oil extraction and refining -Processing and storage of oleaginous fruit, especially olive pickling -Agricultural practices in oil crops, when affecting oil yield or quality
