The antioxidants included propyl gallate, octyl gallate, dodecyl gallate, butylated hydroxyanisole, butylated hydroxytoluene, <jats:italic>tert<\/jats:italic>\u2010butylhydroquinone and \u03b1\u2010tocopherol. They were resolved in 11\u2009min using a low pH microemulsion containing 20% propan\u20102\u2010ol. Theoretical plates in the range 39\u2009000\u201395\u2009000 <jats:italic>per<\/jats:italic> length of column (38.5\u2009cm) were recorded for the antioxidants. The LODs were calculated to be in the range 9\u201344\u2009\u03bcg\/mL (30\u2009s hydrostatic injection and a 50\u2009\u03bcm id capillary column). The method can also be used to simultaneously analyse for the synthetic preservatives sorbic acid, benzoic acid, salicylic acid and the parabens. The method was successfully applied to noodles for the determination of butylated hydroxytoluene and propyl gallate and to pharmaceutical supplement tablets for \u03b1\u2010tocopherol. The in\u2010capillary concentration of butylated hydroxytoluene by sweeping was also demonstrated.<\/jats:p>","DOI":"10.1002\/elps.201000050","type":"journal-article","created":{"date-parts":[[2010,6,7]],"date-time":"2010-06-07T13:15:56Z","timestamp":1275916556000},"page":"2267-2271","source":"Crossref","is-referenced-by-count":14,"title":["Determination of food grade antioxidants using microemulsion electrokinetic chromatography"],"prefix":"10.1002","volume":"31","author":[{"given":"Vishal","family":"Darji","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary C.","family":"Boyce","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian","family":"Bennett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael C.","family":"Breadmore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joselito","family":"Quirino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,6,30]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1522-2683(200105)22:8<1447::AID-ELPS1447>3.0.CO;2-#"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-4522.2007.00098.x"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2006.12.025"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0308-8146(01)00176-5"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00216-006-0738-1"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(99)00411-2"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02662289"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2005.01.015"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2006.01.013"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.foodchem.2005.10.018"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/jf980959u"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(98)01019-X"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(00)00117-5"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200900568"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2006.01.048"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200600463"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200700280"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.200800435"}],"container-title":["ELECTROPHORESIS"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Felps.201000050","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/elps.201000050","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,15]],"date-time":"2025-10-15T17:29:42Z","timestamp":1760549382000},"score":1,"resource":{"primary":{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/10.1002\/elps.201000050"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,6,30]]},"references-count":18,"journal-issue":{"issue":"13","published-print":{"date-parts":[[2010,7]]}},"alternative-id":["10.1002\/elps.201000050"],"URL":"https:\/\/doi.org\/10.1002\/elps.201000050","archive":["Portico"],"relation":{},"ISSN":["0173-0835","1522-2683"],"issn-type":[{"type":"print","value":"0173-0835"},{"type":"electronic","value":"1522-2683"}],"subject":[],"published":{"date-parts":[[2010,6,30]]}}}
