Fortification of oil with vitamin A is considered a cost-effective, feasible strategy to prevent this problem but quality control poses a challenge to program implementation. To overcome this, we have validated a newly developed device that quantitatively measures the content of retinyl palmitate in refined palm oil, is simple to use, and yields immediate results.Linearity of analysis ranged from 2.5 - 30 mg retinol equivalents (RE)\/ kg of palm oil, with 2.5 mg RE\/kg being the determination limit; inter- and intra-assay precision ranged from 1.4 - 7.1 %. Comparison with a high-performance liquid chromatography method showed high agreement between the methods (R<jats:sup>2<\/jats:sup> = 0.92; Limits of Agreement: -1.24 mg to 2.53 mg RE\/kg), and further comparisons illustrate that the new device is useful in low-resource settings. This device offers a field- and user-friendly solution to quantifying the vitamin A content in refined palm oil. <\/jats:p>","DOI":"10.1024\/0300-9831\/a000081","type":"journal-article","created":{"date-parts":[[2013,2,2]],"date-time":"2013-02-02T02:22:37Z","timestamp":1359771757000},"page":"335-342","source":"Crossref","is-referenced-by-count":22,"title":["Quantification of Vitamin A in Palm Oil Using a Fast and Simple Portable Device: Method Validation and Comparison to High-Performance Liquid Chromatography"],"prefix":"10.31083","volume":"81","author":[{"given":"Fabian","family":"Rohner","sequence":"first","affiliation":[{"name":"GAIN - Global Alliance for Improved Nutrition, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simone K.","family":"Frey","sequence":"additional","affiliation":[{"name":"BioAnalyt GmbH, Teltow, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralf","family":"Mothes","sequence":"additional","affiliation":[{"name":"BioAnalyt GmbH, Teltow, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Hurtienne","sequence":"additional","affiliation":[{"name":"University of Potsdam, Potsdam-Rehbr\u00fccke, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simone","family":"Hartong","sequence":"additional","affiliation":[{"name":"GAIN - Global Alliance for Improved Nutrition, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrice Emery","family":"Bosso","sequence":"additional","affiliation":[{"name":"Helen Keller International, Abidjan, C\u00f4te d\u0092Ivoire"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mai","family":"Bui","sequence":"additional","affiliation":[{"name":"Swiss Vitamin Institute, Epalinges, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian J.","family":"Schweigert","sequence":"additional","affiliation":[{"name":"BioAnalyt GmbH, Teltow, Germany, and University of Potsdam, Potsdam-Rehbr\u00fccke, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Northrop-Clewes","sequence":"additional","affiliation":[{"name":"GAIN - Global Alliance for Improved Nutrition, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","container-title":["International Journal for Vitamin and Nutrition Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0300-9831\/a000081","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,8,9]],"date-time":"2024-08-09T02:10:20Z","timestamp":1723169420000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/IJVNR\/81\/5\/10.1024\/0300-9831\/a000081"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,9,1]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2011,9,1]]}},"alternative-id":["10.1024\/0300-9831\/a000081"],"URL":"https:\/\/doi.org\/10.1024\/0300-9831\/a000081","relation":{},"ISSN":["0300-9831","1664-2821"],"issn-type":[{"value":"0300-9831","type":"print"},{"value":"1664-2821","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,9,1]]}}}
