This study aims to propose a membrane contactor process for the selective removal and recovery of SO\n                    <jats:sub>2<\/jats:sub>\n                    from wines in order to obtain its reliable quantification. Currently, the aspiration and Ripper methods offer a difficult quantification of the sulfite content in red wines because they involve evaporation steps of diluted compounds and a colorimetric assay, respectively. Therefore, an inexpensive and accurate methodology is not currently available for continuous monitoring of SO\n                    <jats:sub>2<\/jats:sub>\n                    in the liquids food industry. Red wine initially acidified at pH\u2009&lt;\u20091 was treated by membrane extraction at 25\u2009\u2103. This operation is based on a hydrophobic Hollow Fiber Contactor, which separates the acidified red wine in the shell side and a diluted aqueous sodium hydroxide solution as receiving solution into the lumenside in countercurrent. Sulfite and bisulfite in the acidified red wine become molecular SO\n                    <jats:sub>2<\/jats:sub>\n                    , which is evaporated through the membrane pores filled with gas. Thus, SO\n                    <jats:sub>2<\/jats:sub>\n                    is trapped in a colorless solution and the membrane contactor controls its transfer, decreasing experimental error induced in classical methods. Experimental results using model solutions with known concentration values of [Formula: see text] show an average extraction percentage of 98.91 after 4 min. On the other hand, two types of Chilean Cabernet Sauvignon wines were analyzed with the same system to quantify the content of free and total sulfites. Results show a good agreement between these methods and the proposed technique, which shows a lower experimental variability.\n                  <\/jats:p>","DOI":"10.1177\/1082013213494900","type":"journal-article","created":{"date-parts":[[2013,7,29]],"date-time":"2013-07-29T21:58:30Z","timestamp":1375135110000},"page":"501-510","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Extraction and quantification of SO\n                    <sub>2<\/sub>\n                    content in wines using a hollow fiber contactor"],"prefix":"10.1177","volume":"20","author":[{"given":"Andrea","family":"Plaza","sequence":"first","affiliation":[{"name":"Laboratory of Membrane Separation Processes (LabProSeM), University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julio","family":"Romero","sequence":"additional","affiliation":[{"name":"Laboratory of Membrane Separation Processes (LabProSeM), University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wladimir","family":"Silva","sequence":"additional","affiliation":[{"name":"Laboratory of Membrane Separation Processes (LabProSeM), University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Morales","sequence":"additional","affiliation":[{"name":"Laboratory of Membrane Separation Processes (LabProSeM), University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alejandra","family":"Torres","sequence":"additional","affiliation":[{"name":"Laboratory of Membrane Separation Processes (LabProSeM), University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda J","family":"Aguirre","sequence":"additional","affiliation":[{"name":"Laboratory of Conductive Polymers, University of Santiago de Chile (USACH), Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,7,29]]},"reference":[{"key":"bibr1-1082013213494900","unstructured":"AOAC.
