The chemical product design method was used to select the best idea based on 4 steps: needs, ideas, selection, and manufacturing.Liquid xylitol is here proposed for the valorisation of tomato plant residues, which is an alternative sweetener with a lower glycemic index that can be produced from the hemicellulose found in leaves and stems. Its production would require an alkaline extraction with sodium hydroxide, enzymatic hydrolyses using endo-1,4-\u03b2-xylanase, and yeast fermentation with Candida tropicalis.Liquid sweetener with 72% xylitol and other components (D-glucose, D-mannose, D-galactose, L-arabinose, and lignin), commercialised as NITS - Natural Incredible Tomato Sweetener, could be sold for 2.25 \u20ac\u00b7L-1 for companies and the same price per bottle of 500 mL for individual consumption.<\/jats:p>","DOI":"10.24840\/2183-6493_008.005_0014","type":"journal-article","created":{"date-parts":[[2022,9,27]],"date-time":"2022-09-27T16:04:29Z","timestamp":1664294669000},"page":"158-174","source":"Crossref","is-referenced-by-count":0,"title":["Xylitol"],"prefix":"10.24840","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8893-2977","authenticated-orcid":false,"given":"Filipa","family":"Carvalho","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1624-2058","authenticated-orcid":false,"given":"Francisca","family":"Duarte","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4631-4745","authenticated-orcid":false,"given":"Laura","family":"Pedreiras","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6614-167X","authenticated-orcid":false,"given":"Vanessa","family":"Posada","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1134-1743","authenticated-orcid":false,"given":"Margarida","family":"Brito","sequence":"additional","affiliation":[]}],"member":"10468","published-online":{"date-parts":[[2022,9,27]]},"container-title":["U.Porto Journal of Engineering"],"original-title":[],"link":[{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/download\/2183-6493_008-005_0014\/694","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/download\/2183-6493_008-005_0014\/694","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,9,27]],"date-time":"2022-09-27T16:04:48Z","timestamp":1664294688000},"score":1,"resource":{"primary":{"URL":"https:\/\/journalengineering.fe.up.pt\/index.php\/upjeng\/article\/view\/2183-6493_008-005_0014"}},"subtitle":["Development Study of a Liquid Sweetener derived from Hemicellulose of Tomato Agricultural Wastes"],"short-title":[],"issued":{"date-parts":[[2022,9,27]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2022,9,27]]}},"URL":"https:\/\/doi.org\/10.24840\/2183-6493_008.005_0014","relation":{},"ISSN":["2183-6493"],"issn-type":[{"type":"electronic","value":"2183-6493"}],"subject":[],"published":{"date-parts":[[2022,9,27]]}}}
