For the gametophyte seaweed (containing κι-hybrid carrageenan and its precursors) the first 24 h extraction at room temperature resulted in an almost unrecoverable amount of carrageenan-rich precipitate (CRP) (1.6 ± 0.6 wt% of dry seaweed mass). A higher CRP yield was obtained (6.1 ± 0.6 wt% of dry seaweed mass) when a subsequent 24 h extraction was performed. Washing the gametophyte seaweed for 30 min with demineralized water prior to the first 24 h extraction reduced the conductivity of the seaweed dispersion and surprisingly improved its CRP yield (5.8 ± 0.1 wt% of dry seaweed mass). For tetrasporophytic <i>C. crispus</i> (λ-carrageenan) the first 24 h extraction at room temperature already resulted in a considerable CRP yield (18.6 ± 1.7 wt% of dry seaweed mass) despite the high conductivity of its seaweed dispersion. The CRP yield of gametophytic <i>C. crispus</i> improved with increasing extraction temperature. In the mentioned range of temperature, the maximum yield was obtained after extraction at 90 °C for 8 h (39.2 ± 0.0 wt% of dry seaweed mass). Finally, we observed at 60 °C that addition of different salts to the extraction dispersion prevented carrageenan from being extracted, with calcium salt showing the highest inhibitory effect.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Understanding the effect of time, temperature and salts on carrageenan extraction from <i>Chondrus crispus</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Seaweed; Hybrid carrageenan; Salts; Extraction parameters; Valorization","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-10-06","DateCreate":"2022-07-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000687283800007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.algal.2021.102371"},"refs":null,"anarec":{"AnaID":353479,"PubliDate":2021,"Pagination":"102371","XtraPublOfAnaID":null,"ISBN":null,"Volume":"58","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":247867,"SerRR":"Algal Research.
