With this purpose, inulin-rich carbohydrates samples from Jerusalem artichoke tubers stored at 4–5°C during different times along an overall period of 8months were extracted. Extraction yield, inulin content and average polymerization degree of inulin-rich carbohydrates samples were also determined. For all samples, extraction yield and inulin content decreased with storage time. In particular, inulin content exhibited values within the range of commercial food grade inulin (≥85%). Average polymerization degree values decreased with storage time ranging from 12.1 to 8.3. The in vitro prebiotic activity of inulin-rich carbohydrates samples was assessed using a prebiotic activity score which considered the growing ratio relative to glucose of L. paracasei as well as of the enteric bacteria Escherichia coli when such carbohydrates were used as C source. Inulin-rich carbohydrates extracted from tubers cold-stored during 4months showed the highest prebiotic activity score, even higher than the corresponding to a commercial food grade inulin, indicating that this sample should be used as a prebiotic food ingredient, representing a potential alternative to the available commercial inulin obtained from chicory roots.","is_dataset_classified":null,"base_score":4.709530201312334,"endowment":4.709530201312334,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W2171933430","authors":[],"funders":[],"total_grants":0,"fwci":7.0756,"citation_percentile":0.97881187,"influential_citations":0,"citation_trend":[{"year":2014,"count":3},{"year":2015,"count":5},{"year":2016,"count":9},{"year":2017,"count":15},{"year":2018,"count":10},{"year":2019,"count":9},{"year":2020,"count":11},{"year":2021,"count":9},{"year":2022,"count":8},{"year":2023,"count":7},{"year":2024,"count":11},{"year":2025,"count":9},{"year":2026,"count":4}],"oa_status":"green","license":"other-oa","oa_locations":[{"url":"http://digital.cic.gba.gob.ar/handle/11746/731111746/7311","host_type":"repository"},{"url":"http://digital.cic.gba.gob.ar/handle/11746/731111746/7311","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0963996914001343?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0963996914001343?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.foodres.2014.02.024","host_type":"journal"},{"url":"https://digital.cic.gba.gob.ar/handle/11746/7311","host_type":"repository"},{"url":"http://hdl.handle.net/11336/26341","host_type":"repository"}],"fields_of_study":["Microbial Metabolites in Food Biotechnology","Food composition and properties","Diet, Metabolism, and Disease"],"mesh_terms":[],"keywords":["Inulin","Prebiotic","Lactobacillus paracasei","Jerusalem artichoke","Food science","Chemistry","Ingredient","Fructan","Lactobacillus","Fructose","Fermentation"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Zero hunger"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T23:23:01.425662Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
