Among other wastes, coffee silver skin (CSS) is highly available and more stable due to its lower content of water. This research aimed to characterize coffee silver skin composition and evidence its potentiality for use as a food-safe ingredient in new formulations. Results showed an average total dietary fiber content of 50% but with a higher ratio for insoluble than soluble fiber. A high content of total phenolic compounds, chlorogenic acid, caffeine, and caffeic acid was found and correlated with the high measured antioxidant capacity. Moreover, minerals (e.g., calcium, magnesium, phosphorous, potassium, copper, iron, manganese) important for human wellbeing were found at a high level in CSS, while toxic minerals (e.g., nickel) were found at low levels. In conclusion, coffee silver skin could have an advantageous role for the recovery of valuable compounds and as a potential food-safe ingredient.<\/jats:p>","DOI":"10.3390\/foods10061367","type":"journal-article","created":{"date-parts":[[2021,6,14]],"date-time":"2021-06-14T10:30:25Z","timestamp":1623666625000},"page":"1367","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":68,"title":["Characterization of Coffee Silver Skin as Potential Food-Safe Ingredient"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5919-305X","authenticated-orcid":false,"given":"Maria","family":"Martuscelli","sequence":"first","affiliation":[{"name":"Faculty of Bioscience and Technology for Food, Agriculture and Environment, University of Teramo, Via R.
