Stability of pelargonidin 3-glucoside in model solutions. In Polyphenols Communications 2004. XXII International Conference on Polyphenols, Helsinki. p. 627-628http://hdl.handle.net/10198/5765Methodology: Aqueous solutions of Pg 3-glucoside (1,8x10-3M in citrate buffer 0,1M at pH 3,5) were prepared and stored: (a) in the presence of oxygen (GOx) (b) in the presence of oxygen and sugars (5,7%, glucose:fructose:sacarose, 42:37:21) (GZ) (c) in anaerobic conditions (GsinOx) Solutions were stored in darkness at 25ºC for 8 months, and their evolution was followed by UV-vis spectrophotometry, HPLC-DAS and LC-MS.engPelargonidin 3-glucosideModel solutionsColor changeStorageAnthocyanin breakdown productsAerobic/anaerobic conditionsconference object
