“…This feature makes polyphenols an interesting family of compounds with broad applications such as the treatment of cancer (Hertog, 1994;Cordova & Watson, 2014) or inflammations (Kim, Lee & Lee, 2010), anti-aging aims in cosmetics (JeanGilles et al, 2013;Menaa & Menaa, 2014) or nutraceutical purposes (Göllucke, Peres, Odair & Ribeiro, 2013). Moreover, polyphenols are known to be nootropics, owing to be helpful in several functions of the brain, such as learning, memory, attention or motivation, thereby protecting the brain against neurodegenerative diseases (Mandel & Youdim, 2004;Papandreou et al, 2009;Vauzour, Kerr & Czank, 2014).…”

“…Polyphenols has a high antioxidant capacity, because they can neutralize free radicals turning them less dangerous and thereby, stopping side reactions (Dugas and others ; Tikhonov and others ; Leopoldini and others ). Therefore, this property makes them interesting for many different applications such as the treatment of inflammations (Kim and others ) or human degenerative diseases as cancer (Hertog ; Cordova and Watson ), anti‐ageing aims in cosmetics (Jean‐Gilles and others ; Menaa and Menaa ), or nutraceutical purposes (Gollücke and others ). Moreover, polyphenols are known to be nootropics, owing to be helpful in several brain functions, such as learning, memory, attention, or motivation (Papandreou and others ).…”

In this study, supercritical fluid extraction has been successfully applied to a sequential fractionation of fatty acids and polyphenols from wine wastes (2 different vitis vinifera grapes). To this aim, in a 1st step just fatty acids were extracted and in a 2nd one the polyphenols. The variables that affected to the extraction efficiency were separately optimized in both steps following an experimental design approach. The effect of extraction temperature flow, pressure, and time were thoroughly evaluated for the extraction of fatty acids, whereas the addition of methanol was also considered in the case of the polyphenols extraction. A quantitative extraction with high efficiency was achieved at a very short time and low temperatures. Concerning quantification, fatty acids were determined by means of gas chromatography coupled to mass spectrometry after a derivatization step, whereas the polyphenols were analyzed by means of high performance liquid chromatography coupled to tandem mass spectrometry and the Folin–Ciocalteu method.

“…Polifenolek ahalmen antioxidatzaile handia dute; horri esker erradikal askeak neutralizatzeko gai dira, arrisku txikiagoko konposatuak emanez [2][3][4]. Gaitasun hori dela eta, konposatu hauek egokiak dira hainbat aplikaziotarako, hala nola hanturak tratatzeko [5], minbiziaren gisako endekapenezko gaixotasunetarako [6][7] edo kosmetikan zahartzearen aurkako tratamenduetarako [8][9]. Bestalde, nootropiko bezala zerrendatuak daude, garunean oroimena, arreta eta motibazioa gisako funtzioak bultzatzen laguntzen baitute [10].…”

Laburpena: Lan honetan, optimizatu egin da bi urratseko jariakin gainkritikoaren bidezko erauzketa (SFE Supercritical Fluid Extraction), ardo hondakinetatik konposatu bioaktiboak lortzeko. Ondorioz, lortu da lehen urratsean gantz azidoak soilik eta bigarren urratsean polifenolak soilik erauztea. Polifenolek egonkortasun eskasa dute ordea. Hori dela eta, zurrusta-bibrazio bidezko mikrokapsularatzea (VNM Vibration Nozzle Microencapsulation) erabili da 150 eta 300 µm-ko zurrustekin kaltzio-alginatozko eta kaltzio-alginato-kitosanezko tamaina ezberdinetako polifenolen mikrokapsulak eratzeko. Prozesu horretan eragina duten aldagaiak optimizatu, kapsulak sortu eta haien egonkortasuna aztertu da 6 hilabetetan zehar hainbat kontserbazio-baldintzatan (4°C-ra ilunpean eta giro-tenperaturan ilunpean eta argipean). Ondorioz, ikusi da kapsulatutako polifenolen egonkortasuna baldintza guztietan kapsulatu gabeena baino askoz ere handiagoa dela.Hitz-gakoak: Ardo-hondakinak, Jariakin gainkritikoaren bidezko erauzketa, mikrokapsularatzea, gantz azidoak, polifenolak.Abstract: In this study supercritical fluid extraction (SFE) has been successfully applied to a sequential fractionation of fatty acids and polyphenols from wine wastes. Unfortunately, polyphenols have a poor long-term stability, so they were encapsulated through vibration nozzle microencapsulation using two nozzles of 150 and 300 µm and sodium alginate and sodium-alginate-chitosan as polymer. Long-term stability of the created microcapsules was studied for 6 months taking into account different storage conditions: at 4 °C in darkness, and at room temperature in darkness and in presence of light. Encapsulated polyphenols were found to be much more stable compared to free polyphenols regardless the encapsulation procedure and storage conditions.
