In this work, the extraction by supercritical carbon dioxide of grapeseed oil from five red grape varieties was investigated. Apart from an indigenous variety Prokupac, as the domestic, and Merlot and Cabernet Sauvignon, as international grape varieties the most represented in the Republic of Serbia, Pinot Noir and Gamay were studied as well. Extraction conditions were: temperature of 50 °C, 250 bar pressure, and 0.3 kg/h flow rate of CO2. It was shown that the extraction kinetics of international grape varieties, mutually similar differ significantly from the domestic one. The obtained oil yields were in the range of 8.3% w/w (Gamay) to 10.4% w/w (Pinot Noir) for the international varieties and 5.0% w/w for the domestic variety. The mathematical model “Sovova” was applied to define transport parameters regulating the oil mass transfer inside the seed particles and determine the agreement between experimental and model curves. The interpretation of results took into account the differe...nces of grade seed morphologies (outer surfaces and inner layers) which was investigated by SEM analysis.
U ovom radu je ekstrakcija natkritičnim ugljen-dioksidom primenjena za dobijanje ulja iz
semenki crvenih sorti grožđa koje su najzastupljenije u Republici Srbiji, od kojih je sorta Prokupac
autohtona, a ostale sorte su internacionalne. Ekstrakcija je izvedena na temperaturi od 50 °C,
pritisku od 250 bar i protoku od 0,3 kg CO2 /h. Pokazano je da je kinetika ekstrakcije slična za
internacionalne sorte grožđa, a da se značajno razlikuje od kinetike ekstrakcije ulja iz autohtone
sorte Prokupac. Prinosi ulja su se kod internacionalnih sorti grožđa kretali od 8,3% (Game) do
10,4% w/w (Pinot Noir), dok je kod domaće sorte Prokupac ostvaren prinos od 4,96% w/w. Za
definisanje parametara ekstrakcije koji regulišu transport mase unutar čestica semenki primenjen
je matematički model “Sovova”. Snimanje unutrašnje i spoljašnje morfologije semenki SEM
metodom je korišćeno za interpretaciju rezultata dobijenih primenom matematičkog modela.
