“…A number of studies have investigated the influence of chemical interesterification on the physico-chemical properties of oils and fats or their blends, including the work of Gioielli and Baruffaldi (1988), List, Emken, Kwolek, Simpson, and Dutton (1977), List, Mounts, Orthoefer, and Neff (1995), Lida and Ali (1998), Rousseau (1998a, 1998b), Petrauskaite, De Greyt, Kellens, and Huyghebaert (1998), Kok, Fehr, Hammond, and White (1999), Khatoon (2000), Rodríguez, Castro, Salinas, López, and Miranda (2001), Rodrigues, Gioielli, and Anton (2003), , Norizzah et al (2004), Karabulut, Turan, and Ergin (2004), Ramli, Said, and Loon (2005), Grimaldi, Gonçalves, and Ando (2005), Khatoon and Reddy (2005), Silva and Gioielli (2006), Piska, Zárubová, Louzecký , Karami, and Filip (2006), and others. The interesterification of liquid oils with hardfats is the most versatile way for producing zero trans fats, yielding fat bases with excellent characteristics for preparation of margarines, shortenings and spreads (Karabulut et al, 2004;Khatoon & Reddy, 2005;List et al, 1995;Lo & Handel, 1983 In world vegetable oil consumption, soybean oil (SO) stands out for its nutritional qualities, permanent supply, considerable economic value and high functionality, making it a particularly interesting raw material for producing special fats (O'Brien, 2004).…”
