Food chemistry - Assignment workoutThe process does not change fatty acid composition of the starting material, therefore, interesterified oil or blends ar considered to be stable. The process makes the oils have a smoother melting point, improves plasticity as crystallization properties change. thither also is an improved functional and nutritionary property associated to interesterification (Armond, 1998).Hydrogenation is a chemical reaction that involves the addition of enthalpy across carbon-carbon multiple bonds and thus increases the saturation and the melting point. It is a process employed in the band of fats. In most cases, catalytic hydrogenation is utilised with nickel metal being the widely used catalyst. iii types of hydrogenation reactions are practiced. First is a light hydrogenation that reduces linoleic acid in soybean to produce oils with large ledge life. Second is extensive hydrogenation and third is partial hydrogenation. Partial hydrogenation involves the h ydrogenation of some and not all paradigm bonds ease up to be converted to single bonds. It is a complex process. Hydrogenation on heterogeneous catalyst is reversible and the double bonds remaining in the partially hydrogenated fat may have changed position and configuration. These affects melting point and has nutritional consequences (Frank, 2004 pg 146)Mohamed et al., (2012) developed functional fat from butter oil and moringa oleiferous oil (MOO) by interesterification. He seen a earthshaking increase in oxidative stability with the increasing augmentation of MOO blends. From his study, he concluded that MOO and BO gouge be used in the formulation of functional and shelf stable fat. Vegetable oils and fats are cognize to be stable to oxidative rancidity, healthy and pose a low risk of coronary partiality disease. In his study of oxidative stability, Mohamed et al. (2012) observed that peroxide levels at 100% augmentation of MOO were the lowest compared to levels at 50%. H igh peroxide
