Utility of Moringa oleifera waste as a coagulant in goat soft cheese production

Milk clotting enzyme (MCE) of Moringa oleifera from prepared seed cake (PSC) dissolved in acetate buffer pH 5.0 recorded the highest activity compared to other samples, as well as 20-40% saturation of ammonium sulfate precipitated MCE with 28.20% yield and 1.01 purification fold. The proteolytic activity (PA) of crude MCE from Moringa oleifera PSC was higher than those of partial purified MCE with 180.81 and 155.47 as MCA/PA ratio, respectively. PSC moringa MCE exhibited their optimal activity at pH 5.0 and 60 °C; it could be capable to coagulate different milk types. Also, goat soft cheeses coagulated with moringa MCE exhibited significantly (p ≤ 0.05) higher levels of water soluble nitrogen content and total sensorial scores than control cheese. It could be concluded that partial purified MCE from Moringa oleifera PSC may prove to be a good candidate in goat cheese production without any appeared defects during their storage period.
