Abstract
Abstract:Cholesterol oxidation products (COPs) have been shown potentially atherogenic, mutagenic andcarcinogenic effects towards human. Storage of food will increase the production of COPs. The objective ofthis research is to investigate the effect of cold storage (chilled storage, 4°C and frozen storage, -20°C) on fattyacids content and formation of cholesterol oxides in three different lipid sources of sausage productscontaining chicken fat (CF), Super Olein (SO) and Red Palm Stearin (RPS).Three types of chicken sausages withdifferent lipid sources: CF, SO and RPS were prepared and stored in chiller for zero, first, second and third weeksand stored frozen for zero, fourth and eight weeks. Fatty Acids and COPs in samples were extracted andanalyzed using gas chromatography with flame ionization detector (FID). The reduction of unsaturated fattyacids, cholesterol content and formation of cholesterol oxides were found during throughout the storage life.The Red Palm Stearin (RPS) samples showed significant increment of the total saturated fatty acid comparedto Super Olein (SO) and chicken fat (CF). It was concluded the saturated fatty acids (SFA) andmonounsaturated fatty acids (MUFA) increased in comparison to polyunsaturated fatty acids (PUFA) in allsamples during chilled storage and the amount of COPs were in the following order; CF>SO>RPS. It implies thatsausages formulated with SO and RPS are effective in reducing COPs formation. The recommendations are towider the range of COPs reference standards.
