Abstract

The effects of substituting coconut oil on the chemical composition, microorganism, and sensory properties of fresh sausages were investigated. This experiment evaluated three (0, 10%, 20%) levels of cold-pressed coconut oil (CPCO) and pork fat stored at 3°C for 14 days. The following treatments: 1) control (20% pork fat: 0% CPCO), 2) 0% pork fat: 20% CPCO and 3) 10% pork fat: 10% CPCO were replicated three times. Treatments were analyzed for pH value, % moisture content, % drip loss, lipid stability (thiobarbituric acid-reactive substances TBARS), aerobic plate counts, Escherichia coli, Staphylococcus aureus, and sensory analysis. The initial moisture content of fresh sausage in this experiment ranged from 63.44 to 65.67%. Fresh sausage with 20% CPCO inhibited the growth of aerobic bacteria and obtained the highest TBARS values (4.25 mg MDA/kg) compared to the control treatment. In addition, fresh sausage (10% pork fat and 10% CPCO) decreased the % drip loss, pH value and obtained the highest overall rating (6.45) of sensory testing (n = 75). No E. coli and S. aureus were found in this study for 14 d at 3°C.
