Abstract. Sophian A, Purwaningsih R, Lukita BL, Ningsih EC. 2018. Detection of Salmonella typhimurium ATCC 14028 in supplement health product liquid preparation using Real-Time PCR (qPCR). Biofarmasi J Nat Prod Biochem 18: 61-65. Detection of Salmonella typhimurium ATCC 14028 using Real-Time PCR (qPCR) on health supplement products was carried out in the microbiology and molecular biology testing laboratory of the Food and Drug Supervisory Office in Gorontalo. The purpose of this study was to provide an alternative testing method reference in the testing of liquid supplement health supplement products in the market. The sample consisted of 35 samples of liquid supplement health supplements spike with positive control of Salmonella typhimurium ATCC 14028 phase 2. The method used in the study was qPCR analysis using the SYBR Green method, whereas DNA isolation using the direct PCR method. Data analysis was performed based on 2 main criteria: (i) Ct (Cycle threshold) analysis, which is looking at the value of the sample Ct and comparing it with controls and (ii) analysis of melting temperature (Tm), which is the melting point at the temperature at which melt occurs and comparing the melting point to the positive control. The results showed that in the sample, Salmonella typhimurium ATCC 14028 was detected at an average Ct value of 14.43, and an average Tm value of 86.05, for the specificity, LOD and positive control tests were all amplified. For negative controls, Ct and Tm values were not detected. Based on these data it can be concluded that real-time PCR (qPCR) can be used to detect Salmonella typhimurium ATCC 14028 in liquid supplement health supplement products.
