Abstract

Detection of pathogenic bacteria Listeria monocytogenes in processed food products of frozen meatballs is one of the critical test parameters in product quality testing. The challenge in testing product quality is how to find a reliable and effective test method to generate test results data. With this research, it is hoped that it can provide information or references for similar research. The method used in this research is the enrichment method with a direct isolation technique and amplification using real-time PCR. Data analysis was carried out based on 2 main criteria which included: (1) Ct analysis (Cycle threshold) and (2) melting temperature (Tm) analysis. From the results of the analysis using real-time PCR, the results of the tested samples were detected at Ct 11.60 with a Tm value of 81.50. For NTC control not detected, this indicates that the master mix used is in good condition and no contamination occurred when testing the sample. The use of this NTC control plays an important role in monitoring the quality of the master mic and test run. For the LOD control and positive control, the results were detected, whereas in the LOD control, the Ct value was detected at 10.08 and the Tm value was at 81.30. for positive control, the value of Ct was detected at 10.85 and the value of Tm was at 82.0. Based on the results of the study, it can be concluded that the test method used can detect Listeria monocytogenes in processed meat products in the form of frozen meatballs.

Abstract

Gummy candy is a type of soft candy who made from juice and gel-forming materials. The objective of this research was to determine the effect of variation of pectin and sugar concentration on physical and chemical characteristics of passion fruit (Passiflora edulis) gummy candies. The research using factorial completely randomized design with two factors, namely concentration variation of pectin (1%, 1,5%, 2%) and concentration variation of sugar (30%, 40%, 50%). The observed parameters included physical characteristics (color, elasticity) and chemical characteristics (water content, ash content, pH, vitamin C, reducing sugar content, total acid). The result showed that concentration of pectin significantly affected on color (lightness, redness, yellowness), elasticity, water, ash, vitamin C, reducing sugar content, and total acid content, where as concentration of sugar significantly affected on color (lightness, yellowness), elasticity, water, ash, pH, vitamin C, reducing sugar content, and total acid content. The interaction affected significantly on elasticity, water, reducing sugar content, and total acid content. A3B2 treatment (pectin concentration 2% and sugar concentration 40%) was the best treatment based on parameters of water content (17.41%), ash content (1.06%), and reducing sugar content (8.28%).
