Abstract

This study was conducted to determine the contamination of microorganisms, pH, water activity (aw), as well as sensory tests (color, aroma, flavor, and texture) with the presentation of different cheeses. This research was conducted in an Laboratorium Terpadu and Laboratorium Phatogen, Teknologi Hasil Ternak, Program Study Ilmu Produksi dan Teknologi Peternakan, Fakultas Peternakan, Bogor Agricultural University. Data from the observations in doing calculations using t-test mathematical model of this design is t =  with 2 times each replicate. The variables measured were the value of Total Plate Count (TPC), Potato Dextrote Agar (PDA), pH, aw, and a sensory test. Data were analyzed using t-test model. The results of the analysis of the t-test (α = 5%) of cheddar cheese block and cheddar cheese slice stem not give significant differences (P > 0,05) on the TPC and PDA yeasts or fungi. t-test (α = 5%) to pH and aw on each individual cheese does not give significant differences (P> 0,05). From the results of sensory analysis on the color of the cheese is seen that the panelists really liked the cheese sticks. Rate on cheese stem higher with the average value of which is 4 compared with cheddar cheese shaped slice which has an average value is 3,7. as well as on the assessment of texture and flavor, the rod-shaped cheddar cheese has a value - average higher than shaped slice of cheddar cheese. while the aroma cheddar cheese slice has a higher average value than the rod-shaped cheddar cheese. However this is seen not provide a significant difference due to differences in cheese and cheese slice stem relatively small. On the results of the analysis (t-test) showed that the difference in assessment of color, texture, aroma and taste of the cheese slice and cheese stems not significant or not significant. This is most likely because of the cheese slice and rods produced by the company that produced simultaneously.

Abstract

The aim of this study was to determine the physical, chemistry, and microbiological quality of goat’s milk collected from morning and afternoon milking. A total of 3 of crossbred goat (PE) milk were used in this study. These samples were analyzed for total plate count (TPC), Staphylococcus sp, Escherichia coli, and Salmonella sp. Test anova shown any significant differences ( p<0,05) in Escherichia coli while  another microorganisms not significant. For quality physical and chemical anova results showed no difference between morning and afternoon milking. Based on Indonesian National Standard (SNI) for fresh milk No 3141.1-2011, the level of TPC, and Salmonella sp.were still in standard range, while Staphylococcus sp.and Escherichia coli  was exceed the standard value. In conclusion, raw milk of goat collected directly from the udder is safe to consume.

Abstract

This study aimed to evaluate the quality of physical, microbiological and organoleptic chicken sausage around on campus IPB, Bogor to evaluate its feasibility. Chicken sausage samples obtained from two groups of different markets, namely supermarket and traditional market. The design of the treatment of this study consisted of two treatment that sausage that comes from the traditional markets (stored at room temperature) and sausage that comes from the supermarket (stored at cold temperatures) and each market was taken a sample of three replications. The physical quality was observed pH and aw, while the microbiological quality was observed quantitative testing total microbial colonies (PCA), E. coli, Salmonella sp, Staphylococcus aureus, according to the  BSN (2008) and FDA method (1998). Organoleptic quality chicken sausage test was using hedonic test. The results showed that the chicken sausages in the market around the campus of IPB was still feasible for consumption due to microbial contamination was still low compared with SNI and organoleptic sausage was still accepted by the panelists
