Pengaruh Suhu Penyimpanan Terhadap Organoleptik, Derajat Keasaman Dan Pertumbuhan Bakteri Coliform Pada Susu Pasteurisasi Image
Abstract

One attempt to reduce the number of pathogenic microbes in milk is through the pasteurization process. This research aims to determine the effect of storage temperature on the organoleptic, acidity (pH) and growth of coliform bacteria in pasteurized milk. Pasteurized milk is stored at the varies of temperature 4°C (observed for 14 days), 10°C-15°C (observed for 14 days) and 25°C-27°C (observed for 22 hours), as well as also conducted an initial analysis pasteurized milk. The parameters were observed among other organoleptic (smell, taste, color, texture), pH and total coliform bacteria. Testing acidity using pH paper, while the growth of coliform bacteria testing done using Total Plate Count method based on ISO 2897 in 2008. The results of this study indicate that storage at 4°C for 14 days, organoleptic pasteurized milk is still good until the day ke- 8, pH progressively decreases, and the growth of coliform bacteria obtained the highest score of 3100x101 CFU / ml. Storage at 10°C-15°C for 14 days, organoleptic pasteurized milk is still good until the 6th day, the pH progressively decreases, and the growth of coliform bacteria obtained the highest score of 5729x101 CFU / ml. Storage at 25°C-27°C for 22 days, organoleptic pasteurized milk is still good until the 9th, pH progressively decreases, and the growth of coliform bacteria obtained the highest score of 4.3 x106 CFU / ml.
