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.ABSTRAKSalah satu usaha untuk mengurangi jumlah mikroba patogen pada susu adalah melalui proses pasteurisasi. Penelitian ini bertujuan untuk mengetahui pengaruh suhu penyimpanan terhadap organoleptik, derajat keasaman (pH) dan pertumbuhan bakteri Coliform pada susu pasteurisasi. Susu pasteurisasi disimpan pada suhu yang bervariasi yaitu suhu 4°C (diamati selama 14 hari), suhu 10°C-15°C (diamati selama 14 hari) dan suhu 25°C-27°C (diamati selama 22 jam), serta dilakukan pula analisa awal susu pasteurisasi. Parameter yang diamati antara lain organoleptik (bau, rasa, warna, tekstur), pH dan jumlah bakteri Coliform. Pengujian derajat keasaman menggunakan kertas pH, sedangkan pengujian pertumbuhan bakteri Coliform dilakukan dengan menggunakan metode Total Plate Count berdasarkan SNI 2897 Tahun 2008. Hasil penelitian ini menunjukkan bahwa penyimpanan pada suhu 4°C selama 14 hari, organoleptik susu pasteurisasi masih baik sampai dengan hari ke-8, pH semakin lama semakin menurun, dan pertumbuhan bakteri Coliform didapatkan nilai tertinggi sebesar 3100x101 Cfu/ml. Penyimpanan pada suhu 10°C-15°C selama 14 hari, organoleptik susu pasteurisasi masih baik sampai hari ke-6, pH semakin lama semakin menurun, dan pertumbuhan bakteri Coliform didapatkan nilai tertinggi sebesar 5729x101 Cfu/ml. Penyimpanan pada suhu 25°C-27°C selama 22 hari, organoleptik susu pasteurisasi masih baik sampai jam ke-9, pH semakin lama semakin menurun, dan pertumbuhan bakteri Coliform didapatkan nilai tertinggi sebesar 4,3 x106 Cfu/ml.Kata kunci : bakteri coliform, derajat keasaman, suhu penyimpanan, organoleptik, susu pasteurisasi

Abstrak: Susu merupakan produk hasil ternak berupa cairan putih dengan kandungan gizi yang lengkap serta memberikan manfaat bagi tubuh manusia. Sebagai upaya dalam meningkatkan kesadaran masyarakat dalam pemahaman berbagai produk olahan susu maka diadakan penyuluhan. Pengabdian ini telah dilaksanakan kepada masyarakat Desa Cisempur Kecamatan Jatinangor dengan diikuti sebanyak 22 peserta yang terdiri atas kalangan ibu rumah tangga. Metode pelaksanaan dengan cara partisipasi aktif dari peserta dengan pengenalan berbagai produk olahan susu. Tahapan dimulai dengan sebaran kuisioner pre test  sebelum kegiatan dilakukan dengan 20 pertanyaan yang diajukan, lalu pemaparan materi berbagai olahan susu mulai dari pendahuluan terkait susu sampai produk olahan susu, Penyebaran kuisioner Post test kepada peserta setelah acara selesai dengan pertanyaan yang sama seperti pre test. Kemudian membuat salah satu produk susu kepada peserta berupa susu pasteurisasi. Hasil menunjukkan bahwa terjadi peningkatan pengenalan produk olahan susu pada masyarakat Desa Cisempur Kecamatan Jatinangor yang hadir setelah melakukan pre test dan post test.Abstract: Milk is a livestock product in the form of a white liquid with complete nutritional content and provides benefits to the human body. As an effort to increase public awareness in understanding various dairy products, counseling was held. This service has been carried out for the community of Cisempur Village, Jatinangor District, followed by 22 participants consisting of housewives. The method of implementation is by means of active participation of the participants with the introduction of various dairy products. The stages began with the distribution of pre-test questionnaires before the activity was carried out with 20 questions, then the presentation of various dairy products, from the introduction to milk to dairy products, the distribution of post test questionnaires to participants after the event was over with the same questions as the pre test. Then make one of the milk products for the participants in the form of pasteurized milk. The results showed that there was an increase in the introduction of dairy products in the people of Cisempur Village, Jatinangor District who attended after doing the pre test and post test.

SummaryThe proteolysis of highly purified samples of αs1-, αs2-, β-and κ-caseins by porcine plasmin and by bovine plasminogen with urokinase has been examined principally by gel electrophoresis. The resulting peptide band patterns were compared with those of total proteose-peptone (TPP) samples prepared from fresh and stored raw and pasteurized milk, and also with those obtained during the natural course of proteolysis by indigenous enzymes in milk during storage. TPP was found to contain at least 38 components detectable by a single electrophoresis run. Apart from residual traces of whey proteins and intact caseins nearly all of these components were fragments of caseins produced by indigenous plasmin, with products from the breakdown of αs1- and β-casein predominating. Over 90 % of TPP has been accounted for in this way. A fragment consisting of residues 29–105 of β-casein was isolated and characterized from both stored milk and from plasmin digests of β-casein. This fragment was a relatively major product of the natural proteolysis occurring during storage of milk, but contrary to a report in the literature it was not the same as proteose-peptone component 8-slow. Since many of the components of TPP resulted from proteolysis, the composition of TPP was found to vary according to the time and temperature of storage of the milk from which it was prepared. Thus, while the proteose-peptone fraction of milk can easily be defined operationally it cannot be rigorously defined in terms of its composition unless the history of the milk is also defined.

White Spots

Swiss cheese made from fully pasteurized milk developed white spots during hot room stay. This cheese was bitter and eye development was generally retarded. Streptococcus faecalis subsp. liquefaciens was isolated in high numbers from the spot; it caused bitterness in milk cultures with complete dissolution of the milk clot. The isolate was inhibitory to propionibacteria and Lactobacillus fermentum; CO2 production by Propionibacterium was depressed in broth culture in the presence of the S. faecalis subsp. liquefaciens isolate.
