Background: There is a genuine interest in the development of probiotic milk and juice based beverages because they are a good-vehicle to deliver probiotic microorganisms to consumers. For this purpose, the viability and metabolism of four probiotic strains (Lactobacillus acidophilus LA5, Bifidobacterium lactis BB12, L. rhamnosus and L. plantarum) were studied in non-fermented milk and carrot j...

Our objective was to determine the temperature and vacuum relationships for efficient removal of added CO2 from raw milk. Added CO2 in milk and dairy products inhibits the growth of spoilage organisms during refrigerated storage and shipping. As milk and milk concentrates are shipped over longer distances, the use of CO2 is becoming more common to maintain raw milk quality. In most cases, some ...

This study describes the effect of bactofugation (10,000 × g in a continuous flow 10,000 L/h) three batches raw milk on total bacterial count (TBC) and aerobic spore count, it also shows microbial diversity spore-forming bacteria by analysing their genetic variability through molecular approaches. Given that must be preheated to approximately 55 °C before being bactofuged, for comparison, were ...

In this work, pressure-assisted enzymatic gelation was applied to milk proteins, with the goal of enhancing structure and stability pressure-created protein gels. High-pressure processing (HPP) at 600 MPa, 3 min, 5°C concentrate (MPC) samples 12.5% concentration, both in absence presence calf chymosin [up 60 IMCU (international milk-clotting units)/kg milk] or camel (up 45 IMCU/kg milk). Gel ha...

In general, the quality of raw milk and of dairy products has been considerably improved by the refrigeration on farms, and in processing plants. Unfortunately, the current practices for the collection and the storage of the raw milk favour the growth of psychrotrophic bacteria, able to grow below 7°C, regardless of their optimal growth temperature. Besides their rapid growth ability in refrige...

BACKGROUND The somatic cell count (SCC) is commonly used to monitor udder health and diagnose subclinical intramammary infection (IMI) in dairy cattle. HYPOTHESIS The Somaticell test (ST) and California mastitis test (CMT) are clinically useful cow-side tests for diagnosing subclinical IMI. ANIMALS One hundred and eleven dairy cows at dry-off and 92 cows within 4-7 days postcalving. METHO...
