OBJECTIVES Preterm infants are often fed pasteurized donor milk or mother's milk that has been stored frozen for up to 4 weeks. Our objectives were to assess the impact of pasteurization or prolonged storage at -20 degrees C on the immunologic components of human milk and the capability of the different forms of human milk to support bacterial proliferation. MATERIALS AND METHODS The concentr...

as milk is a liquid compound, it needs containers at every stages of movement. the first significant development in milk packaging created at the end of nineteenth century. the flavor changes and shelf life of pasteurized milk and ultra pasteurized milk are affected by processing conditions, packaging materials and microbial growth. off-flavor is an effective factor on reduction of milk quality...

Introduction Brucellosis is a worldwide zoonosis that causes much clinical morbidity as well as considerable loss of productivity in animal husbandry. It has been present for millennia and has managed to elude eradication even in most developed countries1.Transmission of brucellosis to humans occurs through the consumption of infected, un-pasteurized animal products, through ruptures in skin/mu...

introduction: recently, consumers have directed their interest towards low fat products as they associated them with a reduced risk of well-known health problems such as obesity and coronary heart diseases. fat is a multifunctional ingredient in ice cream system. thus, in attempts to provide desirable flavor and physical characteristics of full fat ice cream, manufactures looking for fat replac...

Sixty pasteurized milk samples were collected aseptically from different processing dairies and analyzed for total viable count and aerobic spore count. Bacillus subtilis was found to be the predominant aerobic spore former (33.33%) followed by B.megaterium (24.44%), B.licheniformis (17.77%), B.cereus (8.88%), B.coagulans (6.66%), B.pumilus (4.44%), B.sphaericus (2.22%), and B.circulans (2.22%)...

Fifty nine samples of raw milk, 60 samples of pasteurized milk, 24 cream, 39 butter, 27 curd, 19 peda, 21 paneer and 20 skim milk powder samples were analyzed for the presence of different Bacillus species and a total of 182 isolates were obtained. The isolates were identified as Bacillus subtilis (51), Bacillus megaterium (39), Bacillus cereus (28), Bacillus licheniformis (32), Bacillus coagul...

In a prospective case-control study of sporadic Salmonella Enteritidis infection in Denmark (1997-1999), foreign travel was reported by 25% of 455 case patients and 8% of 507 controls (odds ratio (OR) = 3.7, 95% confidence interval (CI): 2.4, 5.5). Among nontravelers, 80% of 335 cases and 81% of 467 controls had consumed eggs or dishes containing raw or undercooked eggs during the week before d...

Six direct plating media were evaluated for their suitability to recover uninjured, heat-injured, and freeze-injured cells of four strains of Listeria monocytogenes from four foods. Cells were inoculated into foods to achieve ca. 10(2) to 10(3), 10(4) to 10(5), or 10(5) to 10(6) viable cells per ml or g (low, medium, and high populations, respectively). No appreciable differences in recovery of...

The use of donor human milk is increasing for high-risk infants, primarily for infants born weighing <1500 g or those who have severe intestinal disorders. Pasteurized donor milk may be considered in situations in which the supply of maternal milk is insufficient. The use of pasteurized donor milk is safe when appropriate measures are used to screen donors and collect, store, and pasteurize the...
