The effect of cold storage (5 C, 24 h) and heat treatment (60 C, 5 min) of milk on activities of free and membrane-bound xanthine oxidase has been studied. Both treatments enhanced total xanthine oxidase activity in milk. Activity of membrane-bound xanthine oxidase increased and free xanthine oxidase decreased in buttermilk while it increased in skim milk on cold storage. Heat of milk increased...

Bifidobacterium longum was microencapsulated by extrusion technique and added in fresh milk tofu and pineapple juice. Microencapsulation of B. longum with Eleutherine americana extract, oligosaccharides extract, and commercial fructo-oligosaccharides was assessed for the bacterial survival after sequential exposure to simulated gastric and intestinal juices, and refrigeration storage. Microenca...

In most of the world’s population the ability to digest lactose declines sharply after infancy. High lactose digestion capacity in adults is common only in populations of European and circumMediterranean origin and is thought to be an evolutionary adaptation to millennia of drinking milk from domestic livestock. Milk can also be consumed in a processed form, such as cheese or soured milk, which...

BACKGROUND Human breastmilk provides the best nutrition for infants. When women or infants have difficulties in breastfeeding directly, breastmilk is usually pumped and frozen for later use. However, while frozen, breastmilk may develop a rancid flavor, which induces infant feeding stress and raises the mothers' concerns about the quality of frozen breastmilk. Nevertheless, few studies have inv...

To gain a better understanding of the factors involved in textural changes in Mozzarella cheese during storage, electron microscopic imaging was used to compare the ultrastructure of the protein matrix on the day of stretching (0 weeks) and after 6 weeks of storage at 4°C. Low-fat and full-fat cheeses were prepared from nonhomogenized milk and from milk homogenized at 10.3 and 17.2 MPa. Analysi...

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...

Milk is a key component in infant nutrition worldwide and, in the Western parts of the world, also in adult nutrition. Milk of bovine origin is both consumed fresh and processed into a variety of dairy products including cheese, fermented milk products, and infant formula. The nutritional quality and processing capabilities of bovine milk is closely associated to milk composition. Metabolomics ...

Background: Listeria monocytogenes is the causative agent of listeriosis, a highly fatal opportunistic food borne infection. Listeriolysin O is a major virulence factor in this bacterium, which is encoded by hlyA. The aim of the present study was to determine the relation of Listeria monocytogenes hlyA gene isolated from fresh cheese with habitual abortion in Marvdasht. Materials and methods: I...

Keenan McRoberts Problem Articulation: Communities in the Gavilanes River micro-watershed of Veracruz, Mexico’s highlands face numerous challenges to make traditionally subsistence agricultural livelihoods more competitive in a dynamic market environment. Specialized goat cheese production in Veracruz’ rural highland communities could provide an opportunity to increase household profits. Commun...
