The goals of this study were to determine L-ascorbic acid concentrations in various milk products, and to evaluate the effect of storage time on L-ascorbic acid in milk. Commercial plain milk samples were obtained from either a raw-food market or a supermarket, in Mae Hia, Mueang District, Chiang Mai Province, Thailand, during July, 2008. The types of milk were separated based on fat percentage...

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...

Isolation of amplifiable genomic DNA is a prerequisite for the genetic assessment of diseases and disease susceptibility in farm animals. Milk somatic cells are a practical, animal friendly and cost-effective source of genomic DNA in milking ruminants. In this study, six different DNA extraction methods were optimized, evaluated and compared for the isolation of DNA from ovine milk samples. Met...

Whereas many differential leukocyte count methods for high somatic cell count (SCC) milk from mastitic cows are available, only a few have been developed for low SCC milk. We have developed a flow cytometric differential leukocyte count method for low SCC milk. The procedure consists of 1) 1.5 ml of diluted milk sample (30%, vol/vol dilution with PBS), 2) centrifugation, 3) leukocyte labeling w...

Background: Lactoperoxidase (LPO) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. The aim of this study was to provide information on activity and thermal inactivation behavior of LPO in Iranian cow and buffalo milk and whey. Methods: Sixty cow and buffalo milk samples were collected. The LPO activity was measured using ...

Growing clinical evidences indicate the benefits of human milk (HM) for appropriate growth and development of a newborns: the particular composition make it a unique and inimitable nutrient [1]. Mother’s own milk is the first choice for all neonates including preterm infants, when it is unavailable or in short supply, donor milk (DM) is an important alternative. DM should be provided from an es...
