Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...

OBJECTIVES This manuscript describes the development, validation and clinical application of a novel method for the quantification of the antiretroviral drug efavirenz in dried breast milk spots using LC-MS. METHODS Dried breast milk spots were prepared by spotting 30 μL of human breast milk on each circle of Whatman 903 Protein Saver cards. Chromatographic separation was achieved on a revers...

Infant feeds made up from dried milk are known to be hazardous if the mixture is too concentrated. Tests with five commercial brands of dried milk showed that nurses, midwives, and mothers often made up feeds incorrectly; in most cases the amount of powder used was excessive.Fewer mistakes would be made if scoops were standardized or, better, if the milk was made up in small, accurately weighed...

Case 1. She was the tenth-born in her family and weighed 2.75 kg. (6 lb.) at birth. She also was fed on Ostermilk No. 2, reconstituted as follows: 2* measures Ostermilk No. 2+3* measures water+ 1 teaspoonful of sugar, four-hourly. Her initial sodium level was 194 mEq/l., potassium 7.1 mEq/l., and chloride 156 nIEq/l. The carbon dioxide combining power was 17 mEq/l., and the blood urea nitrogen ...

Nonfat dry milk (NDM) and powdered whey beverages are available at the retail level, packaged in No. 10 cans in a reduced oxygen atmosphere to prolong shelf life. The objective of this research was to determine the sensory and nutritional quality of these dried milk products at the time of purchase. In the 10 brands tested, wide variation existed in headspace oxygen, can seam quality, sensory q...

Samples of maternal and foetal blood and of human milk, cow's milk, and dried cow's milk have been analysed for cobalamins by chromatography and bioautography. Plasma cobalamins in late pregnancy and after delivery differed quantitatively from those in healthy non-pregnant women. Differences in the proportions of plasma cobalamins were also observed between mothers and their newborn infants. Th...

In a previous communication (1) an experimental method for drying breast milk by a modification of the Just-Hatmaker roller process was presented. It had long been felt that could human milk be preserved in some way another step forward towards the solution of the nutritional problems of infancy would be provided (2). It was found that the drying of the milk was entirely practicable and a powde...
