Absence of vitamin D in nonfat dry milk.
American Academy of Pediatrics has strongly e11(lOrsed the use of milk and infant formula lroducts as primary vehicles for vitamin D supplementation to ensure a total vitamin D intake of 400 I. U. per day by all infants and children.12 Although in the United States there are significant regioiial differences with respect to dairy practices in fortifying fluid milk, almost three-fourths of all w...
متن کاملExploring authentic skim and nonfat dry milk powder variance for the development of nontargeted adulterant detection methods using near-infrared spectroscopy and chemometrics.
A multinational collaborative team led by the U.S. Pharmacopeial Convention is currently investigating the potential of near-infrared (NIR) spectroscopy for nontargeted detection of adulterants in skim and nonfat dry milk powder. The development of a compendial method is challenged by the range of authentic or nonadulterated milk powders available worldwide. This paper investigates the sources ...
متن کاملTwenty-four-hour immunofluorescence technique for the detection of salmonellae in nonfat dry milk.
A detection procedure was developed in which a newly devised lysine-iron medium was used as a one-step selective and enrichment medium for detection of salmonellae by the fluorescent-antibody technique. Incubation was conducted in two steps: initially at 30 C for 5 hr to resuscitate sublethally stressed cells, followed by incubation at 39 C for 17 hr. Twenty-seven strains of salmonellae from gr...
متن کاملSerum substitute in epithelial cell culture media: nonfat dry milk filtrate.
A number of milk types and milk fractions were investigated as possible substitutes for serum in cell culture media. A filtrate of reconstituted nonfat dry milk showed promise. Culture fluids containing 5% of the nonfat dry milk filtrate were used to propagate primary and continuous cell cultures, and the cell growth from these cultures was compared with that of cells grown in a serum-containin...
متن کاملCharacterization of Near-Infrared Spectral Variance in the Authentication of Skim and Nonfat Dry Milk Powder Collection Using ANOVA-PCA, Pooled-ANOVA, and Partial Least-Squares Regression
Forty-one samples of skim milk powder (SMP) and nonfat dry milk (NFDM) from 8 suppliers, 13 production sites, and 3 processing temperatures were analyzed by NIR diffuse reflectance spectrometry over a period of 3 days. NIR reflectance spectra (1700-2500 nm) were converted to pseudoabsorbance and examined using (a) analysis of variance-principal component analysis (ANOVA-PCA), (b) pooled-ANOVA b...
