Maintenance of genome stability by preventing DNA damage is crucially important for counteracting carcinogenesis and age-associated diseases. The levels of niacin, vitamin E, vitamin B12, folate, β-carotene, retinol, magnesium, calcium, selenium and zinc, which are key micronutrients considered to be important in the prevention of genome damage, were measured in a range of fresh and processed f...

Two mutants with increased protease production were isolated after nitrosoguanidine treatment of Staphylococcus aureus 8325N. The wild type produces low amounts of extracellular proteolytic activity. The enzyme was inducible and could only be detected if casein or preferably skim milk powder was used as inducer. The optimal pH, salt concentration, and media for enzyme production were determined...

The r61e of choline in the nutrition of the young rat has been studied extensively (14). Sure (5) has also shown the need of choline for lactation in mature animals. Its relation to the nutrition of the chick has not been studied, although Abbott and DeMasters (6) concluded that the addition of choline to a skim milk powder-polished rice ration increased egg production and decreased mortality i...

1. The effect of different protein sources in milk-substitute diets on abomasal acidity and proteolytic activity was studied in Friesian calves, aged 20-58 d (Expt 1). The diets contained 'mildly' preheated, spray-dried skim-milk powder (MHM), severely preheated, spray-dried skim-milk powder (SHM), fish-protein concentrate (FPC) or solvent-extracted soya-bean flour (SF) as the main protein sour...

Low numbers of salmonellae in a dried skim milk sample that was implicated in an outbreak of salmonellosis grew rapidly upon rehydration and incubation.

To detect urea content in milk powder, a nonlinear chemical fingerprint technique was developed. In our study, Belousov-Zhabotinsky oscillatory chemical reaction (B-Z) was performed using milk powder and malonic acid as main dissipative substances. The same dosage of milk powder with or without artificially added urea was introduced to “H+ + Ce4+ + 3 BrO − + malonic acid” oscillating system, re...

OBJECTIVE To compare the overall nutrient intake of American children (ages 2 to 19) who exclusively use skim milk instead of 1%, 2%, or whole milk; lean meats instead of higher-fat meats; or fat-modified products instead of full-fat products. STUDY DESIGN A unique sorting procedure was used to categorize respondents to the 1989-1991 Continuing Survey of Food Intake by Individuals according t...

This work aimed to establish an integrated approach investigate the total phenolic content and antioxidant activities of dried skim camel cow milk their fractions. The fractions were obtained by acid or enzymatic coagulation followed spray drying (inlet temperature/outlet temperature: 125 ± 2 °C/90 °C) freeze (−50 °C, 0.05 mbar) coupled not gamma irradiation (at 5, 11, 22 kGy). results showed t...
