Milk proteins and iron absorption: contrasting effects of different caseinophosphopeptides.

Clusters of phosphoserine residues in cow milk caseins bind iron (Fe) with high affinity. Casein inhibits Fe absorption in humans, but protein hydrolysis lessens this effect. Phosphopeptides from different caseins gave conflicting results on Fe absorption; release of phosphate residues by intestinal alkaline phosphatase could be a key point of that metabolism.

Zinc status and bone mineralisation in adolescent girls.

The aim of the project was to assess the relationship between zinc status and bone mineralisation in pre-menarcheal adolescent girls. One hundred and thirty-nine healthy pre-menarcheal girls (Tanner pubic hair stage < or = 4), aged 12.4 +/- 1.

Survival of Listeria monocytogenes After Irradiation Treatment of Camembert Cheeses Made from Raw Milk.

Raw milk camembert cheeses have been inoculated with a pathogenic strain of Listeria monocytogenes (V7 serotype ½ a) and irradiated with gamma or X-rays. The D10 of L. monocytogenes irradiated in cheese was 0.
