カゼインフォスフォペプチド給与がラットのミネラル代謝に及ぼす影響

抄録

Effect of casei叩 hosphopeptide (CPP) on mineral metabolism was investigated in rats.Animals were fed a control diet (CPP 0%) or CPP diets (CPP 0.1, 0.3, 0.5%). All diets contained the same amounts of calcium (0.4% ) , phosphorus (0.8% ) and zinc (10.5mg/kg). Though an increase in the calcium retention was not observed, the deposition of calcium in a femur was greater in the CPP diet groups than those in the control diet group. Apparent absorption and retention of zinc were greater in two of the CPP diet groups (0.3, 0.5%). Apparent absorption and retention of iron were greater in the 0.5% CPP diet group. Apparent absorption and retention of copper were greater in the all CPP diet groups. These results suggest that CPP supplementation may have a significant effect on the absorption of trace elements.
