No significant difference in retention was found between vitD3
and 25OD3 in eggs, but the preparation condition affected the degree
of retention (p < 0.05). There was 39% retention of vitD3 and
25OHD3 in eggs heated in the oven for 40 min, significantly different
from 100%. On average the retention in boiled and scrambled
eggs were 82–88% for both vitamers. It was significantly different
from 100% (p < 0.05) for 25OHD3 in scrambled eggs.
