| Abstract |
|
Human milk fat is the main energy sourse of the newborn infant. In addition to providing
50% of the total calories in Human milk, fats are essential to normal development because
they provide fatty acids necessary for brain development are an integral part of all cell
menbrance and are the sole vehicle for fat soluble Vitamin and Hormones in milk mature
Human milk has a fat content of 3.0% to 4.5%. Milk fat content and composition change during
lactation. Whereas the triglyceride level rises, the phospholipid and cholesterol concentrations
decrease during the transition from Colostrum to Mature milk.
The author determined Human milk fat concentration during lactation in 68 cases of healthy
lactation woman. Human milk fat fractionation was performed by Total Lipid Reagent and
standard set(sulfo-phosphovanillin method), Triglyceride ABBOTT agent (Enzyme method),
V-Cholestase(NISSUI, Enzyme method), Phospholipids B-Test(Enzyme method) along with
the human milk lipid analysis: Total lipid, Triglycerides, Cholesterol and Phospholipid
were also determined in each sample.The results observed are summarized as follow:
1) The mean levels of Human milk total lipid in Colostrum, Transitional and Mature
milk were 2267±655 mg/dl, 2910±699 mg/dl and 3915±684 mg/dl, respectively.
2) The mean levels of Human milk Triglyceride in Colostrum, Transitional and Mature
milk were 2,246±458 mg/dl, 3,012±580 mg/dl and 3,895±323 mg/dl, respectively.
3) The mean levels of Human milk Cholesterol in Colostrum, Transitional and Mature milk
were 13.5±8.0 mg/dl, 10.7±4.7 mg/dl and 10.16±4.2 mg/dl, respectively.
4) The mean levels of Human milk Phospholipid in Colostrum, Transitional and Mature
milk were 13.5±5.5 mg/dl, 14.3±4.7 mg/dl, respectively.
5) Human milk fat content and composition change during lactation whereas the Total lipid
and Triglyceride levels rises, the Phospholipid and Cholesterol concentration decrease during-
the transition from Colostrum to Mature milk.
6) Korean Human milk has Total lipid content of 2.2 gm/dl to 4.1 gm/dl and almost of
Total lipid consistes of Triglycerides(98.8% to 99.6%).
7) The mean Total lipid levels of urban and rural woman were 4257 mg/dl, 3913 mg/dl,
respectively. The mean Cholesterol levels of urban and rural woman were 11.23 mg/dl,
6.533 mg/dl, respectively.
