Breast milk has advantages compared to other milk, including
the temperature of breast milk being the same as body temperature,
cleanliness being guaranteed, and the content of breast milk plays an
essential role in the growth of brain cells and the development of the
nervous system. This study aims to describe the content of protein
levels in breast milk. The samples used in this study were five
samples of breast milk obtained from mothers who had children aged
0-6 months in the Surabaya area, using the Kjeldahl method. The
average protein content of breast milk (is 12.764%). The protein
content of breast milk has a higher protein content in laboratory tests
because it adapts to the needs of the baby. Breast milk has a high
protein content. The protein in breast milk is mostly whey protein
rather than casein. The higher casein content will form relatively
hard lumps in the baby's stomach, making it difficult to digest. The
whey in formula milk contains lactoglobulin, which can cause
allergies in babies. Mothers are expected to follow WHO
recommendations to provide exclusive breastfeeding for 0-6 months
and continue breastfeeding until the child is two years old.
