Effect of spry drying, high pressure and UV radiation in the quality of human milk
Ariana Rodríguez Arreola and Adriana Cavazos Garduño
CUCEI-University of Guadalajara, México
M
any studies have proved that human milk is the ideal food to feed children during the first six
months of life, complementing their feeding with other more complex foods up to two years.
But there is the problem of those children whose mothers cannot feed them for some reason beyond
their control. For this, it has begun the transformation of mother's milk in powder treated with High
Pressures (HP) and UV radiation; with the purpose of supplying human milk Banks in Mexico. It is
essential to know if this change allows human milk to conserve its nutritional properties, it is also
important to know if the shelf life of the product allows it to compete in quality with the big companies
that make formulations of cow's milk powder for babies. The results obtained over the course of 10
weeks have shown that there is no significant loss in the protein and carbohydrates content of the spray-dried human milk powder
relative to fresh human milk (p>0.05). Microbiological analyzes performed after high pressure treatment and spray drying did not
show growth in standard count, dextrose and Macconkey agar, except in MRS agar ≤12 UFC; treated with UV radiation there were
growth in standard count, potato dextrose, and MRS agar. The results allow to continue with the transformation of the human milk
powder and know which treatment is the best for it conservation.
