Sixteen samples of commercial breakfast cereals were purchased
from Brazilian supermarkets. The samples presented differences
with regard to their grain, sugar and flavor composition. The
samples were firstly submitted to homogenization process by
using a cryogenic mill model MA 775 (Marconi), which works at liquid
nitrogen temperature (196 C). The grinding program consisted
of a 2-min pre-cooling and a 2-min grinding step, followed
by a last 1-min cooling step.
