Product Samples
Thirteen samples of commercial cornflakes were purchased from local
stores and used before optimal consumption deadline. They were given a code
name and their basic composition, given by the manufacturer, is reported in
Table 1. These samples encompass a variety of ingredients and processes from
which differences in physical and sensorial properties are expected. In the
following, the word “sample” means sample from one brand. Their moisture
content was determined by the standardized Chopin method applied to maizebased
food products: weighing before and after 4 h at 130
Cornflakes size distribution was measured by sifting 100-g bulk flakes,
before and after partial compression, with decreasing mesh superimposed
grids: 10, 5, 2 and 1 mm. The results were expressed by the mass fraction of
each particle size interval to the total mass before and after compression. The
apparent density was assessed by weighing 100-mL bed of flakes before and
after compression, in a calibrated 250-mL beaker after gentle shaking.
