Preparation of spiced milk types extracts.
Freshly harvested maize grains (1 kg) were separated from the
corm and cleaned to remove silk hairs and other extraneous materials. The grains were wet milled into fine paste and filtered through
muslin cloth to obtain the corn milk.
Healthy and unbroken soybean seed were soaked overnight (16
to 17 h) drained and added directly into boiling water. The soybeans were allowed to boil for 15 min after which they were transferred into cold tap water, dehulled and drained. A mass (1.5 kg) of
the seeds were milled. The soymilk slurry was mixed with water and
sieved using muslin cloth to get the filtrate which is soymilk. The
soymilk was boiled for 20 to 25 min and cooled at room temperature to (30 ± 1°C). The filtrate from corn grains and soybeans cotyledon was measured separately in a ratio of 1:3 (corn to soybean).
The mixture was carried out according to the method of Omueti and
Ajomale (2005) slightly modified by the addition of spices (Figure 1).
