The remaining
water was boiled and added to the heavy slurry and
blended at high speed for 1 min to form light slurry. A
commercial juice extractor was used to extract the soy
beverage from the slurry. The slurry was poured into
the extractor, the soy beverage was collected, and the
okara (grit) was re-centrifuged to extract the remaining
soy beverage. The volume of soy beverage was measured
to determine the beverage yield per kg soybean
seed protein.
