When the slurry was filtered to extract the soy beverage,
approximately two-thirds of the isoflavones partitioned
into the soy beverage, while only one-third
fractionated into the by-product, okara (Table 2). The
protein content of okara was similar to that of soy
beverage and tofu (about 5%) suggesting that a significant
portion of the nutritional content of the soybean is
being lost along with the okara. Therefore, there is a
great potential for utilizing the okara as an animal feed
with a good source of protein and isoflavones. There
was a greater percentage of aglycones (15.4%), glucosides
(28.9%) and acety-genistin (0.89%) in the okara
as compared with the soy beverage (5.41% aglycones,
22.2% glucosides and 0.34% acetyl-genistin) (Table 3),
