실험실에서 제조된 비지는 약 57%의 식이섬유와 20%의 단백질을 함유한 반면, 시판용 비지는 약 59%의 식이섬유와 17%의 단백질을 함유하였다. 비지와 두부의 총식이섬유중 수용성 식이섬유는 3%와 46%를 차지하였다. 비지를 2회 분홰후 사별하고 액체부분을 원심분리한 결과 체위의 비지 식이섬유함량은 58.7%에서 80.6%로 증가되었고 식이섬유회수율은 90.4%이었다. 원심 분리후의 고형물은 46.8%의 단백질을 함유하였고, 단백질의 회수율은 29.2%를 나타냈다. 체위의 비지 지질함량은 처리전보다 훨씬 낮았다.

Tofu-residue (biji) which was made on a laboratory scale from the three U.S. and three Korean soybean varieties contained approximately 57% dietary fiber, 20% protein, while the commercial residue contained 59% dietary fiber and 17% protein. The percent soluble fiber in total dietary fiber were 3% and 46% for residue and tofu, respectively. The tofu-residue was wet milled by blade grinding once or twice, followed by sieving and centrifugation of the liquid fraction. For twice-ground residue, the dietary fiber content increased from 58.70 to 80.6% in the sieved residue, with a fiber recovery of 90.4%. On the other hand, twice-ground centrifuged solids contained 46.8% protein, representing 42.4% of the total protein. Lipid levels in the sieved residue were much lower than in the original residue.
