Evaluating the protein digestive stability with in vivo models should be more objective. The present study aimed to verify the in vivo digestibility of soybean β-conglycinin β-subunit in Wuzhishan （WZS） minipigs. Three minipigs were surgically fitted with O-stomach and T-ileum cannulae and fed with soybean meals. According to SDS-PAGE, the 50 kD fraction of soybean β-conglycinin β-subunit persisted in the gastric fluid until 6 h after feeding, which was detected at 3 h and clearly visible at 4-6 h in the intestinal fluid. Western blot with anti-β-conglycinin β-subunit McAb confirmed it.展开更多
