2.7. Apparent viscosity
A controlled-shear rate rheometer (AR-G2, TA instruments;
Newcastle, USA) with a cone-and-plate geometry (gap ¼ 55 mm;
cone diameter, 40 mm; cone angle, 2) was used to determine the
apparent viscosity (happ) of SB. The apparent viscosity was registered
after increasing the shear rate from 0.1 to 30 s1 for 100 s.
Temperature was controlled at 21.0 C with a water bath (Julabo
ACW100, Julabo Labortechnik; Seelbach, Germany) associated to
rheometer. For all freeze-thawed, highly-destabilized soy beverages,
this assay was discarded to avoid sampling errors.
