| 英文摘要 | The kinetic process of pressure-induced gelation of whey protein isolate (WPI) solutions (20-28%, w/v) was studied using in situ light scattering. The gelation of WPI solutions could be induced by pressurization at 250 MPa, a pressure lower than that reported in other studies. The gelation time decreased with increasing WPI concentration and followed an exponential rule. The relationship of the logarithm of scattered light intensity (I) versus time (t) was linear after the induced time and could be described by the Cahn-Hilliard linear theory. With increasing time, the scattered intensity deviated from the exponential relationship, and the time evolution of the scattered light intensity maximum I(m) and the corresponding wavenumber q(m) could be described in terms of the power-law relationship as I(m) similar to t(beta) and q(m) similar to t(-alpha), respectively. These results indicated that phase separation occurred during the gelation of WPI solutions under high pressure. (C) 2009 Elsevier Ltd. All rights reserved. |
