However, in lot O a “complex emulsion system” was formed as a result of oil addition.
This emulsion could be a twophase system in which oil acted as a phase filler
in the aqueous glucomannan-protein matrix (Damodaran, 1997, chap. 3),
reducing the decrease of WBC, so that pasteurization improved water entrapment ability relative to lot C1.
Pasteurization could therefore have induced some structural rearrangements in lot O,
increasing the hydrophobic interactions in the network; this would enhance
the linking of filler in the biopolymer matrix, thus improving water holding ability
(bonded water) (Kinsella, 1982)
as compared to the control (lot C1). In the case of lot S, the larger number of Na+ and
Cl− ions made for greater electrostatic charge density, which increased the number of
ion–dipole interactions with the permanent dipoles of water, enhancing the water
holding ability of the gel network (lot S1) more effectively than in the control (lot C1).
