Some experiments quantified diffusivity constants of glucose
and sucrose from alginate gels to water, which are 2.55 1010
at 5 C for glucose and from 2.85 1010 to 4.13 1010 m2/s at
5 to 20 C, for sucrose. From agar gels to water diffusivity constants
are in the same range of magnitude at 2.47 1010 m2/s at 5 C
(Friedman & Kraemer, 1930). Moreover, Schwartzberg and Chao
(1982), determined diffusivity constants of glucose, fructose and
sucrose to water at 25 C from 0.69 109 to 0.54 109 m2/s.
