At
the first stage, phases are subject to separation, as a result
of which the solid phase of a polymer forms a net-like structure
which binds the liquid phase in its meshes. At the second
stage, double helices of amylose are formed in the polymer
phase. The amylose gel occurs as a microporous
structure made of threads, 10–30 nm in diameter. They are
composed of joint segments of amylose chains, with a degree
of polymerization ranging from 26 to 73, appearing in
the form of double helices.
