Abstract
The invention relates to a method for producing starch networks. The method may include preparing a basic starch and preparing a networking starch. The method may further include manufacturing an initial product including the basic starch and the networking starch, and processing the initial product to yield the starch networks, such that the starch networks are at least partially heterocrystallized.

A method for producing starch networks comprising:
- preparing a basic starch;
- preparing a networking starch;
- manufacturing an initial product including the basic starch and the networking starch;
- and
- processing the initial product to yield the starch networks, such that the starch networks are at least partially heterocrystallized.
A method for producing starch networks from a networking starch fluid, containing a basic starch and a networking starch, comprising:
- preparing the basic starch and the networking starch together;
- and
- processing the networking starch fluid directly to yield the starch networks, the starch networks being at least partially formed by heterocrystallization.
A starch network having, at a relative air humidity greater than 70%, a modulus of elasticity greater by at least a factor of 2, compared with a similar thermoplastic starch (TPS), said starch network being not sticky over a range of 0% to 100% relative humidity, and being almost completely soluble in water, said starch network having a strength in a range of 0.5 mPa to 5 mPa after swelling in water at 22° C., and said starch network being transparent.
An initial product, including a softener content greater than 30%, said initial product including a networking starch and a basic starch, said initial product being configured to produce starch networks, which are at least partially formed by heterocrystallization, the initial product being in a storable and transportable form, as one of a film, a foil, a powder, a spray-dried powder, a freeze-dried powder, a granule, and a pellet.
