Estimating the term…
The invention provides a process wherein starch and/or a starch derivative can be gelatinised more efficiently by means a thermo mechanical treatment, when a carbohydrate polymer is used comprising aldehyde containing monomer units which comprise one or more aldehyde groups that are derived from one or more a primary alcohol groups. With this process a granulate or other semi-finished product can be obtained that can be shaped to produce an article that has excellent dimensional stability in water. The invention further provides a granulate, a shaped starch product, a food product or a blown starch film comprising such a carbohydrate polymer.

A granulate of thermoplastic starch that comprises a carbohydrate polymer in an amount in the range of from 3 to 75 weight %, based on total thermoplastic starch, a polyol or urea as plasticizer and water, which carbohydrate polymer comprises aldehyde containing monomer units, whereby at least 1% of the aldehyde containing units have one aldehyde group per monomer unit which one aldehyde group is derived from a primary alcohol group at the C-6 position.
A shaped starch product that comprises thermoplastic starch and a carbohydrate polymer, wherein the carbohydrate polymer is present in an amount in the range of from 3 to 75 weight %, based on total thermoplastic starch, a polyol or urea as plasticizer and water, which carbohydrate polymer comprises aldehyde containing monomer units, whereby at least 1% of the aldehyde containing units have one aldehyde group per monomer unit which one aldehyde group is derived from a primary alcohol group at the C-6 position.
A blown starch film that comprises a thermoplastic starch and a carbohydrate polymer, wherein the carbohydrate polymer is present in an amount in the range of from 3 to 75 weight %, based on total thermoplastic starch, a polyol or urea as plasticizer and water, which carbohydrate polymer comprises aldehyde containing monomer units, whereby at least 1% of the aldehyde containing units have one aldehyde group per monomer unit which one aldehyde group is derived from a primary alcohol group at the C-6 position.
A food product that comprises a food component and a carbohydrate polymer, which carbohydrate polymer comprises aldehyde containing monomer units, whereby at least 1% of the aldehyde containing units have one aldehyde group per monomer unit which one aldehyde group is derived from a primary alcohol group at the C-6 position.
