Использование

Curdlan is a polymer produced by fermentation from the bacteria alcaligenes faecalis var. myxogenes. it forms a gel when heated in water, initially required to be dispersed and suspended in water since it is insoluble until heated. above 80°c a high-set gel that is irrevers- ible and stable to freezing is formed. a low-set gel is obtained by heating to 55–60°c and then cooling below 40°c; this gel is ther- moreversible. it is capable of gelling over ph range of 2–10. the heat gelling properties allow improved water retention in sausage and ham, improved consistency in oriental-style noodles, and provide viscosity and texture.

Общее описание

Curdlan is an insoluble natural polymer with linear structure mainly produced by Alcaligenes faecalis. It is a dietary fiber with gelatin properties.
