A) Thin Boiling Starch
FABRILOSE is a modified, thin, boiling starch. It has low and uniform viscosity, which does not change much with temperature unlike native starches, which show wide variation in viscosity. The keeping qualities of the native starch also show a marked variation, i.e. considerable degradation occurs on boiling.
Its non-congealing characteristic, shorter boiling time, transparency of paste and lower viscosity ensure easy working, compared to thick boiling starches. Unlike gum and glues which require soaking, FABRILOSE is readily dispersed in water and can be boiled into a smooth paste without any pre-treatment.
One of the main drawbacks of tapioca size is that it thins down very much on boiling, resulting in an uneven pick up on the high speed machine. The viscosity of FABRILOSE does not change with boiling and ensures uniform pick up of size even on modern high speed sizing machines.
Thin boiling starches are manufactured by acid addition to native starch slurry. Low viscosity enables its use in high concentrations without the viscosity getting too high. In some applications, for example in instant soups, thin without any specific technical function. Thin boiling starch non congealing characteristic, transparency and lower viscosity ensure easy working compared to other modified starches. Unlike gum and glues which require soaking, thin boiling starch is readily dispersed in water and can be boiled into a smooth paste without any pre-treatment. Its application in yarn weaving is particularly advantageous as it does not develop abrasive points on over drying and its flexible film gives the yarn the desired elasticity.
B) Oxidized Starch
Oxidized Starch is obtained when Native starch is treated with a variety of oxidizing agents. As compared to native starch, Oxidized starches have shorter chain lengths. It enhances whiteness and eliminates microbiological content. Upon aging, the tendency towards retro-gradation (characteristic of most starches) is eliminated largely due to the presence of functional groups. The outstanding characteristics of oxidized starch is that the pasting results rapidly, at a lower temperature, and the starch paste exhibits a greater degree of fluidity and clarity than that of unmodified starches.
Producing soft- bodied gels of high clarity, oxidized starches are the best thickener for applications requiring gels of low rigidity. This improves adhesion in batters and breading.
Diluted solutions of highly oxidized starches remain clear on prolonged storage, making them suitable for clear, canned soups and transparent confectionery products.
Oxidized starch is also widely used in surface sizing for paper industry which enhances the bonding of loosely attached paper fibers and fillers.
Where primary surface effects are desired, the holding of the paper to a controlled degree is required. This tends to minimize the size penetration for bond paper of good erasure resistance (a fairly tough film of starch upon the surface permits easy erasing of typed letters).
It is widely used for wrap sizing2
