Thickening agent

thickenergelling agentthickening
Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier; in pharmaceuticals as a disintegrant; or as binder in coated paper.
This category includes starches as arrowroot, cornstarch, katakuri starch, potato starch, sago, tapioca and their starch derivatives.

Starch gelatinization

gelatinizationgelatinizedgelatinize
Starches may be modified to increase their stability against excessive heat, acid, shear, time, cooling, or freezing; to change their texture; to decrease or increase their viscosity; to lengthen or shorten gelatinization time; or to increase their visco-stability.
The gelatinization temperature of starch depends upon plant type and the amount of water present, pH, types and concentration of salt, sugar, fat and protein in the recipe, as well as starch derivatisation technology are used.

Starch

starcheswheat starchrice starch
Modified starch, also called starch derivatives, are prepared by physically, enzymatically, or chemically treating native starch to change its properties. Acid-treated starch (INS 1401), also called thin boiling starch, is prepared by treating starch or starch granules with inorganic acids, e.g. hydrochloric acid breaking down the starch molecule and thus reducing the viscosity.
A modified starch is a starch that has been chemically modified to allow the starch to function properly under conditions frequently encountered during processing or storage, such as high heat, high shear, low pH, freeze/thaw and cooling.

Spray drying

spray-driedspray driedspray drier
Drying methods to make starches cold-water-soluble are extrusion, drum drying, spray drying or dextrinization.
A substance to be encapsulated (the load) and an amphipathic carrier (usually some sort of modified starch) are homogenized as a suspension in water (the slurry).

Sodium hypochlorite

Oxidation of starch by sodium hypochlorite, that adds carbonyl and carboxyl groups, is relevant to the production of modified starch products.

Hydroxyethyl starch

In starch industry, acetic anhydride is a common acetylation compound, used for the production of modified starches (E1414, E1420, E1422)

Yogurt

yoghurtdahicurd
A suitably modified starch is used as a fat substitute for low-fat versions of traditionally fatty foods, e.g. industrial milk-based desserts like yogurt or reduced-fat hard salami having about 1/3 the usual fat content.
Some yogurts contain added modified starch, pectin (found naturally in fruit), and/or gelatin to create thickness and creaminess artificially at lower cost.

Textile printing

Carboxymethylated starches are used as a wallpaper adhesive, as textile printing thickener, as tablet disintegrants and excipients in the pharmaceutical industry.
Today, modified carboxymethylated cold soluble starches are mainly used.

Genetically modified food

genetically modified foodsgenetically modifiedGM food
Modified starch should not be confused with genetically modified starch, which refers to starch from genetically engineered plants, such as those that have been genetically modified to produce novel fatty acids or carbohydrates which might not occur in the plant species being harvested.
Starch can be further modified to create modified starch for specific purposes, including creation of many of the sugars in processed foods.
