Tapioca Starch is isolated from the tuberous roots of the manioc plant, which grows mainly in equatorial climates. Depending on the region of growth, plants may be known as mandioca, yucca, cassava or tapioca. Tapioca is the seventh largest production of staple food in the world. Among the starchy staples, Tapioca gives a carbohydrate production which is about 40% higher than rice and 25% more than maize with the result that Tapioca is the cheapest source of calories for both human nutrition and animal feeding.
There are many varieties of Tapioca, but they fall into two main categories named bitter (Manioc palmate) and sweet (Manioc aspic). For industrial purposes mostly bitter variety is used because of higher starch content. Sweet tapioca is used for food because of taste and its dough forming ability.
Starch makes up the nutritive reserves of Tapioca plant. During the growing season solar energy is transported as sugar solution down to the tubers and sugar is converted to starch in the form of tiny granules occupying the most of the cell interior. The conversion takes places by means of enzymes. Tapioca Starch is a food grade product refined from tapioca roots. It is typically used as a native water binding and texturizing agent.
Tapioca Starch, in cooked dispersion, is quite clear and bland in flavor. The texture is long and somewhat stringy. Upon cooling, it may set to soft gel. Under prolonged heating, and under acidic conditions, the starch will lose most of its thickening ability.
Tapioca Starch is recommended for use in extruded snacks for improved expansion. It can also be used in custard-type pie filling to reduce surface cracking. Additionally, it may be used as a thickener in "all natural" foods that are not subject to rigorous processing conditions. Tapioca Starch, which is very bland in flavor, is used in processed baby foods as a bodying agent.
Tapioca starch is widely used in making foods, baby food, bread, instant noodle,noodle,seasoning.
Glucose, lactose and fructose made from tapioca starch are used as substitutes for sucrose in beverages, jams and canned fruits.
Tapioca starch is used to mix with active pharmaceutical materials to make capsules and tablets.
Tapioca starch is used in 3 stages of textile processing:
■ the sizing stage to make yarn smooth
■ the printing stage to make the colors even and the finishing stage to make the colors even
■ the finishing stage to make the fabric durable and shiny.
Tapioca is one of the ingredients for animal compounding.
Tapioca starch is used in the stage of paper pressing and the stage of flattening and polishing to improve the quality of the paper. It is also used to thicken some kinds of paper, such as calendar paper and package paper.
Tapioca starch is a very important raw material in making glues.
Tapioca starch can be used as a substitute to plastic to mix with bio-degradable polymer to produce a packaging material.
