Starch is obtained naturally through extraction from the grain or root of cassava, a root vegetable. It is often commercially sold in the form of a dry powder and its grade varies based on the type of application it is being used for. However, often it is used in the food industry due to the lack of certain properties that are needed in other industries.
Production of tapioca starch can be separated into 3 different stages, namely preparation and extraction, purification and water removal. In the preparation and extraction process, the cassava roots are washed and peeled, whereby the pulp is strained with the addition of water. Subsequently, purification of the extracted starch is carried out using the process of sedimentation and centrifugation. The last stage involves the removal of water which is carried out through drying.
Adhesive and Glue Industry
Tapioca Starch is popular in the adhesive industry due to its appreciable binding capacity due to its high viscosity sticky properties when mixed with water or certain chemicals.
It is used to reduce manufacturing costs because of its efficiency as a thickener. It is also used to delay the melting of ice cream.
It is used in thread process in order to reduce friction and fraying. It is also used to increase flexibility of the thread generated.
In the paper industry, it is used to increase the elasticity and concentration of the paper before the pulp is pressed into sheets.
