Native tapioca starch is a natural thickener and binder widely used in the food industry, while modified tapioca starch, enhanced through controlled chemical processes, serves not only the food sector but also industrial applications like paper and textiles, improving the performance of processed foods when added.
What is Native Tapioca Starch?
Native tapioca starch is the unmodified, naturally occurring starch extracted from cassava roots. It is obtained through a simple process of washing, peeling, grating, and separating the starch from the root.
Native tapioca starch is typically white, odorless, and tasteless. It has neutral properties and functions primarily as a thickening agent.
It is commonly used in the food industry as a thickener in products like soups, sauces, and desserts. Native tapioca starch is also favored in gluten-free baking. Its primary role is to provide viscosity and texture to various food items.

What is Modified Tapioca Starch and Why is it Modified?
Modified tapioca starch is derived from native tapioca starch but has undergone chemical or physical modifications to enhance or alter its properties for specific applications.
Modified tapioca starch can be customized to exhibit a wide range of properties. Depending on the modification, it may have improved stability, resistance to high temperatures, acid resistance, and varying degrees of viscosity.
Tapioca starch is modified to improve its performance in various industrial applications. The reasons for modification include:
Enhanced Stability: Modified starches can provide better stability under conditions such as freezing and thawing in the food industry.
Improved Texture: They can be used to modify the texture and mouthfeel of food products like baked goods and processed meats.
Increased Shelf Life: In some cases, modification can extend the shelf life of food products by preventing retrogradation (staling).
Resistance to Acid and Heat: Modifications can make tapioca starch suitable for applications that require resistance to acidic conditions or high temperatures.
Tailored Characteristics: Different modifications result in tapioca starches with specific characteristics, allowing them to meet the requirements of diverse industries such as textiles, adhesives, and pharmaceuticals.
Key Different Between Native Tapioca Starch and Modified Tapioca Starch
Native tapioca starch, in its unaltered state, serves as a valuable natural thickening and binding agent in the food industry, contributing to the texture and consistency of numerous food products.
Conversely, food-grade modified tapioca starch undergoes deliberate chemical enhancements to expand its functional capabilities. This modified starch transcends the confines of the food sector, extending its adaptability to industrial sectors like paper manufacturing and textile production. When utilized as an additive, modified tapioca starch plays a pivotal role in enhancing the performance of processed foods.
Differences in Source
Native tapioca starch is derived from cassava roots through a straightforward extraction and purification process. It's essentially the natural, unaltered starch obtained from the cassava plant.
Modified tapioca starch starts as native tapioca starch but undergoes chemical or physical modifications to alter its properties and enhance its performance in specific applications.
Differences in Properties
Native tapioca starch has neutral properties, meaning it does not undergo any significant chemical modifications during its production. It is typically white, odorless, and tasteless.
Modified tapioca starch can be engineered to exhibit various properties, including improved stability, tolerance to higher temperatures, resistance to acidic conditions, and varying degrees of viscosity.
Differences in Applications
Native tapioca starch is often used as a thickening agent in a variety of food products such as soups, sauces, and desserts. It is also used in gluten-free baking and can be found in some non-food applications like paper manufacturing.
Modified tapioca starch is used in a broader range of applications than native tapioca starch. For example, it's often used in the food industry to provide freeze-thaw stability in frozen products, improve texture in baked goods, and enhance the shelf life of certain food products. It's also employed in non-food industries like textiles, adhesives, and pharmaceuticals.
Differences in Characteristics
It retains its original thickening capacity and clarity and is suitable for applications where a clear or glossy appearance is desired.
The specific modifications can vary, resulting in a range of modified tapioca starches with tailored characteristics, making them versatile for specific industrial needs.
Tapioca Starch Modification Methods
Modified tapioca starch can be altered using various modification methods to enhance its functional properties for specific applications. Here are some common modification methods:

Physical Modification
Tapioca starch can be modified by subjecting it to heat (heat-treatment). This process, known as gelatinization, improves its stability and thickening properties. It's commonly used in applications like pie fillings and sauces.
Chemical Modification
Acetylation: Acetylated tapioca starch is produced by introducing acetyl groups to the starch molecules. This modification increases the starch's tolerance to heat and acid, making it suitable for applications such as instant foods and acidic sauces.
Cross-Linking: Cross-linking involves the creation of covalent bonds between starch molecules. This modification increases the starch's resistance to shear, heat, and acids, making it useful in frozen food products and dairy applications.
Phosphorylation: Phosphorylation involves the addition of phosphate groups to starch molecules. This modification enhances the starch's ability to thicken and stabilize, particularly in acidic conditions, making it ideal for fruit fillings and dairy products.
Esterification: Esterified tapioca starch is created by introducing ester groups to the starch molecules. This modification improves its solubility, making it suitable for instant and convenience food applications.
Oxidation: Oxidized tapioca starch is produced by subjecting the starch to oxidative agents. This modification enhances its stability at high temperatures, making it suitable for baking and other high-heat applications.
Enzymatic Modification
Enzymatic modification involves the use of enzymes to break down and modify the starch molecules. This can result in improved functionality and a range of properties depending on the enzymes used.
Pre-Gelatinization
Pre-gelatinization involves cooking and then drying the tapioca starch. The resulting starch can be easily dispersed in cold water, making it ideal for instant food applications.
Cationization
Cationic tapioca starch is produced by introducing cationic (positively charged) groups to the starch molecules. This modification is often used in the paper industry to improve retention and drainage during paper manufacturing.
E Numbers for Modified Starch
Modified tapioca starch may be identified by E numbers, which are used in the European Union to indicate approved food additives. However, it's important to note that E numbers are not specific to tapioca starch but rather apply to modified starches in general, which can be derived from various sources, including tapioca.
Acetylated Starch (E1420): This starch is created through esterification of food starches using acetic anhydride or vinyl acetate.
Oxidized Starch (E1404): Oxidized starch is produced by treating food starch with sodium hypochlorite.
Distarch Phosphate (INS 1412): Distarch phosphate is obtained by cross-linking starch using sodium trimetaphosphate or phosphorus oxychloride.
Phosphated Distarch Phosphate (E1413): This starch results from esterification and cross-linking of food starch with sodium trimetaphosphate or phosphorus oxychloride, combined with esterification using ortho-phosphoric acid.
Acetylated Distarch Phosphate (E1414): Acetylated distarch phosphate is created through esterification and cross-linking of food starch with sodium trimetaphosphate or phosphorus oxychloride, combined with esterification using acetic anhydride.
Acetylated Distarch Adipate (E1422): This starch is produced by esterification of food starch with acetic anhydride and esterification/cross-linking with adipic anhydride.
Starch Sodium Octenyl Succinate (E1450): Starch sodium octenyl succinate is obtained through esterification of food starch with octenyl-succinic anhydride, followed by neutralization with sodium hydroxide.
Acetylated Oxidized Starch (E1451): This starch is created by treating food starch with sodium hypochlorite and subsequent esterification with acetic anhydride.
