Introduction to Vietnam Modified Tapioca Starch
What is Modified Tapioca Starch?
Modified tapioca starch is a highly adaptable and commonly used food ingredient that has become popular with consumers globally. Extracted from cassava, a root vegetable native to Vietnam, this starch undergoes modification through physical, chemical, or enzymatic methods to improve its functional properties. Renowned for its excellent thickening and stabilizing capabilities, it is an essential ingredient in a variety of food applications. Additionally, it finds use in other industries such as paper, adhesive and textiles.

Why to Modify Native Tapioca starch
The need to modify native tapioca starch stems from its inherent limitations in various applications. Extracted from the root of the cassava plant, native tapioca starch has characteristics that make it cannot match for requirements of certain food and industrial uses.
Firstly, native tapioca starch has relatively low viscosity, which may not provide the desired thickening or binding effect in certain recipes or manufacturing processes.
Secondly, the modification process can enable the starch to dissolve in water at the specific temperature required by the customer’s recipe.
Additionally, native starch’s limited stability under high temperatures can lead to texture and sensory issues in food products. Modifying tapioca starch addresses these limitations, enhancing its functionality across a wide range of applications.
The modification of tapioca starch aims to overcome these limitation.
How to Modify Tapioca Starch
Enhancing the functionality and versatility of tapioca starch for various applications is achieved through its modification. There are multiple methods to modify tapioca starch, each imparting unique characteristics and properties tailored for specific uses.
One widely used technique is physical modification, involving processes such as heating, cooling, and drying. In the tapioca industry, alpha starch is a type of physically modified starch that undergoes high-temperature processing with water before being dried to produce the final starch product.
Chemical modification is another common method where chemical agents alter the starch molecule, resulting in improved functionalities like increased stability, resistance to high temperatures, and enhanced emulsifying capabilities.
Lastly, enzymatic modification is a more natural method that employs specific enzymes to break down and modify the starch molecule. This leads to better digestibility, a lower glycemic index, and improved nutritional properties. Understanding these various methods of modifying tapioca starch allows businesses and individuals to choose the most suitable type of starch for their specific needs and applications.

Physically-modified cassava starch
Physically modified tapioca starch involves altering tapioca starch through processes like heating, cooling, drying, and grinding. This method enhances the starch’s functionality and versatility, making it suitable for various food industry applications.
A common example of physically modified tapioca starch is pregelatinized starch, also known as alpha starch.

Chemically-modified cassava starch
Another approach to modifying tapioca starch involves chemical processes. Types of chemically modified tapioca starch include hydroxypropylated starch, acetylated starch, and cross-linked starch. These modifications change the starch’s physical and chemical properties, enhancing stability, texture, and thickening abilities.
Examples of chemically modified tapioca starch are:
- Acetylated Starch (E1420)
- Distarch Phosphate (E1412)
- Oxidized Starch (E1404)

Dual-modification tapioca starch
In addition to chemically modified starch, dual-modification tapioca starch is another important variant. This type of starch undergoes further modifications to significantly improve its properties, resulting in increased resistance to heat, acidity, and mechanical shearing.
Examples of dual-modified tapioca starch include:
- Acetylated Distarch Phosphate (E1414)
- Acetylated Distarch Adipate (E1422)

Vietnam common modified tapioca starch
In addition to being a leading producer of native tapioca starch, Vietnam is also well-known for its high-quality modified cassava starch. This makes Vietnam an ideal source for bulk purchases of tapioca starch. Recently, the demand for modified tapioca starch from Vietnam has seen significant growth.
Here are some of the most common types of modified tapioca starch in Vietnam:
Pregelatinized starch (Alpha starch)
Alpha physically modified starch is a type of starch that undergoes high-temperature processing with water before being dried to create the final product.
This starch dissolves readily in water at low temperatures, producing a transparent and viscous solution. It can also form a gel as the temperature increases, which is beneficial for creating gel structures in food and pharmaceutical products.
Common applications include: Food, animal feed, and adhesives.

Acetylated starch (E1420)
Acetylated Starch (E1420), also known as Starch Acetate (INS1420), is a modified tapioca starch obtained by esterifying native cassava starch with acetic anhydride or vinyl acetate. This process substitutes hydroxyl groups with acetyl esters, creating a distinctive molecular structure that enhances the starch’s thermal and stability properties.
This modification enhances the starch’s ability to withstand heat and improves its durability in food and industrial applications.
Common Applications: Primarily used in the food industry, including noodles, frozen food products, snacks, confectionery, and dairy products (such as yogurt).

Distarch phosphate (E1412)
Modified tapioca starch E1412, known as Distarch Phosphate or cross-linked starch, is a modified form of cassava starch renowned for its stable molecular structure and enhanced attributes in the food industry. This starch variant is considered a safer substitute for toxic borax.
Distarch Phosphate derived from tapioca also demonstrates enhanced viscosity and stability due to its unique molecular arrangement.
Common Applications: Predominantly used in the food industry, including in products such as meat items (sausages, meatballs, ham), gummy candies, sauces, and canned foods.

Acetylated distarch phosphate (E1414)
Modified tapioca starch E1414 (Acetylated Distarch Phosphate) is derived from food starch through esterification and cross-linking methods, using substances such as vinyl acetate or phosphorus oxychloride.
Common Applications: Primarily used in the food industry, pharmaceuticals, and cosmetics.

Acetylated distarch adipate (E1422)
E1422 Acetylated Distarch Adipate is created by treating native cassava starch with adipic anhydride and acetic anhydride, yielding a white powder that enhances stability under high temperatures. This dual-modified tapioca starch combines the characteristics of acetylated starch and cross-linked starch. This modification significantly enhances the stability of tapioca starch.
Common Applications: Predominantly used in the food industry, including various sauce types (such as ketchup, chili sauce, and mayonnaise), meat products, dairy foods (like yogurt and chocolate milk), and confectionery.
