Tapioca Starch Industrial Grade
NATIVE TAPIOCA STARCH
Food Grade & Industrial Grade
Native tapioca starch, derived from the cassava root, is a versatile carbohydrate used in various industries. It comes in two primary grades: industrial and food grade.
Industrial-grade Native Tapioca Starch
This grade of tapioca starch is used in non-food applications. Its properties make it valuable for a range of industrial processes, including:
1. Paper and Textile Industries: It acts as a binder and stiffening agent, improving the quality and durability of paper and textile products.
2. Adhesives: Used in the formulation of glues due to its strong adhesive properties.
3. Construction: Helps in the manufacture of gypsum boards and other construction materials.
4. Biodegradable Products: Used in producing biodegradable plastics and other eco-friendly materials.
Food Grade Native Tapioca Starch
Food grade tapioca starch is processed to meet safety standards for consumption and is used in various food applications:
1. Thickening Agent: Commonly used in sauces, soups, and gravies to provide the desired consistency.
2. Stabilizer: Helps maintain the texture and structure of foods like dairy products, processed meats, and bakery items.
3. Gluten-Free Baking: A popular ingredient in gluten-free recipes, providing elasticity and moisture retention.
4. Sweeteners: Used in the production of sweeteners like glucose and fructose syrups.
Key Differences Between Industrial and Food Grades
Purity and Safety: Food grade starch is subject to stringent regulations to ensure it is safe for consumption, free from harmful contaminants. Industrial grade starch does not need to meet these standards and may contain impurities not suitable for ingestion.
Processing: Food grade starch undergoes more refined processing to remove any non-food-safe elements, whereas industrial grade starch may be processed with different chemicals or methods more suited for non-food applications.
Applications Overview
Industrial Grade: Paper and textiles, adhesives, construction, biodegradable products.
Food Grade: Thickening and stabilizing in food products, gluten-free baking, sweetener production.
Modified tapioca starch industrial grade encompasses various types of tapioca starch that have been chemically or physically altered to improve their properties for specific industrial applications. These modifications enhance the starch’s performance in different processes and end products. Here are the primary types of modified tapioca starch in industrial use:
1. Cationic Starch
Cationic starch is modified by introducing positively charged groups into the starch molecules. This alteration improves the starch’s affinity for negatively charged surfaces, making it particularly useful in the paper and textile industries. In paper manufacturing, cationic starch is used to improve paper strength, retention of fillers, and drainage. It also enhances the surface properties, leading to better printability and reduced ink bleed.
2. Sizing Starch
Sizing starch is used primarily in the textile and paper industries to provide a protective coating or to modify the surface properties of fibers and papers. In textiles, sizing starch improves the strength and abrasion resistance of yarns during weaving. In paper production, it helps to increase the stiffness and resistance of paper to water and oils. This type of starch is often applied during the wet end of the paper manufacturing process or as a surface treatment.
3. Spray Starch
Spray starch is a form of modified starch applied to fabrics and paper using a spraying process. In textiles, it is used to give fabrics a crisp finish and to make ironing easier. For paper, it is sprayed onto the surface to improve smoothness, printability, and to enhance the overall quality of the final product. This type of starch is often pre-gelatinized to make it easily dispersible in water and suitable for spray application.
4. Oxidized Starch
Oxidized starch is produced by treating starch with oxidizing agents such as sodium hypochlorite. This process reduces the molecular weight of the starch and introduces carboxyl groups, making it more soluble in cold water and giving it better film-forming properties. Oxidized starch is used in the paper industry to improve paper strength, in the food industry as a thickener, and in adhesives for better bonding performance.
Applications in Various Industries
Paper Industry: Modified tapioca starch is used to enhance the strength, printability, and durability of paper products. Different modifications cater to specific needs, such as internal sizing, surface sizing, and coating.
Textile Industry: It is used for warp sizing to protect yarns during weaving, improve the finish of fabrics, and aid in dyeing processes.
Food Industry: Certain modified starches, like oxidized starch, can be used as thickeners, stabilizers, and texturizers in various food products.
Adhesive Industry: Modified starches serve as binders in adhesive formulations, providing better bonding and stability.
In summary, modified tapioca starch industrial grade varieties like cationic starch, sizing starch, spray starch, and oxidized starch are tailored to meet the specific requirements of various industrial processes, enhancing performance and efficiency in applications ranging from papermaking to textiles and adhesives.
