Description

Acid Modified Starch is a chemically modified carbohydrate derived from native starch, designed to alter its functional properties for demanding industrial applications. This modification enhances its utility as a highly effective thickener, stabilizer, and binder with tailored viscosity and texture profiles. It is a critical ingredient for manufacturers in the food, paper, textile, and adhesive industries seeking consistent performance and process optimization.

Application

• Food Industry: Used as a thickener, stabilizer, and texturizing agent in sauces, soups, pie fillings, and confectionery products to provide short, non-stringy textures and improved freeze-thaw stability.
• Paper Manufacturing: Serves as a surface sizing agent and coating binder to improve printability, surface strength, and ink holdout of paper and paperboard.
• Textile Processing: Employed as a warp sizing agent to protect yarns during weaving, providing a hard, abrasion-resistant film that is easily removed in desizing.
• Adhesive Formulation: Acts as a key component in corrugated board adhesives (starch pastes) and other industrial glues, offering strong bonding and controlled viscosity.
• Pharmaceuticals: Functions as a binder and disintegrant in tablet formulations, where its modified properties ensure precise compaction and dissolution rates.
• Construction Materials: Utilized as an additive in gypsum boards and other building materials to improve binding and processing characteristics.

Quality Control

Our Acid Modified Starch is manufactured under strict quality management systems. Each batch is tested against rigorous specifications for parameters such as viscosity, pH, moisture content, and microbiological purity to ensure compliance with food grade (FCC), pharmaceutical, and relevant industrial standards. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and product consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
