Background

Starch is the main carbohydrate in many It is a polymerized carbohydrate composed of multiple glucose units interconnected by α-1,4-glycosidic bonds and α-1,6-glycosidic bonds. Starch molecules (called starch granules) are usually deposited in plants as discrete semi-crystalline aggregates, the most important energy reserve in plants.

Starch plays a very important role in plant growth and development. In addition, it is also used as food for humans and animals, industrial raw materials, and expanded to many fields such as packaging and drug delivery. For example, starch can be used as a thickener and binder, and can also be used to produce various bioplastics. Its unique microstructure and characteristics provide an excellent model for scientific research. Research on starch can help us explore the relationship between polymer processing and performance, thereby increasing the knowledge of polymer science, especially natural polymers. Highly selective purification and comprehensive analysis of starch are crucial for research. Although there is no single all-around method, a variety of techniques for analyzing complex carbohydrates have been developed.

Key Technologies

• Advanced Chromatography

We utilize high-performance chromatography techniques, such as gel-permeation chromatography (GPC), to analyze the molecular weight distribution of starch and its branches. This is a critical step for determining the amylopectin chain length distribution, which significantly impacts properties like gelatinization.

• Thermal Analysis

Our state-of-the-art thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) systems precisely measure the thermal stability and degradation profile of starch under various conditions. This provides crucial data on how your starch will perform during thermal processing.

• Precision Granule Sizing

We combine the speed of laser diffraction sizing (LDS) with the unparalleled detail of digital image analysis (IA). This dual-platform approach allows us to accurately identify and quantify the different populations of starch granules (A, B, and C-type) and measure critical shape factors, providing a more robust profile than a single method could achieve.

• Protein and Enzyme Purification

For the highest level of purity, our services include advanced purification protocols. We utilize modern chromatography resins and techniques to ensure the removal of contaminants, such as proteins and enzymes, that can interfere with accurate starch analysis and affect product performance.
