Starch Extraction Service - Creative Biolabs

Starch is a high molecular weight polysaccharide with many glucose molecules connected by glycosidic bonds. It is widely found in cereals (such as corn, wheat, and rice), tubers (such as potatoes and cassava), beans, and other plants. Starch is an important natural resource with various application values in industry, food, and medicine. Creative Biolabs is an expert in the field of Carbohydrates and has professional process knowledge and experience. We use professional equipment to efficiently extract high-quality starch from different raw materials and perform reliable Content Analysis and Physical Property Analysis services on the extracted starch.

We provide clients with one-stop services from raw materials to finished products to meet clients' all-around needs in R&D, production, and quality control. We will use different extraction methods and steps according to different starch sources and client needs. The following are commonly used starch extraction methods:

Wet Extraction

Steps: Wet extraction is the most traditional starch extraction method. First, we soak the raw materials (such as cereals and potatoes) in water to fully absorb water and soften them. Then, we use grinding equipment to grind the soaked raw materials to destroy the cell structure and release starch granules. The milled slurry is screened and centrifuged to remove cellulose, protein, and other non-starch components to obtain starch milk. Finally, we obtain pure starch products through the steps of sedimentation, washing, dehydration, and drying of starch milk.
Features: This method is a widely used starch extraction method with mature technology, and simple operation and is suitable for large-scale industrial production.

Alkaline Extraction

Steps: We mix the raw materials with an alkali solution (such as low-concentration sodium hydroxide solution), which can dissolve protein and part of hemicellulose, destroy the cell wall structure, and release starch granules. Then, starch and dissolved impurities are separated by centrifugation, filtration, and washing.
Features: This method effectively removes protein and improves starch purity.

Acid Extraction

Steps: Acid can hydrolyze non-starch polysaccharides such as hemicellulose and pectin, destroy cell walls, and release starch granules. We place the raw materials under acidic conditions (such as dilute hydrochloric acid, and dilute sulfuric acid) for reaction, and then adjust the pH value of the reaction solution to neutral through neutralization. Then, starch is separated by filtration or centrifugation. Finally, the starch is washed and dried.
Features: This method effectively destroys the cell structure and has a fast reaction speed. However, acid-resistant equipment and materials are required.

Enzymatic Extraction

Steps: We mix the raw materials with biological enzymes (such as cellulase and hemicellulase), which can selectively degrade non-starch polysaccharides in the raw materials, destroy the cell wall structure, and release starch.
Features: This method has mild conditions, high specificity, high product purity, and is environmentally friendly and pollution-free. However, the cost of enzyme preparations is high, the reaction time may be long, and the process control requirements are high.

In addition, we also process the raw materials through mechanical separation, organic solvent extraction, and supercritical fluid extraction to extract high-quality starch. Creative Biolabs can tailor the optimal starch extraction solution according to different raw material characteristics and client needs. Moreover, combined with Starch Quantitative Analysis services, we provide clients with a one-stop comprehensive solution from extraction to analysis. In addition, as a leading expert in the field of glycobiology, we also provide a variety of Monosaccharides, Oligosaccharides, Polysaccharides, and Amino sugar analysis services. Please contact us if you have more questions to inquire, we are very happy to answer you.

Published Data

Starch, as an energy-rich substance, plays a key role in many industries such as medicine, textiles, and polymer materials. This paper aims to explore in depth the various technical approaches to extracting starch from tubers. The following figure shows a process for obtaining starch from tubers:

Wet grinding is a relatively simple way to obtain starch. Although this method can obtain starch with a white color and fewer contaminants, it takes a long time and has relatively low production efficiency. Therefore, in the actual starch extraction process, it should be considered to combine traditional methods with modern mechanical technology to optimize the extraction process and improve production efficiency.
