Hemicellulose Production Service

Leading the Way in Sustainable Hemicellulose Production Solutions

Hemicellulose, a type of polysaccharide primarily found in the cell walls of plants, is an essential component alongside cellulose and lignin. Its unique structure and properties make it valuable in various industries such as papermaking, food production, medicine, and more, contributing to its significant economic importance. CD BioGlyco has been providing professional Marine Plant Polysaccharide Production Services to clients for many years, including but not limited to the production of Agar, Porphyran, Fucan, Cellulose, and hemicellulose. The details of our hemicellulose production service are as follows.

Organic Solvent Extraction

Our experts perform chemical extraction of hemicellulose by using different solvent systems. For example, we perform sequential extraction by using neutral dioxane acidic dioxane, dimethyl sulfoxide (DMSO), and KOH under heat. The composition of the extracted hemicellulose depends on the solvent used. In neutral dioxane, more branched structures containing albino xylan and β-glucan type polymers are obtained. Whereas, in acidic dioxane, DMSO, and KOH solutions, structures are obtained consisting of (1→4)-β-D-xyloside residue backbone and low substitution of L-arabinofuranoside and 4-O-methyl-α-D-glucuronic acid chains as side chains.

Physical-chemical extraction

We chop the raw material containing hemicellulose into appropriately sized pellets and pre-treat them to remove the impurities. Subsequently, we mix the pretreated biomass pellets with a solvent (e.g. an alkaline solution) and then subject them to ultrasonic treatment or microwave treatment. The high-frequency vibrations generated by ultrasound produce an acoustic cavitation effect between the solute and the solvent, resulting in the sudden rupture of tiny bubbles in the solution, which disrupts the cell wall structure and separates the components. Microwave radiation rapidly heats the sample, creating a thermal effect within it that promotes the extraction of hemicellulose. After ultrasonic treatment or microwave treatment, the solution is separated and collected to obtain an extract containing hemicellulose for subsequent purification and characterization.

Applications

Due to its properties of high molecular weight, biodegradability, and environmental friendliness, hemicellulose is widely used in the manufacture of packaging materials.

Hemicellulose can be used in the preparation of drug retardants and drug coating materials to improve drug stability and control release rates.

Hemicellulose can be used to prepare biomedical materials such as artificial blood vessels and tissue-engineered scaffolds.

Advantages

Our extraction method does not convert acetyl groups in cellulose cell walls to acetic acid, so the structure of hemicellulose can be well maintained.

Our extracted hemicellulose, with its high purity, opens up a wide range of possibilities for further utilization in various industries.

By adjusting the composition of the organic solvent system, we help you obtain hemicelluloses with different branching degrees and thermal stability.

Frequently Asked Questions

What is hemicellulose?

Hemicellulose is a type of polysaccharide found in the cell walls of plants, alongside cellulose and lignin. It differs from cellulose in structure and composition, often being more branched and containing a variety of different sugars such as xylose, glucose, mannose, and galactose. Hemicellulose plays a structural role in plant cell walls, contributing to their strength and flexibility.

What is the difference between hemicellulose and other cellulose?

Hemicellulose is distinctly different from other cellulosic substances such as cellulose and lignin. Cellulose is a straight-chain structure composed of β-glucan units that provide strength and stability to plant cell walls, while lignin is a complex non-saccharide polymer that enhances the water and rot resistance of cell walls. In contrast, hemicellulose consists of a variety of sugar units, usually branched-chain structures that act as fillers and supports, while being more readily broken down into simple sugars in biodegradation, and having a more diverse chemical composition and function.
