Fiber is a polysaccharide composed of a variety of polymers, which is often applied in the food industry because of its unique functional properties, safety, and green features. Common dietary fiber polysaccharides include cellulose, hemicellulose, and pectin, which are composed of different monosaccharide units. Specifically, cellulose is composed of glucose units, hemicellulose is composed of monosaccharide units such as glucose, xylose, and mannose, while pectin is composed of monosaccharide units such as galactose, galactomannose, and galacturonic acid. These fiber polysaccharides are the main components of most plant cell walls, and they play a vital role in food, especially in human digestion and health. Therefore, providing fiber analysis services can obtain the type, content, and structure information of fiber polysaccharides in samples, providing important data references for food quality assessment, nutritional value research, etc.
Creative Biolabs has a mature Carbohydrate Analysis Platform, and we provide a variety of Polysaccharide Analysis services, including Heparan Sulfate, 3-O-Sulfation Analysis, and fiber analysis services.
Technology: Standard gravimetric method and spectroscopic methods

Results: The authors isolated and prepared cell wall materials (CWM) from cocoa shells through multiple steps, and then compared two determination methods for the determination of dietary fiber in cocoa shells, one was a standard gravimetric method and the other was using chemical methods to acid hydrolyze the polysaccharides separated during the preparation of CWM, and then used spectroscopic methods to analyze the fiber content. The results showed that total fiber levels determined by acid hydrolysis were in good agreement with published standard values, while dietary fiber levels measured by the gravimetric analysis were higher than the standard values, possibly due to the inability of the gravimetric method to distinguish the complex from lignin, resulting in high dietary fiber values.
