ISO 11292 Soluble Dietary Fiber Analysis in Food
The analysis of soluble dietary fiber in food is crucial for ensuring product quality, compliance with nutritional labeling regulations, and meeting consumer health expectations. This service focuses on the ISO 11292 standard, which provides a precise method for quantifying soluble dietary fiber content using a combination of acid hydrolysis followed by enzymatic digestion.
The process begins with selecting an appropriate sample size based on the expected fiber content and the desired level of precision. For instance, a typical sample weight might range from 2 to 5 grams depending on the product type. Samples are then ground into fine powders if necessary using a laboratory mill or grinder.
Hydrolysis is carried out by treating the sample with sulfuric acid at specific temperature and time conditions outlined in ISO 11292. This step aims to remove non-fibrous components such as proteins, lipids, and minerals, leaving behind only the complex carbohydrates that constitute dietary fiber.
Following hydrolysis, the sample undergoes enzymatic digestion using enzymes like alpha-amylase and protease to break down easily degradable polysaccharides. The remaining residue is then filtered and washed thoroughly to remove any residual compounds not associated with true dietary fiber.
The final step involves drying the filtrate and weighing it accurately, which represents the amount of soluble dietary fiber present in the original sample. This value is calculated using a specific formula provided within the ISO standard.
This method ensures accurate quantification of soluble dietary fiber content across various food matrices including cereals, fruits, vegetables, and processed foods. Compliance with this analysis can significantly enhance brand reputation by ensuring products meet regulatory requirements while also providing valuable insights into nutritional composition for product development purposes.

With our comprehensive approach, we help clients stay ahead of industry trends while maintaining rigorous quality control measures.
Scope and Methodology
The scope of the ISO 11292 standard includes the determination of soluble dietary fiber in various types of food products, such as cereals, fruits, vegetables, and processed items. This comprehensive approach ensures that all relevant food categories are covered under this analytical framework.
The methodology employed follows stringent procedures defined by the ISO document itself. It involves several key steps starting from sample selection through to final quantification:
- Sample preparation: Grinding and drying of the sample as needed
- Hydrolysis: Treatment with sulfuric acid at specified conditions
- Enzymatic digestion: Breakdown using alpha-amylase and protease
- Drying and weighing of the residue obtained post-processing steps
The entire process is meticulously documented to ensure traceability and reproducibility. Our laboratory adheres strictly to these procedures, ensuring consistent results regardless of who performs the analysis.
For more detailed information on the exact protocols involved in each step, interested parties are encouraged to consult the full text of ISO 11292:2017 which provides all necessary instructions and recommendations for conducting this type of analysis accurately.
