Total fiber determination (rapid integrated method)

Dietary fiber plays a major role in human and plant nutrition. It is recognized for its beneficial effects on intestinal transit, glycemic regulation, and satiety. Measuring total fiber content is an essential step in the formulation, quality control, and nutritional labeling of foods and supplements. To meet the growing need for rapid and reliable analysis, the simplified integrated gravimetric method provides accurate results in a short timeframe while complying with international standards.

Integrated and rapid analytical method

The determination of total fiber by gravimetry is based on simplified enzymatic digestion followed by a separation and weighing step. This method has several advantages:

• a significant time saving compared to traditional protocols,
• a reduction in handling steps,
• reliability comparable to reference methods,
• better efficiency for routine quality control.

It is particularly suitable for manufacturers wishing to combine speed and precision in their nutritional analyses. This approach complements other reference methods available at YesWeLab, such as the measurement of insoluble, soluble and total fiber according to AOAC or Codex protocols.

Industrial applications and compliance issues

Rapid determination of total fiber concerns many sectors:

• Food industry : quality control of flours, vegetable powders, processed products and functional foods.
• Nutraceuticals : standardization of fiber-enriched food supplements and validation of “high fiber” claims.
• Plants and nutritional ingredients : characterization of plant extracts used in health and well-being formulations.
• R&D and product innovation : development of new food ranges optimized for fiber intake.

This service is complementary to other essential nutritional analyses, such as protein dosage , total carbohydrate dosage or calorie calculation .

Matrices analyzed for total fibers

The rapid method is applicable to a wide range of matrices: plant powders and flours, functional ingredients, processed foods (biscuits, cereals, nutritional bars), dietary supplements, and innovative fiber-based formulations. Each sample type benefits from a tailored preparation to ensure accurate results.

Importance of speed and reliability

In a context of high regulatory requirements and tight industrial deadlines, the rapid integrated method offers an optimal compromise between scientific reliability and operational efficiency. It allows:

• reduce time to market,
• ensure consistency and reproducibility of batches,
• justify nutritional claims in accordance with INCO Regulation No. 1169/2011,
• strengthen product traceability and transparency.

This service is part of a nutritional enhancement approach, like other regulated analyses such as sodium or total lipid dosage.
