Carbohydrate Dosage

Carbohydrate analysis allows for the quantification of simple sugars (glucose, fructose, sucrose) and complex sugars (maltose, lactose, polysaccharides) in various food, plant-based, or nutraceutical matrices.
This analysis is essential for nutritional control , verifying product claims (e.g., "no added sugars," "low carbohydrate content"), and characterizing plant extracts .

Analytical methods: HPLC, spectrophotometry and Luff-School

Carbohydrate analysis relies on robust and standardized techniques:

• HPLC-RID (refractive index detector liquid chromatography) : reference method for the separation and individual quantification of sugars (glucose, fructose, maltose, sucrose, etc.).
• Spectrophotometry : colorimetric measurement of total carbohydrate content, often used for raw or complex products.
• Luff-Schoorl method : traditional chemical titration used for the determination of total reducing sugar in food matrices.

These approaches make it possible to meet quality control requirements and ISO , AOAC or CEN .

Applications and areas concerned

Carbohydrate analysis is applicable to many industrial sectors:

• Agri-food : formulation and control of processed products, juices, drinks, confectionery or low-fat products.
• Nutraceuticals : evaluation of the carbohydrate profile in nutritional supplements, powders or plant-based syrups.
• Animal nutrition : determination of assimilable sugars in feed for livestock or pets.
• Plants and plant extracts : biochemical characterization of extracted polysaccharides or natural sugars.

This analysis can be combined with dietary fiber or starch measurements for a complete assessment of the carbohydrate profile .

Analyzed matrices

YesWeLab's partner laboratories perform carbohydrate analysis on:

• Juices, nectars and fermented drinks
• Plant extracts and syrups
• Powders, dietetic foods and nutritional supplements
• Agricultural raw materials and processed products

Each method is adapted according to the matrix , the expected content and the type of carbohydrates to be quantified (reducers, totals, individuals).
