Accurate determination of the nutritional composition of food products is one of the most important indicators of quality in modern food production. As consumers become increasingly aware of product labels and regulatory requirements continue to evolve, Nutritional Analysis has become more than a technical quality control procedure—it is now a fundamental component of reliable food production.
Accurate determination of protein, fat, carbohydrate, and energy values helps ensure compliance with regulatory requirements while providing consumers with transparent and reliable information. For this reason, Nutritional Value Analysis is considered an integral part of quality management systems.
Performed under laboratory conditions, Nutritional Analysis reveals the actual composition of food products and provides scientific data to support nutrition labelling. This enables nutrition declarations to be based on measurable analytical results rather than theoretical calculations.
Nutritional Analysis is the process of determining the macro- and micronutrient composition of a food product using internationally recognized analytical methods. These analyses establish the nutritional profile of the product and enable its energy value to be calculated.
The main objectives are to:
Nutritional analysis should be regarded not only as a regulatory requirement but also as a scientific verification process.
Incorrect nutritional declarations may result in significant consequences, ranging from administrative sanctions to product recalls. In addition, accurate analytical results contribute to maintaining control over production processes.
For food products bearing nutrition declarations, the declared values are expected to be verifiable. Information that is not supported by analytical results may result in non-compliance during regulatory inspections.
Transparent and accurate nutritional information is one of the key factors that enhances consumer confidence in food products.
Variations in raw material quality or production processes may affect the nutritional profile of a product. Regular analysis enables these changes to be monitored and controlled.
Analytical data provides objective verification for product reformulation objectives, such as reducing fat or sugar content or increasing protein levels.
The nutritional profile of a food product may include different analytical parameters depending on the product matrix and formulation.
The primary components included in most nutrition declarations are:
Depending on the product category, the following parameters may also be evaluated:
For fortified foods and products carrying nutrition claims, the determination of vitamin and mineral content is particularly important.
Not every food product requires the same analytical scope. The appropriate approach is to determine the analytical parameters according to the characteristics of the product.
At Bilim Laboratories, we provide accredited Nutritional Analysis services in accordance with the Turkish Food Codex Regulation on Food Labelling and Consumer Information.
Energy Value Determination refers to the scientific calculation of the caloric value of a food product. The energy value is generally determined by analysing the amounts of protein, fat, and carbohydrates, followed by the application of internationally accepted calculation factors, such as the Atwater and FAO conversion factors.
This approach provides a far more reliable nutritional declaration than theoretical estimations.
The key considerations in energy value calculation include:
An accurately calculated energy value is one of the most important components of a nutrition declaration.
The nutritional composition of food products is not constant and may be influenced by various factors.
For agricultural products, factors such as climate, soil conditions, and harvest time may affect the nutritional composition.
Heat treatment, drying, fermentation, and storage conditions may result in changes to nutritional values.
Changes made to a product formulation may directly affect its energy value.
For this reason, nutritional analyses should not only be performed during product development but also repeated when necessary to ensure that nutritional information remains accurate and up to date.
Although nutritional analysis is important for all food products, it is particularly critical for the following product groups:
For these products, the nutritional profile is one of the key factors influencing consumer purchasing decisions.
Nutrition declarations provide consumers with some of the most important technical information about a food product. The accuracy of this information is essential not only for regulatory compliance but also as a matter of scientific responsibility.
Analytically verified nutritional values help to:
From this perspective, nutritional analysis is not merely a testing procedure but a fundamental component of reliable food production.
Accurate determination of the nutritional composition of food products is essential both for regulatory compliance and for providing consumers with reliable information.
While Nutritional Analysis establishes the actual nutritional profile of a product, Nutritional Value Determination and Energy Value Determination ensure that this information is translated into an accurate nutrition declaration.
Nutrition declarations supported by scientific laboratory analyses enhance product transparency and contribute to the sustainability of quality management practices.
