e-label - Editor - Product Information - Nutritional Table - e-label Energy Calculator Logic

The e-Label solution offers a convenient and dynamic way to display nutritional information to consumers, including energy content. The Nutritional Table Energy Calculator embedded within the e-Label platform applies established formulas and regulatory guidelines, such as those specified by the EU Regulation No. 1169/2011, to derive energy content in kilojoules (kJ) and kilocalories (kcal) and automates the calculation of energy values, ensuring accuracy and consistency across all product labels:

It simplifies the labeling process by automatically calculating energy values based on the macronutrient composition of a product or standardized averages for specific product categories.

The Energy Calculator Logic is based on standardized formulas used in nutritional science to calculate the energy content (usually in kilojoules (kJ) and kilocalories (kcal)) of a product. The calculation is derived from the macronutrient content — fats, carbohydrates, and proteins — present in the product.

The energy calculator, for the time being, is a pure calculator. 

Important to note: 

• The values for organic acid and polyols are pre-populated with default values but can be changed.
• Data entered here will be erased once you leave the editor page.
• None of the values you entered/ edited are stored in the calculator itself - once you leave the editor page, everything will go back to the default.
• Once you click "CALCULATE" the result is transferred to the table and saved there.

Adjustment for Averaging 

The USE AVERAGE ENGERY VALUE button will only show up if you have already selected a the product type earlier in the editor: 

When using the "Use Average Energy Values" feature, the tool selects standardized averages from the regulatory table based on parameters like alcohol percentage, and sugar content. Slight variations may occur due to rounding practices or updates to the regulatory guidelines: 

Addressing Variations in Values

One common question arises when calculated values slightly differ from those in regulatory tables. For example:

• A still wine with a sugar content labeled as “SEC” (dry) and an alcohol content between 12.1–15% may show 330 kJ (79 kcal) per 100 ml in the e-label calculator, compared to 328 kJ (79 kcal) in the DGCCRF table.

This discrepancy occurs because the e-label tool incorporates rounding rules and dynamic inputs to provide flexibility for label customization. Regulatory authorities typically accept these small deviations as long as they are reasonable and documented.
