GB 28050-2025 National food safety standard - General rules for nutrition labeling of prepackaged foods
1 Scope
This standard specifies the description and declaration of food nutrition information and properties on the nutrition labeling of prepackaged foods.
This standard is applicable to the nutrition labeling of prepackaged foods directly supplied to consumers. For prepackaged foods not directly supplied to consumers and food transportation/storage packaging, if nutrition labeling is provided, it shall comply with this standard.
2 Terms and definitions
2.1 nutrition labeling
description and declaration on the labels of prepackaged foods intended to inform the consumers of the nutritional information and properties of a food, including the nutrition information, nutrition claims, function claims of nutritional components, and other supplementary information
Nutrition labeling constitutes an integral part of prepackaged food labeling.
2.2 nutrition information
standardized table indicating the food's energy, names of nutritional components, their quantities, and percentages of Nutrient Reference Values (NRV)
2.3 energy
caloric value generated through human metabolism from food components such as proteins, fats, and carbohydrates
Energy shall be calculated by the sum of products obtained by multiplying the indicated values of energy-providing components with their respective energy conversion factors
Energy conversion factors (kJ/g) for energy-providing components: 17 for protein, 37 for fat, and 17 for carbohydrates.
When dietary fiber content is indicated, its energy shall be calculated using a conversion factor of 8 kJ/g.
2.4 nutrient
substances in foods with specific physiological functions that are essential for maintaining growth, development, physical activity, reproduction, and normal metabolism, including proteins, fats, carbohydrates, minerals, vitamins, etc.
2.5 nutritional component
nutrients and other food constituents beneficial to physiological functions
Except for the terms and definition below, refer to GB/Z 21922 for the terms and definitions of other nutritional components.
2.5.1 protein
organic compounds containing nitrogen in foods composed of amino acids as fundamental units
Protein content in foods may be determined either by multiplying nitrogen content with protein conversion factors or by summing individual amino acid contents.
2.5.2 fats and fatty acids
fats (also called triglycerides) consisting of fatty acids and glycerol
fatty acids serving as the general term for chain carboxylic acids in organic acids, divided into saturated fatty acids and unsaturated fatty acids
Saturated fatty acids contain all fatty acids without double bonds in the carbon chain.
Unsaturated fatty acids contain all fatty acids with double bonds in the carbon chain, only including the cis structure. Fatty acids with one double bond in the carbon chain are monounsaturated fatty acids, and those with two or more double bonds are polyunsaturated fatty acids.
Trans-fatty acids refer to all fatty acids that are produced during the processing of oils and fats and those that exist naturally, and contain one or more non-conjugated trans double bonds.
2.5.3 carbohydrates
general term for sugars, oligosaccharides and polysaccharides
The content of carbohydrates in every 100 g of or every 100 mL of food can be calculated by subtraction.
Subtraction: Carbohydrates = 100 - Moisture - Ash - Protein - Fat; when the content of dietary fiber is labeled, its content shall also be subtracted. When the contents of protein and fat reach the "0” threshold value, and the sources of carbohydrates are sugars and/or starches, the addition may also be used.
Addition: Carbohydrates = Sugars + Starch.
