ISO 20810:2026 - Whole grain — Definition and technical criteria
ISO 20810:2026 - Céréales complètes — Définition et critères techniques
ISO 20810:2026 is an International Standard from ISO that defines whole grain as a food ingredient and sets technical criteria for whole-grain foods and foods containing whole grains. It is written for the food and beverage industry, food trade, and food labelling and claims, including business-to-business and business-to-consumer communication. The document gives a common basis for describing whole grain on packaging and in claims after harvest and collecting of the grain.
What does ISO 20810:2026 specify?
ISO 20810:2026 specifies the definition of whole grain as a food ingredient and the technical criteria for calling a food whole-grain or for making whole-grain claims. It also sets the document’s coverage, which is broad across food and beverage companies and applies in trade, supply chains, packaging, labelling and claims.
The scope is limited to post-harvest/collecting of the grain. In practice, that means the standard is about how grain is handled, identified and presented as an ingredient or food characteristic, not about crop production.
| Annex | What it covers |
|---|---|
| Annex A | Calculation of the percentage of whole-grain ingredients based on dry mass |
What are the key requirements of ISO 20810:2026?
ISO 20810:2026 separates two questions: when a grain ingredient can be called whole grain, and when a finished food may be described or claimed as whole-grain. The practical effect is that companies need to track ingredients, process losses and moisture basis, then use those figures consistently in labelling and claims.
Whole grain as an ingredient
Clause 4 applies the whole-grain definition to cereal grains in the Poaceae family and to the pseudocereals amaranth, buckwheat, tartary buckwheat and quinoa. For processed material to count as whole grain, the edible anatomical parts must remain in the same relative proportions as in the intact kernel or seed.
Clause 4 also allows grain to be processed by dry or wet methods if good manufacturing principles are followed and nutrient value is not diminished. In practice, this means the process must preserve the grain’s whole structure as far as reasonably possible.
Processing allowances
Clause 4 allows temporary separation into fractions if the fractions are recombined in the original proportions. It also allows fractions from different batches if they are combined to recreate the original proportions. This matters for milling, blending and ingredient standardization.
Clause 4 permits small unavoidable component losses linked to safety and quality, and accepts minimal removal of outer layers. The allowed removal must be evidence-based and kept to a minimum, so producers need documented control of processing losses.
Clause 4 adds a specific point for malted or sprouted grains: the sprout length should not exceed kernel length. For users, this is a clear control point when marketing sprouted grain ingredients.
Labelling and claims
Clause 5 says prepackaged food must not be presented in a false, misleading or deceptive way. For content claims such as “source of whole grain” or “made with whole grain,” the food must contain at least 25 % whole-grain ingredients on a dry-mass basis.
Clause 5 sets a higher threshold for naming a product with whole grain, such as “Whole grain wheat bread”: the food must contain at least 50 % whole-grain ingredients on a dry-mass basis. That distinction matters because product names carry a stronger impression than a general claim.
Clause 5 also points readers to dry mass as the calculation basis for front-of-pack labelling. Annex A then shows how to calculate that percentage from ingredient mass and dry-matter content.
What terms does ISO 20810:2026 define?
- Cereal - a grain from plants in the Poaceae family; the note links it to ISO 5526 for plant lists.
- Pseudocereal - a grain from a plant outside Poaceae that has similar nutrient composition and food use to cereals.
- Claim - any representation that states or suggests a food has a particular quality, such as origin, composition or nature.
- Food - a substance intended for human consumption, including drink and chewing gum.
- Ingredient - a substance used to make a food and present in the final product, even if modified.
- Sprouted grain - grain in which the radicle or plumule is visible to the naked eye.
- Whole grain - a kernel or processed kernel in which endosperm, germ and bran remain in the same relative proportions as in the intact grain.
- Whole-grain food - a food containing at least a specified proportion of whole-grain ingredients.
Who uses ISO 20810:2026?
ISO 20810:2026 is used by food and beverage manufacturers, ingredient suppliers, traders, retailers and labelling teams. Quality managers and regulatory staff use it to decide how to classify ingredients, set internal specifications and support packaging or claims wording. It is also relevant in global supply chains where buyers and sellers need the same technical basis for whole grain.
Which standards are used with ISO 20810:2026?
| Reference | What it contributes |
|---|---|
| ISO 712 (all parts) | Moisture content determination, which supports dry-mass calculations in Annex A |
| ISO 5526 | Nomenclature for cereals, pulses and other food grains; cited in the note to the term cereal |
| ISO 5527:2015 | Vocabulary for cereals; cited as the source for cereal and sprouted grain definitions |
| CXS 1-1985 | General Standard for the Labelling of Prepackaged Foods; source for terms such as claim, food, ingredient, label and labelling |
| CXG 1-1979 | General Guidelines on Claims; cited with the labelling and claims rule in Clause 5 |
| Codex Alimentarius Commission Procedural Manual | Source for the definition of food used in Clause 3 |
What does the ISO 20810:2026 document contain?
ISO 20810:2026 contains a scope, terms and definitions, technical criteria for whole grain as an ingredient, and technical criteria for labelling and claims. It also includes Annex A, which gives a generic dry-mass calculation method and a worked bread example. The bibliography points to supporting sources for terminology, moisture determination and labelling concepts.

Introduction
The purpose of this document is to provide the definition and technical criteria for whole grain as a food
ingredient (or “raw material”) for use by the food and beverage industry at a global level, as well as technical
criteria for food labelling and claims for whole-grain foods and foods containing whole grains.
In drafting these technical criteria, the Technical Committee has taken into account the consensus definitions
[1]
of whole grain as a food ingredient, and that of whole-grain foods developed by the Whole Grain Initiative
Working Group of the International Association for Cereal Science and Technology (ICC), and ratified by
the Cereals & Grains Association (formerly American Association of Cereal Chemists International), ICC
and the European-based Health Grain Forum. In addition to the technical criteria itself, the publication
and its supplementary materials provide referenced background information, with explanations, and
recommendations for matters to be determined at national level.
It is noted that current definitions for whole grain as food ingredient only refer to cereal grains and certain
pseudocereals and are similar around the globe, whereas definitions of whole-grain foods show major
differences. Both the existence of two types of definitions and the major differences in whole-grain food
definitions are causing confusion. This document therefore includes one whole-grain definition: for whole
grain as food ingredient. For whole-grain foods technical criteria for food labelling and claims are provided,
derived from the definition in Reference [1].
Conformity to this document helps to ensure a level playing field and fair practices in business-to-business
relationships, international trade, and food labelling and claims.
NOTE Legally required information, food labelling or claims, or other applicable legal requirements can apply.

Introduction
L’objectif du présent document est de fournir la définition et les critères techniques pour les céréales
complètes en tant qu’ingrédient alimentaire (ou “matière première ”) à l’usage de l’industrie agroalimentaire
au niveau mondial, ainsi que les critères techniques pour l’étiquetage des denrées alimentaires et les
allégations pour les aliments à base de céréales complètes et les aliments contenant des céréales complètes.
Lors de la rédaction de ces critères techniques, le Comité technique a pris en compte les définitions
consensuelles des céréales complètes en tant qu’ingrédient alimentaire, et celles des aliments à base
[1]
de céréales complètes élaborées par le Groupe de travail de l’Initiative sur les céréales complètes de
l’International Association for Cereal Science and Technology (ICC), et ratifiées par la Cereals & Grains
Association (anciennement American Association of Cereal Chemists International), l’ICC et le Forum
européen HealthGrain. En plus des critères techniques eux-mêmes, la publication et ses documents
complémentaires fournissent des informations de base référencées, avec des explications et des
recommandations sur des questions à déterminer au niveau national.
Il est à noter que les définitions actuelles des céréales complètes en tant qu’ingrédient alimentaire ne se
réfèrent qu’aux grains de céréales et à certaines pseudocéréales et sont similaires dans le monde entier,
tandis que les définitions des aliments à base de céréales complètes présentent des différences majeures.
L’existence de deux types de définitions et les principales différences dans les définitions des aliments à base
de céréales complètes sont une source de confusion. Le présent document comprend donc une définition
unique des céréales complètes: celle relative aux céréales complètes en tant qu’ingrédient alimentaire. Pour
les aliments à base de céréales complètes, des critères techniques dérivés de la définition de la référence [1]
sont fournis pour l’étiquetage des denrées alimentaires et les allégations.
La conformité au présent document contribue à assurer des conditions de concurrence équitables et des
pratiques équitables dans les relations entre entreprises, le commerce international, l’étiquetage des denrées
alimentaires et les allégations.
NOTE Des informations légalement requises, l’étiquetage des denrées alimentaires ou les allégations, ou d’autres
exigences légales applicables peuvent s’appliquer.
