Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to identify gluten-bearing material, assess its composition and functional state, and determine suitable handling, testing and uses.
Gluten is a heterogeneous cereal-protein material, principally comprising gliadins and glutenins in wheat, that forms a viscoelastic network upon hydration and mixing; food-labelling usage also encompasses related proteins in rye and barley.
It can be Identify a preparation against a stated gluten definition and documented cereal origin.; Select and compare gluten lots for a specified network-forming application using comparable tests.; Hydrate, mix or otherwise condition a sample and assess the resulting functional state.; Choose an analytical method appropriate to intact, processed or hydrolysed material.; Segregate, store and transfer gluten-bearing material under documented cross-contact controls.; Accept, reject or hold a lot against an intended-use specification and the available evidence..
Distinguishing features
Distinguish gluten from starch by recording protein-fraction evidence rather than inferring identity from cereal origin or powder appearance.
Distinguish gluten from whole flour by recording whether it is an isolated protein-rich material or a component within a flour matrix.
Distinguish wheat gluten from individual gliadin or glutenin fractions by documenting the preparation's fraction composition.
Distinguish gluten concentration from gluten functionality: detection of relevant proteins does not establish that a material can form a useful dough network.
Distinguish the wheat-focused functional meaning from broader food-safety meanings by naming the cereal proteins included under the selected definition.

Gluten identity and composition Establishes what gluten means in the record and what the material contains.
