What it is Filled
Magnesium diglutamate is the magnesium salt of glutamic acid, with two singly charged glutamate anions per magnesium ion.
In scope
- Magnesium-to-glutamate stoichiometry and verified substance identifiers
- Glutamate stereochemistry and distinctions between anhydrous and hydrated forms
- Batch composition, assay basis and relevant impurities
- Physical state, dissolution behaviour and stability under recorded conditions
- Hazard evidence and jurisdiction-specific qualification of a defined material grade
Out of scope
- Finished foods, supplements and medicines containing magnesium diglutamate
- Manufacturing equipment and complete production-process models
- Clinical treatment decisions and individual magnesium dosing
- Glutamic acid and other glutamate salts as independent substances
- Magnesium metabolism and glutamate signalling as biological systems
Why it exists Filled
Enable an agent to recognise magnesium diglutamate, assess the identity and condition of a particular material, and determine whether evidence supports its intended use.
Distinguishing features Filled
- Verify magnesium and glutamate together with a nominal magnesium-to-glutamate molar ratio of 1:2; a magnesium assay alone cannot establish identity.
- Distinguish glutamate from glutamine and glycinate by an analytical method that identifies the organic component.
- Resolve whether the glutamate is L, D, mixed or stereochemically unspecified before treating similarly named records as equivalent.
- Determine water content and hydrate identity before comparing formula masses, assays or magnesium content.
- Distinguish a characterised magnesium diglutamate material from a physical mixture of magnesium ingredients and glutamic acid.
What robots and AI may and may not do Filled
Must not
- Hide added glutamates from buyers where labelling is required.
- Present it as a medicine or magnesium treatment.
- Claim it is harmful or safe beyond what food safety evaluations support.
Only with a human decision
- Using it in foods for infants or people on medical diets.
May
- Explain magnesium diglutamate as a flavour enhancer and magnesium salt of glutamic acid.
- Report its presence in foods from ingredient lists.
Moral aspects Filled
- Consumers rely on honest ingredient labels.
- Unfounded fear of glutamate has stigmatized some cuisines.
Who is affected
- Consumers
- People on medical diets
- Food producers
Owners Filled
Steward
