Read beyond pass or fail.

Based on national food safety standards including GB 2760—2024, with controls tied to the additive and food category.

Authorisation

Confirm that the additive is listed and that use is permitted in the target food category.

Numeric limit

An entry may specify a maximum use level, maximum residue level or another condition; use the exact value and unit in that entry.

Without a fixed value

Where use is allowed as needed for production, the stated scope and the general principles of the standard still apply.

Practical lookup

Additive name/code + food category number + maximum use or residue level

Preservatives, antioxidants, sweeteners, colouring matter and other classes are governed through separate regulations and schedules.

Authorisation

First confirm that the substance is permitted, then check the scheduled food category and conditions of use.

Numeric limit

Some additive–food combinations have a maximum permitted level, interpreted using the schedule’s unit and food basis.

Without a fixed value

Some uses are governed by good manufacturing practice (GMP), limiting use to the amount needed for the intended technical effect.

Practical lookup

Additive class + applicable schedule + food category + maximum permitted level/GMP condition

Uses a positive-list system specifying additive identity, specifications, permitted scope and limits.

Authorisation

Only listed additives may be used in listed food categories; an unlisted substance or use is not permitted.

Numeric limit

Apply the limit and specification for the exact entry and confirm that the food category falls within its scope.

Without a fixed value

Even without one numerical value, use should be kept to the minimum needed for the intended effect and comply with entry conditions.

Practical lookup

Additive Chinese/English name + permitted food scope + limit + specification

Uses an EU positive list; Annex II sets out authorised additives, food categories and conditions of use.

Authorisation

Check the E-number or substance name, food category, restrictions and exceptions in the entry.

Numeric limit

A maximum level may be expressed in mg/kg, mg/L or another unit; unless stated otherwise, it applies to food as marketed.

Without a fixed value

“Quantum satis” sets no fixed numerical maximum, but use is limited by GMP to the minimum needed and must not mislead consumers.

Practical lookup

E-number + Annex II food category + maximum level/quantum satis + footnotes

Rules differ across the Americas; this comparison uses U.S. federal rules as an example. A food additive use must be authorised, or its intended use must have a GRAS basis.

Authorisation

Confirm the substance identity, intended use, food scope, technical effect and food-additive authorisation or GRAS basis.

Numeric limit

A regulation may specify food types, maximum amounts and labelling conditions; verify the exact 21 CFR scope.

Without a fixed value

Under GMP, the quantity must not exceed the amount reasonably required for the intended technical effect.

Practical lookup

Substance/CAS + intended use + 21 CFR provision or GRAS basis + conditions of use
