Quick answer
Break components down until each source can be judged independently. Expand compound ingredients level by level from their ingredient lists, including processing aids, flavor carriers, solvents and enzyme media. For confidential items, a branded grade plus a supplier declaration or third-party halal certificate replaces percentages. A Chengdu maker found animal-derived glycerin only at level three; the LHLN marks each material's source type and missing evidence.
Detailed explanation
Depth rule
Keep breaking until you reach single substances such as water, salt or soybean oil, or a final commercial grade that can be verified. Whenever a component is still named as compound seasoning, shortening or non-dairy creamer, expand it one more level; there is no fixed number of tiers.
Hidden components that must be opened
- Flavors: solvents, carriers and antioxidants.
- Enzyme preparations: enzyme type and culture-medium source.
- Colors and gums: carriers, diluents and encapsulating materials.
- Processing aids: release oil, antifoam and filter media.
How to present the breakdown
- Use an indented hierarchy table with linked parent and child numbers and continuous page numbering.
- State supplier, usage level and halal-certificate number on each line.
- For confidential components, use a stamped supplier declaration confirming no animal-derived or intoxicating materials. Auditors check whether the entire source chain closes; compound ingredients that cannot be opened are a leading cause of file return, so one extra level of breakdown is the safer choice.
