Status: ✅ working case (anonymized). Client is a Chinese sausage producer using angkak as a colorant. This page started life as a food-science primer; it now lives under case studies because a live file exercises every rule the ingredient touches.

1. Why this file is a useful case
Angkak is one of the few materials where the fermentation route, the colorant chemistry, and the alcohol rule all collide — and now it sits inside an animal product. Two audit traps arrive together:
- Material level: the colorant must satisfy the evidence decision tree like any fermentation-route additive — but most Chinese sausage suppliers have never been asked for halal evidence on their color.
- Product level: the colorant adds nothing animal, but it is an input on a line where cross-contact and additive questions are already live (criterion 3), and its safety profile (citrinin) is now a CoA question in its own right.
The sausage itself (meat, casings, seasonings, other additives) is the main event of the file; the angkak row is where the evidence discipline gets tested in miniature.
2. The ingredient, in one page
Angkak (red yeast rice, red koji, Monascus red) is rice fermented by a Monascus mold; the red color comes from polyketide pigments (monascorubrin, rubropunctatin). It is sold in two forms, and the form changes the questions:
| Form | 中文 | Halal questions that follow |
|---|---|---|
| Whole/ground red rice | 红曲米 / 红曲粉 | media (plant-only?), no animal inputs, cross-contact |
| Extracted colorant | 红曲红 (Monascus red) | everything above plus extraction solvent — often ethanol (source question) or water |
Step classification: fermentation = class D (biological transformation) in the unit-operations taxonomy. Under this body’s operational rule, fermentation-route colors need a halal certificate; where none can be obtained, a flowchart + animal-free statement may suffice per own practice — credible for angkak only if the four conditions hold:
- Substrate is plant-only — rice, and in modern production also soybean/other plant nutrients (not animal peptone or meat extracts); the actual media list must be declared. The old “rice only” shorthand is wrong for large producers — see §4.
- No animal inputs anywhere — nutrients, enzymes, carriers.
- Extraction solvent disclosed — ethanol-extracted 红曲红 raises the alcohol source question; aqueous extraction avoids it.
- No shared equipment with non-halal or alcoholic lines (criterion 3).
If media/process cannot be evidenced, escalate along the decision tree (certificate or replacement) like any other fermentation product.
3. The client file — working checklist
What this file must close, mapped to the criteria:
| Question | Why | Criterion / tool |
|---|---|---|
| Which sausage products carry the color, and as what (红曲红 powder/liquid, or 红曲米)? | defines the material rows and the product list | C4 product list |
| Who actually manufactures the colorant (not the trader)? USCC 统一社会信用代码, SC license scope, name/address | every CoA/letter must name the true maker | C2; China layer |
| Evidence route: halal cert (issuer on the live LHLN list) or flowchart + animal-free statement from the manufacturer | decision tree L2/L3 | C2; template 07 |
| Media list + solvent declaration with ethanol source (khamr or not) | conditions 1 & 3 above | C2 alcohol rule |
| Does the supplier or its site also make 红曲酒 / sell 红糟 lees, or run those on shared lines? | beverage-route derivatives → source rule (§5) | C2/C3 |
| Same-supplier product families: TG酶 (transglutaminase), compound colorants (monascus red blended with sorghum red 高粱红 or β-carotene) | what is delivered must match the register; blends change the material identity | C2 register (IA item 11) |
| Per-batch CoA incl. citrinin; any published non-compliance on the batches in scope | C2 safety item; supplier QMS | C2 item 9 |
| Register row + any brand/supplier switch = pre-approval | Chinese vendors switch often | C5; template 05 |
That checklist is the file in miniature. The next section shows what one real producer looks like when the questions above are asked of it.
4. Supplier intel — Guangdong Kelong (广东科隆生物科技有限公司) 🔎
Tip initially raised in an AI chat session, then verified 2026-09 against the manufacturer’s own site and an official government notice (both cited below).
Company (source: own website): Guangdong Kelong Biotechnology Co., Ltd., established 1995, Jiangmen City, Guangdong (Xinhui District). Describes itself as specialized in research, manufacture and commercialization of food colorants and additives; produces Monascus red by submerged fermentation using rice and soybean with “unique extraction and refining” technology; claims to be one of China’s large-scale monascus and TG-enzyme production bases. Product families include MonascusColor (红曲红 / 红曲黄), TG酶 (transglutaminase), MeatProductsColor and BakingColor; exports to Japan, Korea, Southeast Asia, Europe and the Americas.
2024 finding (official): per the Xinhui District Market Supervision sampling notice 2024 No. 25 (2024-12-26), a batch of 红曲红 produced by Guangdong Kelong failed inspection with citrinin (桔青霉素) above the national food-safety standard. The notice is a production-sector food-additive sampling round; the batch was confirmed non-compliant by an initial lab and a re-inspection lab.
Reading for the halal file:
- Fermentation raw materials are stated as rice + soybean — plant-only, so an animal-free claim remains scientifically credible, but the flowchart/statement must come from the actual manufacturer and name the real media. Do not copy “rice only” from this page into the file.
- Citrinin is safety, not halal status. A mycotoxin exceedance does not make the material haram, and halal certification ≠ food-safety compliance. What it does is trigger criterion 2 item 9 (materials meet safety/health aspects per applicable regulations): request current-batch CoAs showing citrinin, and if a supplier has a published non-conformity, ask for corrective-action evidence before approving them on the register.
- Chinese product-standard context: 红曲红 is a permitted colorant under GB 2760 (permission ≠ halal), and the product standard GB 1886.181-2016 (食品添加剂 红曲红) is the compliance yardstick the CoA cites. Legal-use checks and halal evidence run on separate rails — keep them separate in the report.
5. The alcohol side — the trap is the derivatives
Angkak itself (dried red rice) holds negligible alcohol. The risk sits in what the producer also makes or sells:
| Product | Route | Halal reading (strict operational rule) |
|---|---|---|
| 红曲酒 (red rice wine) | alcoholic beverage from fermented red rice | beverage-alcohol product → khamr-adjacent; not usable on certified lines |
| 红糟 / red vinasse / red lees (wet mash from 红曲酒 brewing, used in cooking) | by-product of alcoholic-beverage brewing | beverage-alcohol derivative → haram at any level under the source rule 🔎 |
| Dishes/marinades made with 红糟 | carries the 红糟 issue into the finished product | treat strictly; finished-product % is not the question — the source is |
Auditor habit: when a sausage recipe or marinade lists 红糟, 红曲酒 or “red wine lees”, ask where the mash came from. If it is lees of red-rice wine brewing, the source rule rejects it regardless of residual percentage; a claimed culinary-only fermentation (not from beverage brewing) must be evidenced and is 🔎 per your LPH’s fatwa basis (the transformation/istihalah question in fermentation primer §4 applies).
6. Audit takeaway
- Which form — 红曲米 or extracted 红曲红 — and who actually makes it?
- Extraction solvent and its ethanol source; plant-only media list in writing.
- Same facility/line making 红曲酒 or selling 红糟 lees?
- CoA per batch incl. citrinin; no published non-conformities on the batches in scope.
- Evidence per the decision tree: certificate (recognized body, live-list check) or flowchart + animal-free statement from the manufacturer (template 07), batch-scoped.
One-line summary: angkak the colorant is credible animal-free territory once media and solvent are disclosed and the manufacturer is the one making the statement; 红糟/红曲酒 the wine-route derivatives are where the halal case falls apart — and citrinin makes the CoA a safety check the register must not skip.
