Mono- and Diglycerides of Fatty Acids
1. Technical Overview & Food Applications
E471 is omnipresent in commercial baked goods and dairy fats. Because it is synthesized via glycerolysis of fats, if slaughterhouse tallow is used in the refinery, the finished food product is non-halal.
Primary Food Applications: Bread loaf softness, margarines, ice creams, cake mixes, chocolate fat bloom prevention.
2. Halal Compliance & Critical Non-Conformance Vectors
Hidden Biological & Solvent Risks
Commercial fat splitting of animal tallow (bovine/porcine); unsegregated thermal cracking towers
Approved Halal Alternatives
100% Vegetable Palm-derived E471, Sunflower Lecithin (E322), Polyglycerol Polyricinoleate (E476)
3. Scientific Auditing & Testing Protocol
| Audit Metric | Circle H Food Verification Specification |
|---|---|
| International Standard Verdict | Requires verified 100% plant-origin (palm/soy) feedstock and dedicated esterification vessels |
| Laboratory Testing Protocol | GC-FID Fatty Acid Carbon Chain (C16:C18) Profiling & Isotope Ratio Mass Spectrometry (IRMS) |
| Chain of Custody & Abattoir Audit | 100% verified Islamic slaughter (*Dhabihah*) traceability for ruminant derivatives; complete avoidance of porcine slaughterhouse co-products. |
| Cross-Contamination & Solvent Limits | Strict limit on residual ethanol in finished food (<0.5% or <0.1% per national standards); verified non-alcoholic flavor carriers. |
