Critical Points of Isinglass, L-Cysteine, and Flavorings: How to Trace Them

The halal status of a product is not determined by a single ingredient alone. Some ingredients have a clear status, while others depend on their source. Isinglass, L-Cysteine, and flavorings belong to the latter group. All three frequently appear in everyday products, but their origin is not always easy to determine from the label.

This article discusses the critical points of these three ingredients and the steps to trace them. The reference used is the criteria of the halal product assurance system (SJPH) as stipulated in the Decree of the Head of BPJPH Number 57 of 2021, which includes ingredient criteria as one of the five SJPH criteria.

Why "source-dependent" ingredients need attention

In practice, ingredients can come from plants, animals, or microbial processes. The same ingredient can be produced from different sources. Therefore, the ingredient name on the label is not enough to conclude its halal status. What determines it is the origin of the ingredient and the process it undergoes.

Law Number 33 of 2014 on Halal Product Assurance places the determination of halal status as the authority of MUI, while halal certificates are issued by BPJPH. For business actors, the task is to prepare evidence and documentation that clearly explains the origin of ingredients.

Isinglass: a clarifier from fish swim bladders

Isinglass is a fining agent derived from fish swim bladders. This ingredient is commonly used in beer and wine, and in some packaged juices. Its status depends on the source and process.

The critical point is not only the origin of the fish, but also whether the ingredient is used in products whose halal status is indeed in question. For non-alcoholic beverage products, plant-based clarifier alternatives such as bentonite or carrageenan are available. Tracing isinglass means examining purchase documents, ingredient specifications, and supplier information about origin and process.

L-Cysteine (E920): bread dough softener

L-Cysteine is a dough softener that has historically been extracted from human hair or poultry feathers. This ingredient is commonly used in mass-produced white bread, burger buns, and commercial pizza dough.

The critical point lies in the extraction source. Available alternatives are microbially fermented (non-animal) L-Cysteine that has been certified, or plant-based dough softening enzymes. Tracing it requires business actors to request written information from suppliers about the production method, not just the trade name of the ingredient.

Flavorings: solvents and bases that need to be examined

Flavorings are added tastes whose solvents are often alcohol, and whose bases may be animal-derived. This ingredient appears in soft drinks, snacks, candies, flavored dairy products, and instant noodles.

There are two things that need to be traced. First, the solvent used. Second, the flavoring base itself. Available alternatives are halal-certified flavorings with plant-based solvents (not ethanol) and plant-based or microbial bases. Because flavorings are often mixtures, composition documents from suppliers are key.

Stearic acid and magnesium stearate: another example

In addition to the three ingredients above, stearic acid and magnesium stearate (E470, E572) are also ingredients whose status depends on the source. Both are used as anti-caking agents in tablets and powders, and can come from palm oil or animal fat. Products that often use them are medicinal tablets and supplements, instant drink powders, and pressed powder cosmetics. The alternative is a halal-certified plant-based version, generally from palm oil.

Steps to trace ingredients

Tracing does not have to be complicated, but it needs to be consistent. The following steps can serve as a guide:

1. Map the ingredients. List all ingredients used, including additives in small amounts.
2. Request documents on ingredient origin. Ingredient halal certificates, supplier information, or production specifications stating the source and process.
3. Check name consistency. Ensure the ingredient name in the documents matches that stated on the label and formula.
4. Record critical points. Mark ingredients whose status depends on the source and explain the alternatives.
5. Keep the evidence. These documents become part of fulfilling the ingredient criteria in SJPH.

The ingredient criteria in Kepka BPJPH 57/2021 do not stand alone. These criteria are related to commitment and responsibility, halal product process, product, as well as monitoring and evaluation. This means that ingredient tracing needs to become a habit, not a one-time activity.

The role of documents in certification readiness

Many issues with ingredient critical points arise not because the ingredient is haram, but because its origin is not documented. Business actors who have purchase records, ingredient specifications, and supplier information are better prepared when asked to explain the origin of ingredients.

For ingredients whose status depends on the source, clarity of documents is a form of precaution. The determination of halal status remains the authority of the MUI Fatwa Commission or the Halal Product Fatwa Committee, and certificates are only issued by BPJPH. Therefore, the task of business actors is to provide honest and complete information.
