Are Enzymes Halal?

The short answer

"Enzymes" is a group of ingredients, not a single ingredient, so there is no one ruling. Enzymes from microbes and plants are halal. Enzymes from animals are halal only if the animal was slaughtered the Islamic way, and they are haram if they come from pigs. The practical problem is that labels rarely name the source.

Which enzymes are halal?

Everyone agrees that these enzymes are halal:

• Microbial enzymes. These are made by fermenting bacteria, molds or yeast. They make up most modern food enzymes.
• Plant enzymes. Examples include bromelain from pineapple and papain from papaya.

Microbial and plant enzymes are now the most common, because they are cheaper and more reliable to make. That is why most enzymes you will meet in food are halal.

Which enzymes depend on the animal?

Some enzymes are taken from animal tissue. These follow the ruling of the animal they came from:

• Rennet, also called chymosin, from a calf's stomach;
• Pepsin, from the stomach;
• Lipase, from glands in the throat or from the pancreas.

These are halal only if they come from an animal slaughtered the Islamic way. Any enzyme from a pig is haram. Our rennet, pepsin and lipase pages explain each one in more detail.

Why is unnamed "enzymes" doubtful?

A label that just says "enzymes" does not tell you where they came from. In foods where an animal enzyme is possible, such as cheese, some breads and meat tenderizers, the cautious ruling is to treat unnamed enzymes as doubtful. Where the enzyme is clearly used for baking or fermentation, it is much more likely to come from microbes.

Common questions

Are enzymes halal or haram?

It depends on the source. Microbial and plant enzymes are halal. Animal enzymes are halal only from an animal slaughtered the Islamic way, and enzymes from pigs are haram. Unnamed enzymes are doubtful when an animal source is possible.

Are microbial enzymes halal?

Yes. Enzymes made by fermenting bacteria, molds or yeast are halal, and everyone agrees on this. They make up most modern food enzymes.

Which foods have animal enzymes?

Cheese is the most common, because it can be made with rennet or lipase from animals. Some meat tenderizers can also contain animal enzymes, although many are made from plants.

How do I know if an enzyme is halal?

Look for "microbial enzyme," a vegetarian symbol or a halal symbol. If a label just says "enzymes" in a food where an animal source is possible, treat it as doubtful.

The bottom line

Enzymes are a "depends," and the source settles the question. Microbial and plant enzymes are halal. Animal enzymes are halal only from an animal slaughtered the Islamic way, and enzymes from pigs are haram. Most food enzymes today come from microbes. When an animal source is possible and the label says nothing, look for a "microbial" or "vegetarian" statement or a halal symbol.
