Mustakshif Shariah Board Rulings on E290 (Carbon Dioxide)
According to Mustakshif Shariah Board, Carbondioxide is considered Mushbooh (nothalal).Although carbon dioxide itself is chemically pure and not derived from animals, concerns arise from how it is sourced. Some CO₂ is captured from alcohol-based fermentation, such as from breweries, which can make it questionable for Muslim consumption.
Because manufacturers do not always disclose the specific source of carbon dioxide used in their products, it becomes difficult to determine their halal status with certainty. As a result, E-290 falls into a grey area for those strictly following halal dietary guidelines. Due to the lack of clarity around its exact origin in many food products, E-290 remains in a grey area for those following halal dietary guidelines.
Fatwas regarding E-290
There are no widely recognised fatwas specifically discussing E-290. However, some Islamic scholars note that if carbon dioxide is sourced from fermentation involving alcohol, it may not be acceptable. On the other hand, if it’s from natural or chemical sources and contains no impurities, it might be considered halal.
Ingredient overview
E-290 is the food additive code for carbon dioxide with several technical names. This compound is also known as carbonic anhydride, carbonic acid gas, carbonic oxide, or dry ice in solid form. Due to its non-reactive nature, it is widely used across the food and drink industry.
How is E-290 sourced?
Carbon dioxide for food use is typically collected through a few main methods:
- Captured from fermentation processes, such as those used in breweries.
- Recovered from ammonia and hydrogen plants, which produce CO₂ as a by-product.
- Extracted directly from natural carbon dioxide wells beneath the Earth’s surface.
- After collection, the gas is filtered and purified. Since it comes from non-living sources and involves industrial recovery, it’s classed as a processing aid and not an animal or plant-based ingredient. It functions as a preservative, leavening agent, and packaging gas in various foods.
What Is E-290 Used For?
Carbon dioxide serves several practical roles in food and beverages:
- Carbonation: It creates the bubbles in soft drinks and sparkling water, giving them a fizzy texture and a slightly tangy taste.
- Preservation: CO₂ limits the growth of mould and oxygen-loving bacteria, helping keep food fresh for longer, especially in sealed packs.
- pH Control: It slightly lowers the acidity of water and drinks, helping to balance flavours and maintain freshness.
- Leavening: In baking, carbon dioxide is released during chemical reactions (like baking soda and vinegar), helping the dough to rise and become airy.
Final thoughts
E-290, or carbon dioxide, is a gas we interact with daily, especially in fizzy drinks and packaged food. It helps preserve freshness, control acidity, and give baked goods a lighter texture. While the gas itself is clean, its halal status remains uncertain due to potential links with alcohol production. For those concerned, it’s best to confirm the source with the manufacturer or look for certified halal products.
