Mustakshif Shariah Board Rulings on E1105

According to Mustakshif Shariah Board, E1105 is classified as Mushbooh. According to many halal certification bodies, lysozyme is considered halal when it is sourced from eggs produced by halal-certified farms and processed according to halal guidelines. While concerns may arise due to a lack of transparency in commercial sourcing, when lysozyme is obtained from eggs that are not contaminated with haram substances and the production process meets halal standards, it is deemed permissible (halal) for consumption in Islam. As always, choosing products with halal certification helps ensure compliance with Islamic dietary laws.

Introduction

E1105, also known as Lysozyme, is a food additive used primarily as a preservative and antimicrobial agent. It is commonly referred to by its chemical name or simply as muramidase. Lysozyme works by breaking down bacterial cell walls, which helps extend the shelf life of various food items.

Source and production

Lysozyme is a natural enzyme, usually extracted from egg whites, particularly from hen eggs. In some rare cases, microbial or recombinant sources may be used, but egg-derived lysozyme is the most common form used in the food industry. The enzyme is separated, filtered, and then purified before being added to food products.

Usage

Lysozyme (E1105) is widely used in the dairy industry, especially in cheese production, to prevent spoilage caused by unwanted bacteria. It is also used in wine-making and some processed meat products to control microbial growth. Its main function is to act as a preservative, extending product shelf life without altering taste or texture.

Conclusion

E1105 (Lysozyme) is effective in preserving food but raises concerns due to its egg-based origin. Its halal status is uncertain unless verified. Muslims should look for halal-certified labels when choosing products containing this ingredient.
