Food additives may come from natural and chemical sources. In some countries, this ingredient is coded
into e-numbering system. E-Number identifies the additive substance, and it can be used to determine
its possible sources hence the halal status and its value for health. However the use of scientific name
or the coded number is confusing to consumers. This article presents an android-based mobile
application that provides a database access to the detailed information about the additives. Information
retrieval is done based on rule-based technique. The application also offers customer profiling services
whereby upon user registration and sharing current health conditions, the consumer will be provided
with extra information on the possible consequences of consuming the food. The system prototype
system was analysed for the usability in terms of user satisfactions using System Usability Scale (SUS).
The user satisfaction is rated from good to excellent according to SUS score in the range of 70%-80%.
The application is expected to increase consumers’ awareness of choosing the right food that is halal
and healthy.
