how to choose food products that have been guaranteed halal status is as follows (Sharif 2009):
1. If processed food products in packaging have included MD number (registration number in the POM that shows the product produced in the country), then see if there is halal label, if there is already guaranteed because the halal status to be allowed to include in its package label kosher it must obtain a certificate halal from MUI. If there is no halal label kehalalannya it means no one guarantees.
2. For imported products, see if already have a number of ML on the packaging, if you''ve noticed the language used in the packaging, if the Indonesian language then look halal label, if there is already guaranteed halal status as number 1 above. For products imported from Muslim majority countries like Malaysia, note the halal label, if there is an existing means of ensuring its halal status. For other imported products, if there is no halal label to be avoided and we must be careful if the product is labeled halal, but produced by non-Muslim majority countries, for this case needs to ask the validity of halal label to LPPOM MUI.
3. For food products, industrial products are small, usually numbered registration of SP, is still problematic because it is still pretty much a kosher label although actually not get halal certification from MUI, partly been based on the halal certificate obtained from the MUI. This occurs because the problem of small industrial ketidakfahaman halal certification. Therefore our knowledge needed to assess whether the food products of small industries is in doubt halal status or not.
