Food enrichment vs. fortification

Many a times we come across these terms on packets of food items and get confused, as more or less they seem to mean the same. Food enrichment is in fact the addition of nutrients so as to restore the amount lost by processing, storage etc. For example, addition of vitamin C to orange juice in order to compensate for the loss due to processing etc. is enrichment. On the other hand, fortification is the addition of those nutrients to food items that was not naturally present in them. Addition of Iodine to common salt is therefore an example of food fortification.
