E631 : Sodium inosinate
Sodium salt of inosinic acid (E630), a natural acid, that is mainly present in animals. Commercially prepared from meat or fish (sardines). May also be produced by bacterial fermentation of sugars.
Function & Characteristics:
Flavour enhancer. Inosinic acid and inosinates do not have the specific umami taste but strongly enhance many other flavours, thereby reducing the amounts of salt or other flavour enhancers needed in a product.
Used in many products.
Acceptable daily intake (ADI):
None determined. Inosinates may not be used in products intended for children under 12 weeks.
Asthmatic people should avoid inosinates. As inosinates are metabolised to purines, they should be avoided by people suffering from gout. However, the concentrations used are generally so low that no effects are to be expected.
Inosinates are generally produced from meat, but partly also from fish. They are thus not suitable for vegans and vegetarians, and in most cases not suitable for Jews, Muslims and Hindus, depending on the origin of the product. Only the producer can provide information on the origin.
Regarding the issue of E631 in Lays products in Pakistan we would like to refer to the Lays Pakistan Statement and the certification of Halal of Lays products. The inosinate is made from tapioca starch and no animal products are involved in the production.
