The present invention relates to encapsulated lactic acid, where lactic acid is in a solid, pure, crystalline form. The encapsulation of food acids is common practice. Many companies produce encapsulated citric, tartaric and sorbic acids or GDL. However, lactic acid, a major food acid for its flavour and conservation effect, is not available in a pure solid crystalline encapsulated form. As no substrate is needed for said coated solid lactic acid particles, the lactic acid content of said particles may be very high and the activity of the lactic acid is not impaired by the substrate. Furthermore, the encapsulated solid lactic acid particles according to the invention are easy to handle and are less expensive than encapsulated liquid lactic acid.
