Unfinished crystallisation in freshly produced chocolates is one of the major reasons for fat bloom, especially for filled products. Chocolate shells, if insufficiently crystallised, show reduced resistance to oil-migration of fillings. The influence of two production parameters, cooling tunnel time and storage temperature, on the finished state of chocolates is investigated. It is found that the crystallisation in the chocolates is not finished when the products leave the cooling tunnel.
