Commercial pudding powders, even if apparently similar in formulation, could result in final products with large structural differences. This aspect could be ascribed to different types and quantity of starch and carrageenans present in the formulation. Moreover, even if a large number of milk substitutes is available on the market, they can not be indifferently used for pudding production as the optimal texture of the final product is not always achieved or, in order to be obtained, it needs a proper set-up of both the formulation and the process conditions. For these reasons, the mechanisms behind the observed phenomena should be studied more in depth.
