The application relates to a method for producing a sugar product and a system thereof comprising receiving a first input in a control system representative of a pre-treatment sugar composition characteristic and/or an additive； receiving a second input representative of a post-treatment sugar product target specification； using the control system to determine at least one operating parameter for addition of the additive to the pre-treatment sugar and adding the additive based on the at least one determined operating parameter, wherein the at least one determined operating parameter is determined from at least: the first input, the second input, and a correlation relating at least the first input and the second input to the at least one operating parameter； and treating the pre-treatment sugar composition by addition of the additive to produce a post-treatment sugar product with a characteristic that is at or nearer to the target specification than the characteristic of the pre-treatment sugar composition. The system includes at least one spray system for addition of an additive to a pre-treatment sugar composition； at least one sensor for determining one or both of a pre-treatment sugar composition characteristic, or an additive characteristic, and a post-treatment sugar product characteristic and a control system configured to operate as mentioned above.L'invention concerne un procédé de production d'un produit de sucre et un système associé consistant à recevoir une première entrée dans un système de commande représentatif d'une caractéristique de composition de sucre de prétraitement et/ou d'un additif ； recevoir une seconde entrée représentative d'une spécification cible de produit de sucre post-traitement ； utiliser le système de commande pour déterminer au moins un paramètre de fonctionnement pour l'ajout de l'additif au sucre de prétraitement et ajouter l'additif sur la base du ou des paramètres de fonctionnement déterminés, le ou les paramètres de fonctionn
