A process for preparing a dehydrated carbohydrate-containing nutritional product comprises preparing a liquid concentrate with a reduced carbohydrate content, spraying the liquid concentrate into a spray-drier and incorporating the remainder of the carbohydrate content into the nutritional product by blowing solid carbohydrate particles into the spray dryer and removing the carbohydrate-containing nutritional product from the spray-drier. The process substantially reduces the problem of fouling of the spray dryer
