This invention provides processes and apparatus for enhancing the nutritional value of food products. Nutrition-enhancing agents are applied or dispensed onto or into food products during their manufacture by food-grade controlled-droplet dispensing heads (or head). In preferred embodiments, the dispensing heads are controlled by a controller, such as a programmed PC-type computer, in dependence on sensor data, such as electromechanical, optical, or image sensor data. The controller and sensors operate so that different food items can have selected nutrition-enhancing agents properly applied or dispensed without waste or overspray. The invention also provides food products which have been enhanced according to the provided processes and apparatus with nutrition-enhancing agents.
