In a method for upgrading for human consumption of fresh produce, in particular vegetables or fruit, an enriching agent is added to the fresh produce and the fresh produce with the enriching agents is processed to an end product ready for human consumption. The enriching agent comprises a chlorophyll-containing vegetable and/or fruit mixture appropriate for the fresh produce with a basic component which is formed by a minimum mass of 35% of at least one chlorophyll-containing vegetable. The fresh produce is ground together with the mixture, optionally with the addition of a liquid, to form a drinkable mass. The mixture is particularly supplied and applied here as enrichment kit in a packaging.
