Embodiments related to juicing methods and apparatuses for extracting juice from food matter using juicer cartridges are described. In one embodiment, a juicer cartridge (200) may include one or more separate internal compartments. Food matter loaded into the juicer cartridge (200) may be compressed by a corresponding juicer (100) and expelled through an outlet (220) that may be sealed until activation. Food matter may be pre-sized according to various physical characteristics, and the juicer cartridge may be injected with a gas to enhance shelf life and reduce nutrient loss. The juicer may also be provided with "smart" functionality to provide safety features, track usage, and enhance the operator experience. Several embodiments of packing systems for preparing juicer cartridges are also described.
