Masticating juicers mimic “chewing” fruits and vegetables using augers with sharp metal teeth. They then press the maximum amount of juice from the pulp resulting in high yields and very little foaming or oxidization. This technique allows for easy juicing of leafy greens such as wheatgrass, spinach, and kale. Also known as “slow” or “cold-press” juicers, these models take more time to produce juice but don’t heat it up, which is thought to preserve more nutrients. They tend to be quieter and operate at a low hum. Their stronger motors come at a higher cost but enable additional features like making nut butters, baby food, sorbets, and even pasta. Masticating Juicers cost upwards of $200 and are more of an investment for the serious juicer.
