I’m often asked if it’s okay to freeze your juices and smoothies, and believe it or not, freezing juices or smoothies in mason jars, ice cube trays, or popsicle molds is a great option, especially if you want your juice etc. to last more than 24 hours. Freezing actually preserves most of the nutritional value of fresh juice and smoothies.

The longer your juice sits in the fridge, the longer it’s exposed to oxygen—causing nutrient degradation and the loss of enzymes. Keep in mind that for juice, the rate of degradation depends on the type of juicer used. Juice made with a centrifugal juicers have a shorter shelf life than juice made with masticating, twin gear or hydraulic juicers.

Here’s a handy chart showing what percentage of nutrients is lost during freezing (and cooking, reheating, etc.). It’s important to let your frozen concoction thaw naturally and drink it right away, or have it frozen. Nothing like a green smoothie popsicle on a hot, summer day! Heating or defrosting these nutrient-dense creations in a microwave will degrade the nutrients even more.
