String beans, also known as green beans and snap beans, might not seem like your standard juice ingredient. However, these vegetables are packed full of nutrients and, while unpleasant to drink on their own, including the beans in your favorite juice blend can boost the nutritional content without drastically changing the flavor. String bean juice can also help you meet your daily vegetable intake recommendation for a healthy diet.

Juicer or Blender

String beans, because they are very fibrous, benefit from being juiced in a juicer. All juicer types, including centrifugal and cold-press juicers, can juice string beans. A juicer separates the insoluble fiber from the liquid naturally found in string beans. While this lowers the overall dietary fiber content, string bean juice from a juicer will still contain a significant amount of soluble fiber. String bean juice made in a blender, even a high-powered blender, will still leave small bits of unprocessed vegetable, creating an unpleasant texture.

Juicing Technique

Prior to juicing your string beans, wash and trim the beans, cutting off any discolored or soft portions. Even if the beans are pre-washed, it is best to give them a rinse before using to be on the safe side. Insert the beans into the feeding tube at the top of the juicer. Use the included plunger to push the beans into the spinning centrifuge. Never use your fingers or another utensil. The juice will be extracted from the beans, and will come out from the juice spigot. Place your glass or the juicing cup underneath to catch all drops of liquid.

Taste and Blends

Pure string bean juice has a very strong grassy taste that is usually too strong to be consumed on its own. However, it makes an excellent addition to a green juice — such as a kale, spinach and apple juice — where the muddy green color of the juice will not have a disconcerting affect on the juice’s appearance. String bean juice can also be added to blender juices, such as a berry juice, where the dark color of the fruits masks the green shade of the juice.

Because string bean and other vegetable-heavy juices are grassy tasting, sweet fruits or vegetables, such as apples, pineapples or beets are often included in the juice blend to make them more palatable. To mask the bitterness that can come from green juices, include a few drops of fresh lemon or lime juice.

Store Fresh Juice

Fresh juice and juice blends are best consumed soon after making. However, they can also be stored in a sealed or covered food-grade container for up to three days. The longer the juice is stored, however, the more it deteriorates in both nutrients and taste. Fresh juice can also be frozen for up to two months, maintaining a taste similar to fresh juice, but the nutritional content may be altered.
