Jujube fruit, also known as Chinese date, is an oval drupe fruit from the plant species Ziziphus jujuba. Jujube originated in China and has been cultivated for over 4,000 years for its nourishing fruits and medicinal properties. The extract and powder from this nutrient-dense fruit can provide some impressive health benefits. Read on to learn all about jujube fruit, how it’s produced, its nutritional value, medicinal uses, and potential side effects.
What is Jujube Fruit?
Jujube goes by many names - Chinese date, Korean date, Indian date, red date, and Chinese plum. It is a small, cherry-sized fruit that grows on trees belonging to the Rhamnaceae plant family. There are over 400 cultivars of jujube trees that thrive in temperate and subtropical regions of Asia, Europe, and Africa.
The fruit is smooth and oval shaped, with a single hard pit surrounded by sweet crisp flesh. Jujube skin color varies from dark red to purplish-black as the fruit ripens. The raw pulp is whitish in color and turns red or brown when cooked. The taste is like that of an apple, being sweet and tart when fully mature.
Jujube trees produce clusters of small green flowers in spring. The fruits mature in the fall over a 1-2 month harvest period. They are sold both fresh and dried. Drying concentrates the flavors and lengthens the shelf life.
Extracting Jujube Fruit
There are a few methods to extract the beneficial compounds from jujube fruit:
1. Water Extraction
This traditional technique involves simmering crushed jujube fruits in hot water and then filtering out the pulp. The resulting jujube tea retains the polar nutrients like sugars, vitamins, amino acids, and glycosides. It is a common home remedy for sore throat.
2. Ethanol Extraction
Dried jujubes are mixed with food-grade ethanol and left to allow efficient extraction of compounds like flavonoids, triterpenoids, and polysaccharides. The liquid is then filtered and concentrated under vacuum to obtain the thick, syrupy jujube extract.
3. Supercritical CO2 Extraction
This high-tech method uses supercritical carbon dioxide under pressure to selectively pull out bioactive compounds from jujubes. It yields a concentrated extract without using chemical solvents. The resulting extract retains fragile compounds.
So water, alcohol, and supercritical CO2 extraction can all produce jujube extracts with slightly differing chemical compositions suited for various end uses.
Nutritional Profile of Jujube Fruit
Jujubes are low in calories but packed with nutrients. The main active components in jujube fruit include:
- Polysaccharides - Provide anti-inflammatory and immune-boosting qualities.
- Flavonoids - Impart antioxidant and neuroprotective benefits.
- Triterpenic acids - Have calming, anti-anxiety effects.
