Origin of jujube fruit

Jujubes are believed to be one of the oldest cultivated fruits in the world and can be traced back 7,000 years to the Neolithic age in China. Jujubes fruits are referred to in one of China’s oldest poetry books, The Book of Songs, which dates back to approximately 3,000 years ago. This fruit was used in Traditional Chinese Medicine to promote relaxation and proper sleep. Over time, it traveled to neighboring countries of Southeast and South Asia. Today, it remains an important crop in China, Korea, India, Australia, and Middle Eastern countries.

Nutrition

Jujube fruits are rich in bioactive compounds, such as ascorbic acid, triterpenic acids, phenolic acids, amino acids, saponins, cerebrosides, flavonoids, and polysaccharides. Jujubes also contain vitamins and minerals such as potassium, nitrogen, calcium, phosphorus, iron, manganese, copper, and zinc. These components give the fruit antioxidant, anti-inflammatory, and antimicrobial effects. Jujubes are also known to help prevent cancer, cardiovascular diseases, gastrointestinal diseases, and diabetes.

Commercial production

There are currently almost 1,000 different jujube fruit varieties that are commercially grown. Jujubes grow best in climates with hot and dry summers and sufficient rainfall. However, they grow well even under harsh conditions because of their low water requirement and high salt tolerance. It is a great desert plant and is even drought resistant. The tree prefers sandy loamy soils, but also grows well on heavy clay soils.

Fresh jujubes must be consumed within 2-3 days. However, they can last for up to three months, if kept in an airtight container in the fridge. Dried jujubes can be stored for up to one year, if kept in a cool and dry place. Recent studies have found that jujube flour can increase the shelf life of products like sponge cake.

FDA regulations
