What Is Indian Jujube?
Indian jujube, or Ziziphus mauritiana, is a fruit-bearing tree native to South Asia and Eastern Africa. It is often referred to as 'ber' in the Indian subcontinent and is known as the 'poor man's apple' due to its high nutritional value and widespread availability. The fruit is a small, round to oval-shaped drupe that starts green and ripens into a yellow, orange, or reddish-brown color. When fresh, it has a crisp texture and a sweet, apple-like flavor. When dried, its texture becomes chewier, similar to a date.
Indian jujube contains a rich array of bioactive compounds, including polyphenols, flavonoids, and saponins, which are responsible for many of its impressive health-promoting effects. Both the fresh and dried versions of the fruit are consumed, and they can be used in various culinary applications, from fresh snacks to juices and desserts.
