Awesome Healthy Benefits of Java and Water Rose Apples

The Java apple tree is an evergreen tree that bears delicious red fruits. The fruits are also known as “wax apples” due to their waxy look and brilliant red color when mature. They are used to produce sauces and are stewed with normal apples in Malaya.

Syzygium samarangense is a flowering plant of the Myrtaceae family native to the Greater Sunda Islands, the Malay Peninsula, and the Andaman and Nicobar Islands, although it was introduced to a wider region in ancient times and is now extensively spread across tropical places.

This nutritious fruit offers multiple health benefits. Apples may lower your risk for cancer, diabetes, and heart disease. Research says apples may also help with weight loss while improving your gut and brain health.


  • Syzygium samarangense is a tropical tree with evergreen leaves 10-25 centimeters (4-10 in) long and 5-10 centimeters (2-4 in) broad that can reach a height of 12 meters (39 ft). The leaves are elliptic in shape, but circular at the bottom; when crushed, they exude a lovely aroma. The trunk is quite short, with a large – yet open – crown that starts low on the tree. The tree’s bark is pink-grey in color and easily peels.
  • The flower is white-yellow-white in hue, 2.5 cm (1 in) in diameter, with four petals and many stamens. They appear as 3 to 30 spikelets at the apex of the branch. The resulting fruit is a delightful berry in the shape of a bell that ranges in color from whitish to light greenish, or greenish to reddish, purple, reddish, deep purple, or black. The fruit of wild plants is 4-6 centimeters (1.6-2.4 in) long and contains four fleshy calyx lobes at the tip.
  • The skin is thin and the flesh is white and spongy. Each fruit has 1-2 spherical seeds that are around eight millimeters in diameter (0.3 in).
  • Flower and fruit development is not limited to the axils of the leaves, but can occur on virtually any portion of the trunks and branches. When completely grown, the forest is known as a heavy bearer since it may produce up to 700 apples.
  • When the fruit is fully grown, it will inflate outward and have a little concavity in the middle of the “bell.” Wax apples with a subtle gloss are better and healthier. Despite its name, when ripe it looks like an apple from the outside. It does not taste like a regular apple.
  • It also lacks the fragrance and firmness of an apple. It has a taste similar to a snow pear and a liquid-to-flesh ratio close to a watermelon. This mesh is edible, but it lacks flavor. Its juice varies in color according to the cultivar; it might be reddish or even white.


The seeds and the Java apple

Java apples are not well-known fruits in Nigeria and other areas of the world. Those who are familiar with this fruit refer to it as a local apple or wax apple. It is a seasonal fruit, but even when it is available, it is difficult to find.

One thing I’ve seen is that many people mix up Java apple (Syzygium samarangense) with watery rose apple (Syzygium aqueum).

One time, I chose a java apple over a watery rose apple. What drew my attention was the difference in taste. The taste was unusual, but I’m glad it made me look for explanations.

  • In Indian Ocean island cuisine, the fruit is commonly used in salads and lightly sautéed dishes.
  • It is usually eaten as a fruit, but it is also used to make pickles (chambakka achar). It is known as macopa in the Philippines (before colonization, it was known as ‘dambo’). Because of its similar appearance, it is frequently mistaken with tambis (Syzygium aqueum), despite the fact that the latter is far more commonly cultivated.
  • Java apple (Syzygium Samarangense) belongs to the Myrtaceae family, Genus Syzygium, and Specie Samarangense. Within the same family and genus as;
  • Malay apple (Syzygium malaccense)
  • Watery rose apple (Syzygium aqueum)
  • Rose apple (Syzygium jambo)

Note: There are over 1200 species of this fruit(apple) and you can easily confuse one over another.

They may bear a passing similarity. They are, for example, bell-shaped, but they also have certain distinguishing characteristics.

  • A watery rose apple is shorter and lighter in body weight, but a java apple is longer and denser.


  • Watery rose apple has a softer texture than java apple, with a little sheen or waxy flesh.


  • Java apple is a regular pink color, but watery rose apple has a lighter pink color. I’ve also eaten some watery rose apple with mild purple shades.


  • In terms of flavor, java apple is juicy, sweet-sour, and mushy, similar to cashew or an old apple. Watery rose apple, on the other hand, is juicier, tastes bland, and crisp like a fresh apple.


Another contrast is the size of the seeds. The seed size of the Java apple is bigger than that of the watery rose apple.
