How to check ripeness of star apples?
Star apples come in three colors, the most common being a purple variety. Others, however, are green and sometimes yellow. The purple variety goes from green to purple—sometimes a green blush lingers on a soft, ripe fruit. Green varieties, however, require touching them in order to determine their ripeness—if hard, they’re unripe. If pliable and slightly rubbery, they’re ready for consumption. Yellow variants are most rare of all, but they turn from green to yellow and grow soft when ripe. Select bright, shiny fruits with no bruises or visible damage.

Scientific proven health benefits of Star apple/ Star plum
• Polyphenolic Antioxidants / Fruits
Study on various fruit extracts yielded nine known phenolic antioxidants. The ethyl acetate soluble fraction displayed the highest antioxidant activity, and of the compounds, compound 5 (quercetin) showed the highest antioxidant activity.
Including quercetin, quercitrin, isoquercitin, myricitrin, catechin, and gallic acid. Some of these antioxidants, such as quercetin, have well-known health benefits including being anti-cancerous, anti-asthma, and a regulator of metabolism.
• Vasorelaxant (Reduction in tension of the blood vessel walls)
A preliminary study on the relaxant effect of the crude extract and fractions of the bark of Chrysophyllum cainito L. in isolated rat thoracic aorta: Methanolic bark extract study on rats showed vasorelaxant activity on the smooth muscle.
• Antidiabetic Activity / Leaves
Study of the aqueous decoction of C cainito leaves showed hypoglycemic activity at doses of ≥ 20 g/l. From 30 g/l, the plant would exert a toxic effect. The hypoglycemic effect was mainly attributed to alkaloids, sterols, or triterpenes.
• Hypotensive Effect (lowers blood pressure)
Phytochemical study attributes the hypotensive effect flavonoids with vasodilation effect and inhibition of adrenergic receptors.
• Anti-Inflammatory / Anti-Hypersensitivity Effects / Leaves
Study of crude methanolic extract of leaves demonstrated anti-inflammatory and anti-hypersensitivity effects on carrageenan-induced paw edema and hypersensitivity. Reduction of hypersensitivity attributed to isolated compound Lup-20(29)-en-3β-O-hexanoate > than 3β-Lup-20(29)-en-3-yl acetate. It could be effectively used in the management of persistent inflammatory and neuropathic pain in humans.
How to eat or cut star apples?
Fruit eaten ripe, with a sweet and flavorful pulp. Eat star apple like a persimmon: wait until the fruit is soft, and then press gently along the sides. Next, split the fruit in half with the fingers or cut with a knife, and eat the gelatinous, juicy flesh. Spit out the three to eleven flat black seeds.
Another common method of eating a star fruit is by enjoying it as one would a kiwi: by cutting in half and scooping the flesh with a spoon. Try not to scoop too close to the skin, as this will release latex into the fruit.
