I love star fruit, but they go bad quickly once they ripen. I found this perfect solution of dehydrating them, and they are delicious dehydrated! I like the Excalibur dehydrator. My dehydrator is large, so I can do many starfruit at one time. I usually chop them in thin slices and then heat them at 120 degrees Fahrenheit from 12- 14 hours. I dehydrate them with seeds and everything, and they taste great!
Star fruit is one low calorie exotic fruits: 100 g fruit is only 31 calories! The fruit has 2.8g of dietary fiber, which helps prevent absorption of dietary LDL (bad) cholesterol and binds to carcinogenic chemicals in the colon. Star fruit provides 57% of daily recommended levels of vitamin C, which helps the human body develop resistance against infectious agents and scavenge inflammatory free radicals from the body. It is also rich in antioxidant phyto-nutrient polyphenolic flavonoids, which help protect the body from oxygen derived free radicals. In addition, it is a good source of B-complex vitamins such as folates, riboflavin, and pyridoxine (vitamin B-6), which are co-factors for enzymes of metabolism. Star fruit also has minerals and electrolytes like potassium, phosphorus, zinc and iron.
People with known kidney disease should avoid eating star fruit because eating star fruit could cause renal failure, resulting in death. Star fruit is one of the plant sources that contain highest concentration of oxalic acid. Oxalic acid can interfere with absorption and metabolism of several natural minerals such as calcium and magnesium and may lead to the formation of oxalate kidney stones.
Star fruit also has been found to interact adversely with many drugs. Some of the compounds in carambola irreversibly inhibit cytochrome P450 3A4 isoenzymes in the intestines and liver. Therefore, consult your doctor before eating star fruit or its products if taking any kind of medications. 365 Days of Graceful Living will not be held liable for ill effects of consuming star fruit.
