Loquat fruits begin appearing in the trees by the end of winter season. Mature fruits can be ready to harvest by June in Japan; however, their harvesting season may vary from region to region. The fruits are oval to pear in shape, appear in bunches of 5-20, and measure about 3 cm in width and 3-5 cm in length.

In general, the fruits are allowed to ripen on the tree itself before harvesting. Ripe fruits have a soft texture. Externally, its yellow to orange color skin is fuzzy but smooth. Internally, the flesh is either white or golden yellow depending on the cultivar type. Each fruit contains 3-5, centrally placed large, brown seeds. Seeds are inedible and may carry toxic cyanogen-glycosides.

Being a member of Rosaceae family of fruits, loquats have similar taste and flavor as that of apples; tart, and sweet with a pleasant aroma. However, they are soft and juicy in texture instead of crispy as in apples. Loquat's leaves also employed in traditional medicines, and as herbal tea in many parts of the world.

Health Benefits of Loquat fruit

  • Delicious, loquats carry lower calories; provide just 47 calories per 100 g. Nonetheless, they are rich in insoluble dietary fiber, pectin. Pectin holds back moisture inside the colon, and thus functions as bulk laxative. This way, it helps protect the colon mucosa by cutting exposure time of toxic substances as well as binding to cancer-causing chemicals in the colon.

  • Pectin has also been shown to reduce blood cholesterol levels by lowering its reabsorption in the colon through binding bile acids, resulting in its excretion from the body.

  • Loquat fruit is an excellent source of vitamin-A (provides about 1528 IU or 51% of daily recommended levels of this vitamin per 100g), and phenolic flavonoid antioxidants such as chlorogenic acid, neo-chlorogenic acid, hydroxybenzoic acid, feruloyl quinic acid, protocatechuic acid, epicatechin, coumaric acids and ferulic acid. Ripe fruits have more chlorogenic acid concentrations.

  • Vitamin-A helps maintain the integrity of mucosa and skin. Lab studies suggest that consumption of natural fruits rich in vitamin-A, and flavonoids may offer protection from lung and oral cavity cancers.

  • Fresh fruit is good in potassium and some B-complex vitamins such as folates, vitamin B-6 and niacin and contain small amounts of vitamin-C. Potassium is an important component of cell and body fluids that helps to regulate heart rate and blood pressure.

  • Furthermore, the fruit is also an excellent source of iron, copper, calcium, manganese, and other minerals. The body uses manganese as a co-factor for the antioxidant enzyme, superoxide dismutase. Copper is essential in the production of red blood cells. Iron is required for as a cofactor in cellular oxidation as well in red blood cell formation.
