Loquat fruits begin appearing
in the trees by the end of winter season. Mature fruits are ready to
harvest by June in Japan, however their harvesting season may vary from
region to region. The fruits are oval to pear 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 in
the tree before harvesting. Ripen
fruits have soft texture. Externally, the skin surface is
fuzzy but smooth
with golden-yellow to orange color. Internally, the flesh is
either white or orange in color depending on the cultivar
type. Each fruit contain 3-5, centrally placed large, brown
seeds. The seeds are inedible and may contain toxic cyanogenic
glycosides.
Being a member of rosaceae family, the fruits
have taste and
flavor similar to apples; tart, sweet with pleasant aroma. Loquat's
leaves are also used in traditional medicines and as herbal
tea in many parts of the world.
Health benefits of Loquat fruit
- Delicious, loquats are
very low in calories; provide just 47 cal per 100 g, but rich
in insoluble
dietary fiber, pectin.
Pectin retains moisture in the colon and thus functions as bulk
laxative. This way it helps to protect the
colon mucous membrane by decreasing exposure time to toxic substances
as well as binding to cancer causing chemicals in the
colon.
- Pectin has also been shown
to reduce blood cholesterol levels by
decreasing re-absorption of cholesterol binding bile acids in the
colon.
- Loquat fruit is an
excellent source of vitamin-A
(provides about 1528 IU per 100g), and
phenolic flvonoid
antioxidants
such as chlorogenic acid, neo-chlorogenic acid, hydroxybenzoic
acid, feruloylquinic acid, protocatechuic acid,
epicatechin, coumaric acids and ferulic acid. Ripen fruits
have more chlorogenic acid concentrations.
- Vitamin A maintains
integrity of mucus membranes and skin. Lab studies have shown that
consumption of
natural fruits rich in vitamin-A and flavonoids helps to protect from
lung and oral cavity cancers.
- Fresh fruit is
very rich in potassium and some B-complex vitamins such as folates,
vitamin B-6 and niacin and contain small amounts of vitamin-C.
Potassium in
an important component of cell and
body fluids, helps controlling heart rate and blood pressure.
- It is also a good source
of iron, copper, calcium, manganese and other minerals. Manganese
is used by the body as a co-factor for the antioxidant enzyme superoxide dismutase.
Copper is required in the production of red blood cells. Iron is
required for as a cofactor in cellular oxidation as well for red blood
cell formation.

Selection
and storage
Loquat fruit season begins by late winter months to early spring.
Generally, fruits are harvested once they turn yellow and become soft
in texture; carefully picked up from the bunch to avoid
injuries.
In the store,
buy fresh ripe fruits featuring bright yellow color; smooth
surface and emanate
mild but sweet aroma. They should be devoid of
any wrinkles, cuts and patches on the skin. Avoid overtly
soften fruits with spots as they
tend to perish early.
Loquats keep
well for up to 2 weeks in the fruit/vegetable compartment of the home
refrigerator.
Preparation
and serving method
Wash loquats under cool water before consuming to remove any surface
dirt
or pesticide residues.
The pulp just underneath the skin is sweeter than central tart pulp.
The skin of the loquat is easily removed. Peeled fruits are eaten fresh
or mixed with other fruits like banana, mango, and orange as
salad.
Here are some serving tips:
- The Fruit sections are a great addition to
fruit salads.
- They are also used in desserts or as
pie-filling, or are chopped and cooked as a sauce.
- Loquat fruit is also made into jam, jelly and
poached in sugar syrup with a cinnamon to make delicious loquat
fruit syrup.
