Strawberry is a small, low-lying, spreading shrub. It bears small white flowers which eventually develop into small conical, light green, immature fruits. They turn red up on maturity with each berry featuring red pulp with tiny, yellow color seeds piercing through its surface from inside. Its top end carries a green leafy cap and stem that is adorning its crown.

Each berry features conical shape, weighs about 25 grams and measures about 3 cm in diameter. The berries have the taste that varies by cultivar type, and ranges from quite sweet to acidic.

Although wild varieties are sometimes available in the market, large-scale production uses the modern "plasticulture" system. In this method, raised beds are formed each year, fumigated, and covered with plastic which prevents weed growth and crop spoiling.


Health benefits of strawberries

  • Strawberry is low in calories (32 cal/100 g) and fats but rich source of health promoting phyto-nutrients, minerals, and vitamins that are essential for optimum health.

  • Strawberries have significantly high amounts of phenolic flavonoid phyto-chemicals called anthocyanins and ellagic acid. Scientific studies show that consumption of these berries may have potential health benefits against cancer, aging, inflammation and neurological diseases.

  • Strawberry has an ORAC value (oxygen radical absorbance capacity, a measure of anti-oxidant strength) of about 3577 µmol TE per 100 grams.

  • Fresh berries are an excellent source of vitamin-C (100 g provide 58.8 mg or about 98% of RDI), which is also a powerful natural antioxidant. Consumption of fruits rich in vitamin C helps the body develop resistance against infectious agents, counter inflammation and scavenge harmful free radicals.

  • The fruit is rich in B-complex group of vitamins. It contains very good amounts of vitamin B-6, niacin, riboflavin, pantothenic acid and folic acid. These vitamins are acting as co-factors help the body metabolize carbohydrate, proteins and fats.

  • Strawberries contain vitamin-A, vitamin-E and health promoting flavonoid poly phenolic antioxidants such as lutein, zea-xanthin, and beta-carotene in small amounts. These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes.

  • Furthermore, They contain good amount of minerals like potassium, manganese, fluorine, copper, iron and iodine. Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure. 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 red blood cell formation. Fluoride is a component of bones and teeth and is important for prevention of dental caries.



Selection and storage

Strawberries can be available year-round in the stores but are fresh and plentiful from spring through mid-summer.

In the stores, choose berries that feature deep red with attached green caps, plump, shiny, free of sand and mold. Avoid those appear dull, sunken or flattened and those with signs of mold, cuts or discolored patches on the surface. Unripe berries have green or yellow patches on their surface. Since the berries cease ripening soon after their harvest, unripe berries should be avoided as they are likely to be sour and of inferior in quality. They perish early and therefore, should only be purchased a few days prior to use.

Before storing inside the refrigerator, sort out any damaged and those affected by mold so that they should not spoil healthy ones. Place them in a wide bowl or spread out on a plate covered with a paper towel. They keep fresh inside the refrigerator for a day or two. Use them as early as possible. For extended storage, place them in the freezer compartment.

To wash strawberries, dip them in cold water in a large bowl for few seconds and swish gently few times. This helps remove any sand and insecticide/fungicide residues. Then, gently pat them dry using a paper towel or cloth. This method also helps berries bring back to normal room temperature and enriches their flavor and taste. Remove stems and caps by simply sniping off with your fingers or using a paring knife.

  • Sliced fresh strawberries can be a great addition to fruit or green salad.

  • They can be a great snack between meals. Dried strawberry slices can be added in muffins, pie, cakes and are used in cereal flakes as a breakfast meal.
