Question

What is the antioxidant content in some common fruits?

ANSWER

Most of the fruits contain good dose of natural antioxidants. Antioxidant can be defined as the ability of a bioactive compound to maintain cell structure and function by successfully clearing free radicals, retarding lipid peroxidation reactions, preventing other oxidative damage and also many other biological functions, such as anti-cancers, anti-inflammation and anti-aging (Zou et al., 2015).

Type of Fruits Antioxidant mmol/100g
Strawberry 2.05
Guava 1.21
Orange 1.08
Papaya 0.76
Apple 0.51
Mango 0.33
Banana 0.27
Pear 0.22
Watermelon 0.18

Discussion:

By referring to Table 1, the highest antioxidant content can be found in Strawberries (2.05mmol/100g), while the lowest is in watermelon (0.8mmol/100g). Strawberries, which belong to the family members of berries called Rosaceae has the best sources of bioactive compound and possess high antioxidant capacity such as ascorbic acid, phenolic acid, anthocyanins and flavonoids (Skrovankova et al., 2015). Moreover, Carlsen (2010) also reported that, average antioxidant content in berries and berry products is relatively high ranging from 0.06mmol/100g in Elderberry drink to 261.5 mmol/100g in the dried Amla berries, compared to fruits and fruit product ranging from 0.02mmol/100g for watermelon to 55.5mmol/100g respectively. Thus, strawberry is the highest antioxidant content compared to other common fruits chosen.
