Blueberries ripen over a period of several months and keep remarkably
well. Fresh blueberries are extensively used as food and are also canned
and frozen, and after preservation are used commercially in the bakery,
preserve, and jelly industries.
The blueberry is a North American native fruit that belongs to the Vaccinium genus from the Ericacea
family, characterized mainly by a high content of antioxidants such as
polyphenols and vitamin C. Scientists reported that fresh blueberries
contained 6.3 mg/g of vitamin C.
Vitamin C –an antioxidant that is needed to stop free radicals from
doing harm in human bodies. Free radicals form in human bodies from
activities that we do everyday like being out in the sun or breathing
air with pollution. They promote aging and disease. Blueberries have 38%
more free radical fighters or antioxidants than red wine.
Vitamin C is readily oxidized, especially in the presence of metal
ions such as copper and iron. Heat and light accelerate the process,
while additional factors such as oxygen concentration, pH and
water activity strongly influence the rate of the reaction.
