Guava is a tropical fruit that is famous around the globe for its sweet flavour and nutritional value. While the common green alternative and pink guava are household names, the black guava, which has a distinct look and potential health benefits, is a unique variety that is beginning to receive popularity. This article will focus on the origins, nutritional value, health benefits, cultivation, and uses of black guava.
What is Black Guava?
Black guava (scientific name: Psidium guajava) is a less common version of a normal guava fruit. The main distinguishing feature is its skin, which changes its colour to shades of deep purple or dark black depending on its ripeness. The flesh inside is typically deep pink or red, like the red guava, but with a richer taste and stronger aroma, which black guava is known for. Due to its rarity, this exotic fruit is grown in specific regions only and is priced a premium among guava lovers. Some experts have said that the dark pigmentation of the fruit is because of the high presence of anthocyanins, the same antioxidants found in blackberries and blueberries.
Black Guava in India
In India, black guava is one of the newly introduced fruits that is quickly garnering interest from farmers and fruit traders. With its Allahbad Safeda and Lucknow 49 selections, India is famous for variety, but black guava is not so common. It is cultivated in some specific regions where tropical conditions are prevalent. Due to rising awareness of its health benefits, the market is beginning to take notice. Further, Indian agricultural researchers and horticulturists are working to enhance its accessibility in local markets. If these efforts pay off, black guava could become the next sought-after superfruit in India’s multi-fruit market.
