Roselle juice

Roselle juice, known as bissap, wonjo, foléré, dabileni, tsobo, zobo, siiloo, soborodo or Sobolo in parts of Africa, sorrel in the Caribbean, and agua de Jamaica in Mexico, is a drink made out of the flowers of the roselle plant, a species of Hibiscus. Although generally the "juice" is sweetened and chilled, it is technically an infusion and when served hot can also be referred to as hibiscus tea.

Description
Roselle juice, often taken refrigerated, is a cool drink found in many West African countries and the Caribbean. It is a dark red-purple coloured juice. The Burkinabes, Senegalese, and Ivorians call it bissap, the Nigerians call it zobo while the Ghanaians call it Zobolo. It tastes a bit grapey and a little like cranberry juice and can be served with mint leaves. It can also be served with any flavouring of one's choice — sometimes with orange essence or ginger, pineapple juice, tea grass, vanilla, and many others. In Ghana, Nigeria, and Senegal, roselle juice is served cold, while in Egypt, it is served warm.

Preservatives
There are two types of preservatives used in production of zobo tea, the natural ones are the nutmeg, lime and cloves which keeps the drink fresh.

Sodium benzoate at a concentration of 0.1% or mixture of citric acid and magnesium sulfate are the chemical compounds used in preserving zobo drink for a longer time and make it carbon-free. The artificial preservatives are neutralized with fruit juice in order to conserve the sour taste of the leaf during production.
