A wide range of drinks can be made using extracted fruit juice or fruit pulp as the base material. Many are drunk as a pure juice without the addition of any other ingredients but some are diluted with sugar syrup. The types of drink made from fruit can be separated into two basic types;
Those that are drunk straight after opening
Those that are used little by little from bottles which are stored between use.
The former groups should not require any preservative if they are processed and packaged properly. However, the latter group must contain a certain amount of permitted preservatives to have a long shelf-life after opening.
