Citrus fruits can be used for the production of a wide range of products, but are primarily made into fruit juices.
- Orange juice
Fresh fruit is pressed and then filtered. The juice is passed through an evaporator to make a concentrate or pasteurised and sold as a freshly squeezed, non-concentrated juice.
- Lemon juice
Fresh lemons are pressed and the juice separated from the pulp. After purification the juice is processed into a concentrate.
Further processing of the juice:
- Lemon tee
Lemon juice is dried and processed into a powder with other ingredients. The powder is then moistened with water vapour. Pressing the mixture through a perforated strainer gives the granules their typical shape.
- Pulp
Pulp is the flesh of the fruit that is removed at the beginning of the juice production process. If desired, it can either be returned to the juice, or used as animal feed or as what is known as a pulpwash. A pulpwash gives many beverages the desired cloudiness. To achieve this, the pulp is leached several times, the pectin, which can be used as a gelling agent, removed and the pulp then pasteurised.
Further treatment of the rind:
- Candied orange rind/Candied lemon rind
Untreated citrus fruit rinds are boiled in a saline solution, then dried and glazed with sugar. Bitter orange is used to make candied orange rind and the white inside peel of a lemon variety low in juice is used for candied lemon rind.
