Juice processing technology

Description

A wide range of drinks can be made using extracted fruit juice or fruit pulp as the base material. Many are consumed as 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 uses. 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. There are several methods to extract juice depending on the type of fruit you use. For citrus fruits which are naturally juicy, the best option is to use a hand presser or a revolving citrus ‘rose’. Some fruits such as melon and papaya are steamed to release the juice. Apples are pressed and fruits such as mango, guava, soursop, pineapple and strawberry must be pulped to extract the juice. The fruit pieces are pushed through a perforated metal plate that crushes and turns them into a pulp. This book sheds light on this subject in detail while also being informative for general readers.
