The constituents of a soft drink

as the main component of a soft drink, usually accounts for between 85 and 95% of the product and acts as a carrier for the other ingredients. Its quality must conform to rigid requirements and not interfere with the taste, appearance, carbonation or other properties of the drink. Subject to the location of the bottling plant, the source of water and product specifications, it may be necessary to carry out treatment to improve the quality of the water used in the manufacture of soft drinks. 

In most urbanised areas of the world, public water supplies can meet consumer requirements of potabihty, but for the soft drinks manufacturer this is not always a suitable qualification for use of the water as a raw material. Most soft drinks factories will carry out their own treatments to counteract the likelihood of a possible change in quality. This is most important in areas where variations are introduced as a result of the use of a national grid system for water supply. 

In less developed countries, water treatment becomes an essential prerequisite where microbial loading could provide cause for concern. It is necessary for a full water treatment to be effective and to ensure the wholesomeness of water supplies for boiling ptuposes. 

Water should comply with the following quality requirements. It should be free from 

Ideally, a non-variable supply of water should be available at all seasons of the year to allow a standard manufacturing process to be established.
