The trick is in the packing. Tetra pak is a kind of sterile packing which allows food to be stored without preservatives without spoiling. The same goes for carton milk.

Once I visited Duke Factory in Mumbai. There I saw the bottled drinks were being subjected to process call pasteurization. If fruit drinks require a 'Shelf life' of 7, 10, 14 or up to 16 days then instead of adding preservatives they can be simply pasteurized. Pasteurization process was named after Louis Pasteur who discovered that spoilage organisms could be inactivated in wine by applying heat at temperatures below its boiling point. The process was later applied to milk and remains the most important operation in the processing of milk. Now it is being applied to fruit drinks as well.

Dear Gem, Not sure how Tropicana etc. preserve their fruits juices, but for your garden fruits you can use a sugar. Lots of sugar (or even salt) ensures that water can not spoil your natural ingredients. Remember to protect the juice / jam etc. from water after that. The process used here is osmosis which is also used in making pickles.

Personally, making fresh juices ourselves at home would be the best choice. This will ensure that we are getting what we want but we do not do so for many reasons.
Those added additives are added basically to have a longer shelf-life and for retail purposes, otherwise, juices frshly squeezed for that purpose will not taste the same from time to time.
