6. Orange juice
For many people, breakfast isn’t complete without orange juice. People often choose 100% natural orange juice as they think it is healthier and free from artificial colouring or preservatives. However, in order to keep the oranges fresh, manufacturers remove all oxygen from the oranges in a process called ‘deaeration’. However, this removes the natural colour and flavour from the oranges. To make up for this, companies have to add artificial colour and flavouring to make the juice taste like the real thing.
