Food Color

The colour of food is an integral part of our culture and enjoyment of life. Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow colour to various foods. Butter has been coloured yellow as far back as the 1300's. Today, all food colour additives are carefully regulated by authorities to ensure that foods are safe to eat and accurately labeled.
Why Are Colour Additives Used In Foods?
Colour variation in foods throughout the seasons and the effects of food processing and storage often require that manufacturers add colour to certain foods to meet consumer expectations. The primary reasons of adding colours to foods include: To offset colour loss due to exposure to light, air, extremes of temperature, moisture and storage conditions. To correct natural variations in colour. Off-coloured foods are often incorrectly associated with inferior quality. For example, some tree-ripened oranges are often sprayed with Citrus Red No.2 to correct the natural orangy-brown or mottled green colour of their peels (Masking inferior quality, however, is an unacceptable use of colours.) To enhance colours that occur naturally but at levels weaker than those usually associated with a given food. To provide a colourful identity to foods that would otherwise be virtually colourless. Red colours provide a pleasant identity to strawberry ice while lime sherbet is known by its bright green colour. To provide a colourful appearance to certain "fun foods." Many candies and holiday treats are coloured to create a festive appearance. To protect flavours and vitamins that may be affected by sunlight during storage.
