FOOD COLORING & APPLICATION

Color Reference For Your Order

There are two main types of colors:

Natural and Synthetic

          Natural and Synthetic

1) Natural Colours.

Natural Colours are extracted from natural matter such as plants, trees and insects. The disadvantage of Natural Colours is that they are:
a) More expensive.
b) Less stable.
c) Weaker

2) Synthetic Colours.
Synthetic colours are manufactured by the ton in batch lots, the most common of which is the AZO DYE (-N=N-). There are hundreds of AZO DYES, which can produce virtually every colour required. Only a handful of these colours have FDA (Food and Drug Administration) approval. The basic colours are two shades of Red, two shades of Blue, a Yellow and an Orange. Other FDA colours are available, but with these basic colours in varying strengths and combinations, virtually every colour can be formulated.

     Primary & Lake colours

  1. There are two types of Food Colours: Primary and Lake

    1) Primary Colours. .
    Primary Colours are water-soluble and usually used for wet applications.
    2) Lake Colours.
    Lake Colours impart their colour by dispersion. Lake Colours are manufactured by adsorbing the Primary colour on to Aluminium Hydroxide. This is then dried and very finely milled. Lakes are generally used in Dry Applications where finely divided particles of lake, form a coating on the surface of the product.

Why food Colour?

If food does not taste good, people will not try it again. If it doesn’t look good, people may not try it at all. To understand why natural colors are so important for improving the visual appeal of food and beverage products, it is helpful to understand the science, psychology and history of colour.

The Science of Color

The science of color is sometimes referred to as chromatics, colorimetry or color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnectic radiation in the visible range — commonly referred to as “light.” The color wheel can be divided into warm colors (those associated with the colors of the sun, such as red, yellow and orange) and cool colors (those associated with night, such as blue, purple and green). There are also three primary colors used to make all other colors: red, yellow, and blue. Secondary colors can be created by blending combinations of red, yellow or blue together to achieve orange, green or purple. This same color psychology phenomenon was also reported by the Journal of Consumer Research (March 2007), which found that consumer taste perceptions were directly influenced by beverage color. In fact, color was more influential in consumer product preference than price or even product quality — stunning evidence of just how important color is! In the March 2010 issue of Chemosensory Perception, it was reported that food color does indeed influence a food or drink’s taste and flavor perception in humans. “People’s judgments of flavor identity are often affected by the changing of a food or drink’s color (be it appropriate, inappropriate, or absent).”

Food Colors - Origins and Chemistry

Food colours are divided into 3 main types:

Natural, Nature Identical and Synthetic

Natural Colours

Natural Food Colours are dyes or pigments extracted from natural sources like vegetables, plants and insects. If extracted with care, these Colours can provide versatile colouring application with safe usage in different types of Food Products. Since last 25 years, Tanya has been manufacturing Natural Food Colours made strictly from plants and vegetables which serve the needs of a variety of Food and Beverage Industries. These colours are used to give visual appeal and colour uniformity & consistency to Food and Beverages.These are obtained from natural sources such as grasses, leafy vegetables, fruit skins, roots and seeds of plants. Animals can also be a source of food colourings. Cochineal, or carminic acid, is a red colour that is obtained from the bodies of certain scale insects. These feed off cactus leaves and their bodies are commercially harvested in Africa, Spain and Central America. Their bodies are dried and crushed to extract the red coloring.

Nature Indentical Colours

Obtaining colors from natural sources can be costly and their quality can vary. To overcome this, chemists have found ways to make identical colors in the laboratory. This improves their purity and may also cost less Nature identical colors are exactly the same molecules found in natural sources but they are made synthetically. The main chemical classes are: flavonoids, found in many flowers, fruits and vegetables indigoid, found in beetroot carotenoids, found in carrots, tomatoes, oranges and most plants. Carrots contain an orange molecule called beta-carotene which is part of this group. Most natural and nature identical colors can dissolve in oil but do not dissolve in water. This means it is difficult to add them directly to foods. They are usually processed to form their sodium or potassium salt. This makes them soluble in water and suitable for use in foods. They may also be dissolved in oil and incorporated into water-soluble beadlets.

Synthetic Colors

The basic application synthetic food colors or artificial food colors include coloring of food items, pharmaceutical and cosmetic industries. personal care products, dairy products, confectionary, bakery, sweet meats etc. These food colors are also known as food dyes, food additives, food ingredients, food lake color, blended food color etc. Synthetic food colors are formulated and manufactured in accordance with the International food color quality standards. These are colors that do not occur in nature and have been made in a factory. They have been carefully tested to make sure that they are safe. The main examples of synthetic colours are: azo dyes, such as amaranth (colour for blackurrant jams). ‘other’ dyes, such as, quinoline, (quinoline yellow), xanthene, (erythrosine), triarylmethanes, indigoid, (indigo carmine). Synthetic colors are usually water soluble and can be used in foods without any further processing.
