Natural Green Food Colour
Green-coloured foods are abundant in nature, with strong association to a healthy diet due to the vitamins and minerals found in green foods like herbs and vegetables.
The green colour is imparted by chlorophyll, a natural compound crucial for photosynthesis. Chlorophyll is naturally oil-soluble, but can be modified to the water-soluble equivalent Chlorophyllin, and further modified if desirable to Copper Chlorophyll/Chlorophyllin to create a brighter and more stable natural food colour.
Green colour for foods and beverages is extracted from edible plant material such as grass, alfalfa and nettle, and it available in liquid or powders forms. For more clean label, a ground herb powder or vegetable juice blend can also be used for colouring.
When green fruit flavours such as apple, grape, lime or kiwi are used in beverages or confectionery, a green colour should be present in order to maximise the gestalt of flavour perception. In any nutrition-focused beverage/food a strong green colour will help to visually establish its health credentials.
