Grape Skin Extract is a product that in most parts of the world is used as a by-product for wine or juice production. These grape skin extracts are a great and abundant source for inexpensive anthocyanins that are used in the coloring of food and beverages. The skin of the grape is obtained through aqueous extraction of the grape after the juice has been expressed. As the pH levels shift the hue of the product shifts from red with low levels and blue with higher pH levels. It is often blended with other anthocyanins in novel beverages to enhance the fruity appearance of drinks.

Beta-Carotene (Natural) is a carotenoid food coloring that ranges from yellow to orange depending on its concentration. It is used to enhance the visual appeal of juice drinks, tropical beverages, and even desserts. Natural beta-carotene performs equal or better coloring compared to conventional (synthetic) beta-carotene.
Black/Purple Carrot is an anthocyanin that works for colouring in many types of food and beverage applications and are grown mostly in southern Europe and Asia. These pigments exhibit a reversible change in molecular structure as the pH of solutions change from acidic to basic. This change in structure is characterized by a shift in hue from red to purple to blue as the pH changes from acidic to basic. Anthocyanins from purple carrots are more stable over a wider pH range than most anthocyanins making them ideal for yogurts and other dairy products.
Burnt Sugar is a light to dark brown liquid or powder obtained from the controlled heating of sugars used primarily for flavouring and/or sweetening with incidental colour. Consumers in many regions continue to demand natural foods. In response, food and beverage manufacturers are formulating with simple, clean label options — including “Burnt Sugar” and “Colour: Plain Caramel.” Applications include baked goods, breakfast cereals, dessert toppings, sauces, seasonings, coffee drinks and confectionery products.
Calcium Carbonate is a white powder found in nature in mineral sources such as calcite, limestone and marble. It adds color to foods and firming properties to vegetables. It is insoluble in water but may be emulsified to disperse in water. It may be produced by the precipitation of calcium ions with carbonate ions. The European Union (EU) has approved calcium carbonate as a food coloring. Some other regions do not allow its use as a color additive.
