The caramelization reaction is the browning of sugar during the cooking process. During the process, carbohydrates are incompletely decomposed, dehydrated and polymerized at high temperatures, and the degree is closely related to temperature and the type of carbohydrate. The final product after caramelization is a mixture of the above various dehydrated polymers. Dark brown to black liquids or solids with an odor of burnt sugar.
The Color intensity or tinctorial powder is used to describe the color strength of Caramel color. Tinctorial power, K0. The higher the Tinctorial Power, K0. Color intensity: it is defined as the absorbance of a 0. Hue index is one way to measure the redness of caramel color.
It is a function of the absorbance measured at wavelengths of and nanometers. The higher this index, the more red of caramel color. Caramel color carries ionic electrochemical colloidal charges, positive, negative or neutral depending on the manufacturing processing.
Most of the caramel color consumed today is negatively charged. Generally, the application is related to the ionic charges. This food colorant has been used in foods and beverages for over years and is globally regulated as a color additive.
Also, we can find its application in pharmaceuticals and cosmetics to impart a color from brown to red. Generally, the following foods that may contain caramel color:. The specific application is complicated, usually, there are several classes can be used in a field. There are many considerations in choosing the right caramel color for the production of beverage, such as color, PH, Vitamin C content, packaging materials protecting the colorant and so on.
Soft drinks normally carry negatively-charged molecules and therefore, a negatively-charged caramel color should be selected for soft drinks. Class IV would be suitable as it is negatively-charged and with a wide range of color intensities and shades — from reddish-brown to nearly black.
Beer requires a caramel color with a strong positive ionic charge to avoid any reaction with protein. Class III has a positive ionic charge that is stable in beer and would not precipitate out into the beverage over time. Caramel can also be used for coloring in pharmaceuticals. Yes, its safety when used as a food additive has been approved by the U. It is generally recognized as safe GRAS when used in accordance with good manufacturing practice. It is listed in Group II: Food colours authorised at quantum satis.
The following food may contain it 9 :. Functional class: Food additives, color. It is common that sometimes consumers have questions if the ingredient caramel color is bad for our health and what are the dangers. People are always afraid that the most possible health problem is regarding 4-MEI which in caramel color that may cause cancer.
The full name of 4-methylimidazole, which is formed as an impurity by the interaction of ammonia with reducing sugars, occurring in manufacturing of both Class III Ammonia Caramel and Class IV Sulphite Ammonia Caramel. California Prop 65 listed 4 Methylimidazole 4-MeI as a possible carcinogen in caramel color since as lung cancer in male mice and female mice was found with 4-MEI exposure in the study of National Toxicology Program [NTP] in FDA said there is no solid proof to believe the danger of 4-MEI caused from the use of caramel coloring in food.
To ensure the safety of using caramel color in food, the FDA is reviewing all available data and will take more action. JECFA said that the toxicity of 4-MEI was no longer a cause for concern since the concentration is limited in the specifications and the exposure to 4-MEI as a result of use of Class III and Class IV Caramel colour at the levels foreseen would be substantially below the levels found to induce neurological effects in a range of animal species in As Coca Cola said , caramel color helps give Coca-Cola its unique look and taste in its soda products:.
As a request from the buyers and end users, please be assured that caramel coloring cannot be derived from common allergens, such as starch hydrolysates from wheat , malt syrup in general derived from barley , or lactose from milk. And the manufacturers always have an allergen free list for the buyers. Although this food color is always claimed nature as it is derived from ingredients that can be found in nature. But it is not simply called natural.
But FDA indicates that it can be named as artificial color. Yes, as mentioned above, it is vegan as the raw material used and manufacturing process without the use of animal matter or products derived from animal origin. As a food ingredient, it is considered vegan and vegetarians can eat it. Yes, it is kosher and we can find some suppliers certificated with pareve.
Yes, it is gluten free or without gluten as comply with the conditions listed by the FDA that it does not contain wheat, rye, barley, or crossbreeds of these grains. It improves the appeal of food by imparting a good color.
If food looks good, people may try it. The type used in colas and other dark soft drinks is known as Caramel IV, or ammonia sulfite process caramel. Caramel III, which is produced with ammonia but not sulfites, is sometimes used in beer, soy sauce, and other foods. Five prominent experts on animal carcinogenesis, including several who have worked at the National Toxicology Program, joined CSPI in calling on the FDA to bar the use of caramel colorings made with an ammonia process.
For 4-MI, that level is 16 micrograms per person per day from an individual product. Popular brands of cola contain about micrograms of 4-MI per ounce bottle—and many people, especially teenaged boys, consume more than that each day. To put the risk from caramel coloring in context, CSPI says the ten teaspoons of obesity-causing sugars in a non-diet can of soda presents a greater health risk than the ammonia sulfite process caramel.
But the levels of 4-MI in the tested colas still may be causing thousands of cancers in the U. Those dyes cause hyperactivity and other behavioral problems in children, and Red 3 and Yellows 5 and 6 pose cancer risks, according to CSPI. Download our Ingredient and Label Statement pdf.
Although all Caramel Colors are water soluble, use in oil-based systems is possible with the right treatment. Caramel Color can be dispersed in an oil system resulting in pastes or emulsions.
Our recommendations for anyone trying to disperse Caramel Color in a non-aqueous fat system are the following procedures:. Download our recommendations for the addition of Caramel Colors in a non-aqueous fat system pdf. Domestically, the Food Chemical Codex FCC divides Caramel Colors into four classes depending on if or what food grade reactants are used in manufacture, as well as other characteristics. Europe uses Ea, b, c, or d per their definitions. Class I Caramel Colors are the most minimally processed of the four classes.
The carbohydrate raw material is simply heated, and no ammonium or sulfite compounds are allowed in Class I production. The resulting Caramel Color carries a neutral to slightly negative ionic charge. The carbohydrate raw material is heated in the presence of sulfite compounds. The resulting Caramel Color carries a negative ionic charge. The carbohydrate raw material is heated in the presence of ammonia compounds.
The resulting low-sulfite Caramel Color carries a positive ionic charge. The carbohydrate raw material is heated in the presence of both sulfite and ammonium compounds. The resulting Caramel Color carries a negative.
During the manufacturing process for Caramel Color, the carbohydrates polymerize with the reactants to form color bodies. The color components are virtually unabsorbed in the gastrointestinal tract and are not biologically available. The remaining caloric value of Caramel Colors can be attributed to unreacted sugars that remain after manufacture. The results have always been PCR Negative, indicating that they do not contain any genetic material.
Caramel Color is produced under high temperature, high pressure, and generally under acidic conditions. If any DNA was present in the starting carbohydrate, it would be degraded and hydrolyzed due to the processing conditions. European Union EU regulations do not take into account that there is no GE material in the highly-refined corn syrup used for Caramel Color E production.

Download our Absence of Allergen Statement pdf. Sulfiting agents used for stabilization are readily determined by both digestive and non-digestive methods.
The acid and heat used in this method break down digest the polymers releasing the sulfite. The FDA requires the labeling of sulfite on finished products ready for consumer use. The labeling requirement is only for finished products that contain 10 ppm of sulfite or more as defined by 21 CFR Caramel Color is not a finished product; it is an intermediary ingredient.
The usage level of Caramel Color must be taken into account to determine the possible final amount of sulfite in a finished product. Download our Sulfite Statement pdf.
Caramel Color undergoes strict laboratory testing to assure product quality. The three main laboratory tests to standardize a production lot of liquid Caramel Color are:. How is Caramel Color Colour made? Are Caramel Colors Colours the same as caramels? Are Caramel Colors Colours safe? Do Caramel Colors Colours provide clean label benefits?
