Food caramels: a review
Caramel, defined as coloring agent and as an antioxidant, is being used in several kinds of food products. It has been classified into 4 classes to satisfy the requirement of several food and beverage systems. The variation in its consistency owing to its basic content of milk solids, sugars, and fat has been studied.
Several methods have been found to estimate the amount of color provided by caramel in food products. Various formulations have been cited for the production of caramel by eradicating the frequent areas of problems during its processing. Caramel has been used as a synthetic colorant replacer in the baking and beverage industries. Researchers have aimed to ascertain the contribution to the antioxidant activity of some caramel-containing soft drinks.
This paper is an overview of the classification, physicochemical nature, formulations, coloring properties, antioxidant properties, and toxicity of caramel in different food systems. Caramel is a complex blend of fat globules in varying size groupings surrounded by a high-concentration sugar solution in which milk solids-not-fat are dispersed or dissolved.
Heating enhances the browning reaction and regulates the finished product moisture content de Man The greatest single factor affecting the texture and chew is the amount of moisture left in the caramel.
Color stability, and flavor are also considered important characteristics in applications. Besides these, recently caramel has also been highlighted as beneficial in non-enzymatic browning inhibition. A strong type of caramelization with yet another flavor is obtained by alkaline treatment; for example, by the reaction of sodium bicarbonate with boiling syrup at about The action of ammonia on certain reducing sugars also produces a caramel color.
The polymeric material from plain caramel is generated from the condensation reactions of the aldehydes and ketones formed by heating the sugar with bases or acids. Ammonia caramel is formed in a Maillard-type reaction where carbonyl compounds react with amino groups or ammonia. Sulfite caramel is also a Maillard-type polymer and the information on that caramel composition is of practical importance. Caramel colors have been used for a long time and in a wide variety of food products so that consumers tend to think of them as a single substance, when in reality they are a family of similar materials with slightly different properties.
Each type of caramel color has specific functional properties that ensure compatibility with a product and eliminate undesirable effects, such as haze, flocculation, and separation.
Caramel colors are dark brown to black liquids or solids having an odor of burnt sugar and a pleasant, somewhat bitter taste. They are totally miscible with water and contain colloidal aggregates that account for most of their coloring properties and characteristic behavior toward acids, electrolytes, and tannins.
Guelfi noted that American caramel is a distinctive class of confectionery, differentiated from European caramel by lighter color, opacity, and, generally, a predominance of dairy flavor over darker caramelized flavor.
Myers and Howell overviewed the chemical characterization and specifications of the 4 classes of caramel color, the historical development and the methods of manufacture.
There are 4 distinct types of caramel color to satisfy the requirements of different food and beverage systems JECFA ; Codex :.
Caramel Color IV known as sulfite-ammonia, soft drink caramel, or acid-proof caramel. Depending on their isoelectric points pIs caramels may be roughly divided into positive pI 5.
The pI determines the possibility of application of caramels. Other important properties are pH, aqueous solubility should be completely soluble , specific gravity usually 1. Its flavor has 2 organoleptic properties consisting of 2 components: taste arising from the acidity modifiable and a taste contribution attributed to the nature of the caramel no-modifiable Tomasik The differentiation was done based on the nature of the compounds generated by pyrolysis.
According to international standards, color intensity is defined as the absorbance of a 0. To express a parameter on a color equivalent basis, the parameter is determined for the caramel color and is expressed in terms of a product having a color intensity of 0.
The Eighth Amendment to the Colors Directive of the European Union makes it clear that these 4 classes of caramel color are intended for coloring and are to be distinguished from and do not correspond to the sugary aromatic products obtained from heating sugar and used for flavoring foods and drinks known as burnt or caramelized sugars. Caramel may be used for coloring ingested food or for topically applied drugs. High pressure liquid chromatoraphy analysis revealed unique profiles within each class and distinct differences between classes.
The data indicated that each of the 4 classes can be considered as separate and that, throughout each class, the samples characterized constitute a homologous series of mixtures in terms of chemical composition Licht et al. Monosaccharide D-fructose, D-glucose, anhydrosugars , disaccharide glucobioses , and pseudodisaccharide di-D-fructose dianhydrides contents of D-fructose, D-glucose, and sucrose caramels were determined by gas—liquid chromatography—mass spectrometry GLC—MS as their trimethylsilyl TMS or TMS—oxime derivatives Ratsimba et al.
Caramel is polymeric in its character. In , the French chemist M. Gelis authored the first known published technical study of caramel color Gelis The presence of aldehydes of the furan series in caramel accounts for its antioxidant properties Zenkevich et al. Ammonia caramels additionally contain melanoidin which is much darker in color than the 3 other components mentioned above. Hence, ammonia caramels are the most colored Tomasik Vtllalon et al.
Zenkevich et al. Carbohydrate and fat contents in caramel largely dictate the structural and rheological properties of products; hence their constitution is essential to be analyzed. Maurice noted that caramel covers a wide range of textures and physical characteristics, from a soft, free-flowing liquid, suitable for an ice cream or dessert sauce, to a more viscous center for molded chocolate units, or from a firm, chewy texture, suitable for cut-and-wrap units, to hard English toffee.
Caramel as fat droplets within a matrix of sugars was imaged by the use of pulsed-force atomic force microscopy AFM and scanning thermal microscopy Morton et al. Caramel is physically a glass consisting of viscous syrup with milk solids dissolved or dispersed in it and with fat emulsified into it.
The viscosity of the syrup binding the whole structure together depends on many variable factors, particularly water content and anions present in the reaction, such as phosphate, carbonate, acetate, sulfite and so on which influence the reaction path. It has been found that the physical and physicochemical properties of food polymers in the glassy state are much different from those in the rubbery state. Many researchers have demonstrated that the glass transition has a strong impact on food texture Rogers et al.
Unexplained variations in the rheological properties of caramel are an ongoing problem in the confectionery industry. A number of factors responsible for these variations have been suggested, such as protein concentration seasonal variations in the raw milk Weckel and Steinke , forewarming of milk, and salt balance. Milk proteins play a major role in modifying the textural properties of caramel. Cooking temperature of the caramel mix, and processing conditions used for sweetened condensed whole milk SCWM , including time and temperature of the fore-warming treatment, were the factors having the greatest effect on the textural properties of caramel Tonucci and von Elbe Molecular and mechanical relaxation properties of caramel systems as a function of temperature and composition using nuclear magnetic resonance NMR and dynamic mechanical analysis DMA were studied by Chung et al.
Corn syrup, the major carbohydrate in the original recipe, was replaced by polydextrose to different extents. The glass transition temperature Tg of the caramel systems was estimated using NMR and DMA techniques; it increased with increasing polydextrose content.
Cold flow, one of the most important rheological characteristics was retarded in the higher- polydextrose caramel system, coincident with the decrease in proton mobility of the caramel system. Dynamic shear results revealed viscous behavior for caramel samples. Differential scanning calorimetry DSC was employed to examine the thermal transition of caramels. A shift in glass transition temperature Tg was noticed during thermal scanning cooling and warming of the caramel samples.
Melting and crystallization temperatures were varied among the caramels. Testing temperature and variation in compositions resulted in differences in rheological parameters and melting and crystallization temperatures of the caramels. Steiner et al.
The molecular mechanisms for sensory texture and stickiness of caramel can be used following such correlations with the help of equations of correlation coefficient. Pons et al. The process includes continuous trapping on adsorbent when heating, followed by a thermal desorption and overall analysis.
Fifty-seven compounds were detected by this technique and also by solvent extraction and vapor analysis during cooking. Some unexpected intermediate volatile molecules were noted which can play an important role in the formation of the flavoring compounds. Controlled heat treatment of carbohydrates produces caramel. The carbohydrate raw materials used are the monomers- glucose and fructose or polymers thereof such as glucose syrups, sucrose or invert sugars, and dextrose.
For promoting the process of caramelization, food-grade acids, alkalis, and salts may be used in amounts consistent with Good Manufacturing Practices GMP and subjected to the following stipulations.
For Class I caramel colors, ammonium and sulfite compounds cannot be used as reactants, for Class II caramel colors sulfite compounds must be used and ammonium compounds cannot be used as reactants, ammonium compounds must be used and sulfite compounds cannot be used as reactants for Class III caramel colors whereas both ammonium and sulfite compounds must be used as reactants for Class IV caramel colors.
The ammonium compounds used are hydroxides, carbonates, bicarbonates, phosphates, sulfates, sulfites, and bisulfites, and the sulfite compounds are sulfurous acid and sulfites and bisulfites of potassium, sodium, and ammonium. Sulfuric acid and citric acid, and sodium, potassium, and calcium hydroxides are compounds that can be used for all 4 types of caramel color Kamuf et al. There are endless numbers of caramel formulations.
Dairy products such as milk, milk protein, lactose, or butterfat formulates the final quality of caramel Warnecke Next to chocolate, caramel is the confection which is used in more types of candy than any other. Its formulations and process conditions must be modified to suit quite a wide range of textures.
By far the most important ingredient in caramel is milk. It was noted by Chirafisi and Milashouris that milk protein is the major contributer to the texture, body, and flavor of caramel. A milk processor generally considers milk as composed of water, milk solids nonfat, and milk fat. These components vary by breed of cattle, feed, and climate. The amount of water in milk makes the product very perishable due to the high water activity.
The lactose in milk is a naturally occurring disaccharide sugar. When subjected to heat it contributes to the distinctive caramel color via the Maillard reaction by interaction with amino acids found in the protein. It is often used as a bulking agent as it does not provide much sweetness and can positively carry and enhance flavors.
Several studies have demonstrated that structural and physicochemical properties of proteins can have significant effects on the textural properties of food products Marshall and Harper ; De Wit ; Patel and Kilara Chirafisi and Milashouris patented a caramel formulation by the use of Umerie and Enebeli ascertained the feasibility of obtaining caramel from malted tubers of Cyperus esculentus.
Mudadi et al. When the mucilage, composed of galactose, glucose, arabinose, and rhamnose units, was heated, a brown color was formed. The presence of ammonium salts and pH had only a small effect on the development of color. Rittenberg focused on the problems occurring while manufacturing caramel. It is also desirable to determine the water and fat contents of caramel simultaneously in one single analytical step.
In the classic time domain NMR methods, the differentiation of water and fat was not sufficiently good as the differences in relaxation times of oils and fats are relatively small.

Low 4-methylimidazole (4-Mel) caramel color class IV production
Caramel is a candy created when sugar is heated to degrees Fahrenheit degrees Celsius. As sugar is heated slowly to this temperature, the molecules break down and form new compounds that have a deep, rich flavor and dark golden brown color. This process is known as " caramelization " and can be achieved with any variety of sugar. Toffee and butterscotch are similar to caramel but are made with brown sugar or molasses and have butter added, whereas caramel is made with white sugar. The two are also cooked to different candy-making stages. These stages refer to a specific temperature range when cooking sugar syrups and indicate how pliable or brittle the candy will be. Butterscotch is boiled to the soft crack stage. Toffee is heated further to the hard crack stage. The soft crack stage occurs at to F. During this stage, the sugar concentration of the syrup is 95 percent, which affects how pliable or brittle the candy will be.

It can be used as a flavoring in puddings and desserts , as a filling in bonbons , or as a topping for ice cream and custard. As the sugar heats, the molecules break down and re-form into compounds with a characteristic color and flavor. Ice creams sometimes are flavored with or contain swirls of caramel. The English word comes from French caramel , borrowed from Spanish caramelo 18th century , itself possibly from Portuguese caramel. Caramel sauce is made by mixing caramelized sugar with cream. Depending on the intended application, additional ingredients such as butter, fruit purees, liquors , or vanilla can be used.

Caramel is often eaten as little brown, sweet, buttery nuggets wrapped in cello-phane, but it is also delicious in candy bars and on top of fresh popcorn. The best caramels are sweet and just a bit chewy. Caramels can, in fact, have a variety of textures. Caramel manufacturers use the term "short" to characterize a caramel that is too soft perhaps too moist or "long" for a caramel that is quite chewy. Caramels are, in some ways, rather similar to other candies in that the basis for candy is generally sugar, com syrup, and water.

Caramel color or caramel coloring is a water-soluble food coloring. It is made by heat treatment of carbohydrates sugars , in general in the presence of acids , alkalis , or salts , in a process called caramelization. It is more fully oxidized than caramel candy , and has an odor of burnt sugar and a somewhat bitter taste. Its color ranges from pale yellow to amber to dark brown. Caramel color is one of the oldest and most widely used food colorings for enhancing naturally occurring colors, correcting natural variations in color, and replacing color that is lost to light degradation during food processing and storage.
