Candy making is not just an art; it's a science. Each candy represents a precise balance of ingredients and chemical reactions to create the perfect flavor, texture, and appearance.
Sugar, the Magical Ingredient
At the heart of candy-making is sugar. The type, quantity, and crystalline structure of sugar used significantly impact a candy's taste and texture.
The Role of Temperature
Candy-making is a temperature-sensitive process. The way sugar is heated and cooled can result in a variety of sweets, from hard candies to gooey caramels.
Candy makers manipulate sugar crystals to achieve the desired texture. Different crystal sizes and shapes create the familiar structures found in fudges, toffees, and brittles.
Acid-Base Reactions
Many candies rely on acid-base reactions for their unique flavors. Think of the effervescent sensation in sour candies, thanks to the reaction between acids and baking soda.
Emulsifiers like lecithin are used to blend ingredients that wouldn't naturally mix, creating the creamy textures in products like chocolate and fudge.
Maillard Reaction
This reaction between amino acids and reducing sugars is responsible for the browning of candy, such as in caramel.
Inversion
Inverting sugar (breaking down sucrose into glucose and fructose) is a fundamental process to prevent crystallization in candies like fondant and marshmallows.
Flavor Extracts and Oils
Chemical compounds in flavor extracts and essential oils give candies their unique tastes, from the zesty notes of citrus oils to the richness of vanilla extract.
Coloring Agents
Color plays a significant role in candy. Synthetic and natural food colorings are used to create vibrant and appealing hues.
Texture Modifiers
Texture is carefully adjusted using various modifiers, like gelatin in gummies and pectin in fruit candies.
The Delicate Balance
Candy makers are akin to culinary chemists, carefully orchestrating these chemical processes to ensure that every piece of candy is a delectable masterpiece.
At Ideal Candys, we celebrate the sweet science that goes into creating each candy. Our candy makers are not just artisans; they are chemists, transforming simple ingredients into extraordinary delights.
Stay tuned for more insights into the enchanting world of confectionery, where chemistry and creativity meld to create candies that captivate the senses. Until then, keep savoring the wonders of life, one sweet bite at a time.
The way sugar is heated and cooled can result in a variety of sweets, from hard candies
hard candies
A hard candy (American English), or boiled sweet (British English), is a sugar candy prepared from one or more sugar-based syrups that is heated to a temperature of 160 °C (320 °F) to make candy.
to gooey caramels. Candy makers manipulate sugar crystals to achieve the desired texture. Different crystal sizes and shapes create the familiar structures found in fudges, toffees, and brittles.
In general, candy is made by dissolving sugar into water to create a solution. Granulated sugar, the most common type used in candy-making, is sucrose, a disaccharide molecule made up of glucose and fructose. When you force these two molecules to break apart, a very tasty reaction occurs: caramelization.
A supersaturated solution is unstable—it contains more solute (in this case, sugar) than can stay in solution—so as the temperature decreases, the sugar comes out of the solution, forming crystals. The lower the temperature, the more molecules join the sugar crystals, and that is how rock candy is created.
Foods that stimulate the reward system in your brain, like sugar and other foods that spike your blood sugar, can lead to cravings. Foods that are hyperpalatable (those that are sweet, salty, creamy and easy to eat) can also trigger hormones that contribute to cravings—such as insulin, dopamine, ghrelin and leptin.
To make candy, sugar is first heated to a high temperature so that it melts . The scalding solution is then then cooled into a solution that is supersaturated. The supersaturation is considered unstable, forcing the sugar molecules to crystallize into a solid.
The technology of candy making is based on the science and art of altering sugar, the principal ingredient in candy, particularly to achieve special textural effects. Thisis accomplished primarily by controlling the state of crystallization of the sugar and the sugar– moisture ratio.
Interfering agents (e.g., cream of tartar, lemon juice, corn syrup, molasses, or vinegar) are added to sugar syrup mixtures to prevent the formation of large crystals.
Stress hormones play a big role in sugar cravings. Exercise is a proven stress reducer and a great way to calm sweet cravings. “Exercise will help decrease your ghrelin levels. It can also help you to be more tired, get to sleep and stay asleep a little bit longer, which also reduces cravings,” Czerwony explains.
Hydrogen bonds between sugar and nearby molecules help to determine the level of sweetness. Sugars are thought to owe their sweet taste to the particular pattern of bonds that atoms in sugar molecules form with receptor proteins in taste buds.
Several lines of evidence suggest that oxytocin may be specifically involved in regulating the intake of sweet-tasting carbohydrates, and this has been linked to actions of oxytocin in the nucleus accumbens, an important part of the reward circuitry of the brain 26, 27.
The secret behind candy making lies in the skill of manipulating the inherent size and shape of a sugar crystal — more formally known as sucrose. As the compound is heated to different temperatures, it will move through several candy stages until the desired effect is achieved.
Temperature control is critical when it comes to candy making, so having an accurate thermometer can make all the difference. While the common candy thermometer can measure temperatures up to about 160 °C, data loggers designed for commercial candy production can withstand higher temperatures.
Candy canes are created by boiling a mixture of water, sugar (sucrose), and corn starch to create a syrup, to which peppermint flavouring is added. Menthol is the chemical in peppermint that makes your mouth feel cold – it triggers cold-sensitive receptors.
Candy is made by dissolving sugar in water or milk to form a syrup, which is boiled until it reaches the desired concentration or starts to caramelize. The type of candy depends on the ingredients and how long the mixture is boiled. Candy comes in a wide variety of textures, from soft and chewy to hard and brittle.
The dyes used to make colored candy can be made up of several colors. These dyes are composed of different compounds that separate during chromatography. The water rising up the filter paper caused the compounds in the candy to spread out in a spectrum.
Caffeine 6, ascorbic acid and citric acid are also common candy ingredients. Citric acid gives candies like lemon drops their tart flavor. For more information about candy and its chemistry, see these resources: Britannica.
