The Sweet Taste and Our Taste Buds
Have you ever wondered why we are naturally drawn to sweet-tasting foods? Well, there's a scientific reason behind it! Our tongues have around 10,000 taste buds, and each one has unique receptors for sweetness. When we eat something sweet, neurotransmitters (Dopamine) are released in our brain, stimulating the pleasure centres and making us feel good. In response, our brains produce endocannabinoids, which increase our appetite. It's like our brain is telling us, "More please!"
The Evolutionary Basis
But why do we have this natural preference for sweetness? It might have an evolutionary basis. You see, lactose, a type of sugar found in milk, is easily broken down into glucose, which is our body's primary fuel source. In fact, around 40% of the calories in milk come from lactose. So, when infants consume sweet milk, it increases their chances of survival. That's pretty cool, right?
The History of Sweetness
Sweet foods have been a part of human history for a long time. Our ancestors have been cultivating and breeding sweet fruits and vegetables for thousands of years. They also used natural sweeteners like honey, fruit juices, sap from trees, and nectar from flowers to sweeten their food. The OldWorld's first significant sweetener, honey, was even produced by humans using bees as a tool. Over time, humans learned to gather, refine, or concentrate sweeteners like maltose, glucose, fructose, and sucrose. It's like we've always had a sweet tooth!
The Love for Sugar Cane
Our love for sweetness is so strong that we even started growing sugar cane! In the past, people would chew or suck on pieces of sugar cane to enjoy its sweet juice. However, sugar cane was difficult to preserve or store because it would quickly degrade and ferment. But humans found a way to overcome this challenge and turn sugar cane into a preservable sweetener. That's how table sugar became so popular!
Types of Sweeteners
Now, let's talk about sweeteners. There are different types of sweeteners that cause sweetness and have different chemical structures. Some examples include sugars, sugar derivatives, d-amino acids, and artificial sweeteners. They all make our food taste sweet, but they are not all the same.
The Rise of Table Sugar
For the past 500 years, table sugar, also known as sucrose, has been the most popular sweetener. Sucrose is made up of two smaller sugars, glucose, and fructose, which are chemically bonded together. During digestion, these sugars separate, and glucose enters our bloodstream to be used as energy. The liver metabolises fructose into glucose. So, when we eat sugar, our body knows how to break it down and use it!
The Impact of Sweeteners
Sweeteners not only affect the taste of our food but also its texture and other properties. For example, they can change the viscosity (how thick or thin a liquid is) and water activity of a food. These changes can affect how aroma compounds are released and distributed in our food. It's like a sweetener can change the whole experience of eating! Food additives play a crucial role in enhancing the sensory experience of our favorite treats. Sugar plays a crucial role in baking as well. It helps bind ingredients together, adds texture to the crust, and contributes to the caramelization process. Sugar also provides aroma, flavor, and physical properties to bakery products.
Gummy Candies: A Sweet Treat
Who doesn't love gummy candies? These sweet treats are made with different gelling agents like gelatin, starch, and pectin. But the most important ingredients in terms of quantity are the sweeteners, such as sucrose, glucose, and corn syrups. These sweeteners not only provide the necessary sweetness but also contribute to the overall mouthfeel and flavor profile of gummy candies.
So, the next time you enjoy something sweet, remember that there's a whole science behind it. Our taste buds, brain, and even our ancestors have played a role in our love for sweetness. It's a fascinating journey that has shaped our relationship with food!
