Sugar Science 101: Why is Sugar Important in Food Industry?

Image
With the increasing awareness among consumers about nutrition and healthy diet, a lot of people have started to see sugar as a devil, but if you ask me, I’ll say it is like an angel in disguise. If I randomly ask you about  what is the role of sugar in food , it is highly probable that you’ll say sugar makes food taste sweet. While sugar is primarily known as a sweetener, you cannot put it in a box.  Sugar is like an Indian movie star; it is versatile. For those of you who are not familiar with Indian movies or actors, I would tell you that the actors in India are not just actors; they are dancers, entrepreneurs, marketers and sometimes singers too. Similarly, sugar is a multi-talented ingredient in the realm of food. Here are a few of the other talents sugar has. It can balance flavours. Aside from increasing sweetness, sugar is also used to enhance, lessen or balance the flavour of ingredients naturally present in food. It contributes to the flavour profile by inte...

Kulfi Science: How Maillard reaction gives Kulfi its light brown colour?

The reaction that makes Kulfi a unique flavourful feast Every year during summers, I, like my mother, and her mother before her, used to wait for the Kulfiwala (Kulfi Seller) to arrive in our street in the evening and the moment we heard him shouting his arrival, we would step out of our home to greet him and buy kulfis to treat our sweet tooth. There’s no denying its power to tempt and make people fall in love with it. For those of you who are not familiar with this term, ‘kulfi’ is a popular Indian frozen dessert made from simple ingredients such as milk, table sugar and cardamom seeds ( elaichi) . You can also add nuts (and other ingredients) to the recipe.   But have you ever wondered why traditional Kulfi, which is made from milk that is white in colour, is light brown or cream in colour? And why does kulfi tastes so much better than milk? The most common method to make kulfi is a batch cooking process.   In this process, you heat the milk up to the boiling point (...

Fat Facts: Why Fats and Oils make our food so much better?

Image
Some people think that fat is a black sheep in the family of foods, while for others it is the golden goose. It all depends on what and how much you know about them. What are Fats and Oils?   In scientific parlance, fats are referred to as triglycerides, a.k.a esters of three fatty acid units attached to a molecule of glycerol. Did too many scientific terms confuse you? Let’s look at this another way. There’s a human named Wand - made from long chains of carbon, hydrogen and oxygen molecules. Wand is an alcoholic, but a very picky one. Once Wand is near his choice of alcohol- the sweet tasting alcohol called glycerol- the strong affinity unites them and together they become fat. Why are fats and oils so essential to cooking? Excellent carriers of flavours If you are an Indian or cook Indian food, you may have heard of the terms ‘Tadka’ (also sometimes spelt as ‘Tarka’) and ‘Chhaunk’. It is a process where oil is heated in a pan and then, spices are added (ac...

The Magic of Melting Ice Cream: Why different ice creams melt at different rates?

Image
Ice cream is one of the most popular, loved frozen treats. It is easily available and affordable. I have never met anyone who has never tasted ice cream. But have you bought different brands and types of ice creams and kept it at room temperature just to observe how much time it takes for them to melt. If you have done this, you would have noticed that not all of them melt at the same speed. Some will completely melt within a few minutes while others may take longer. So what makes ice cream melt and why not all of them melt within the same time? Here's what you need to know. Ice cream is usually made by mixing the milk fat, sugar (or sweetener), stabilizer and emulsifier. This mix is then pasteurized, homogenized, aged and frozen. During this whole process, water and fat molecules in the mix are brought together with the help of protein molecules, ice-crystals are formed, and air molecules get incorporated. In the end, ice-cream is a frozen foam that consists of air dispersed...

An Introduction to Wheat Gluten: the Glue that holds your bread together

Image
In December 2017, a video went viral on the social media platforms, spreading rumours that there is plastic present in Aashirvaad Atta. As a result of it, a lot of people started experimenting at home by adding water to wheat flour and were convinced that their dough is stretchy because the flour they bought has plastic in it. To   put all the doubts and fears to rest, in March 2018, the manufacturing company of Aashirvaad Atta- ITC - had to release a statement explaining how there’s no plastic in the flour, that it is just elastic protein- known as ‘gluten’. Wheat flour is a mix of a lot of molecules, from complex chains of carbohydrates to vitamins and minerals. But when it comes to bread baking, 'gluten' is the component bakers mostly rely on.  What is gluten? Gluten (a word derived from the Latin word ‘glue’) is the Fevicol of the food world. It is the thing that holds your roti, breakfast cereals, pasta and bio-plastics together. It is not present in flour b...

Discover the Science of Chocolate Flavour

Image
What makes chocolate so chocolaty? Chocolate. We all love it. Well most of us do. I am sure most of you have a specific brand of chocolate that you like to eat. But have you ever wondered what exactly is responsible for creating that unique sensory experience? Chocolate and cocoa products have a complex flavour. There are more than 600 volatile components in such products. Type and amount of these compounds and the way these compounds are made to react during the manufacturing process specify the flavour of the end products.   Today, I’m writing about the 4 main factors that lead to the development of different chocolaty flavours. 1.    The Birth Place and Genetic Origin of Cocoa - Cocoa is the main ingredient that influences the flavour in the final products. But not all cocoa beans are alike. Their genetics and geographical origin influence the final flavour in cocoa and cocoa products. Since the chemical composition of each variety of cocoa bean varies, eac...
