Food science is a broad industry that is necessary in the modern world. As the demand for specific recipes and food items, such as low fat, low carbohydrate, low sugar grows, the food science industry continues to expand.

We’ll break down food science for you, including what it is, why food science is important, and how to start a career in the industry.

Food scientists work to understand the chemical makeup of the freshest ingredients.


What is Food Science?

Food science is the broad-ranging field of science used to better understand and solve real-world problems surrounding the complex food system. The entire industry of food science includes biochemistry, chemistry, nutrition, microbiology, and even engineering. At its core, food science studies the general makeup of food. Scientists need to understand basic nutrition concepts, such as carbohydrates, fats, protein, and water to better understand how they react with one another when they’re processed or preserved.

In food science, researchers work to research and analyse multiple methods of processing and preservation. This includes drying, freezing, pasteurizing, and canning, just to name a few. In doing so, scientists are better able to produce quality control methods. Microbiology and safety aspects of food need to be understood, as well. Eventually, the food products developed will be put on the market so the average grocery shopper can consume them.

The food science industry includes studying agriculture to feed the planet more safely and sustainably.

It’s clear scientists work to understand processing and preservation. Researchers in the food science industry also study topics like food additives, flavour chemistry, product development, food engineering, and food packaging. The end goal depends on the job in question. For some food scientists, the desired outcome is learning how to create a frozen meal that tastes delicious and can be warmed up and enjoyed at a moment’s notice. For others, it’s researching and analysing the perfect container for food before it goes to market.

Ultimately, food science integrates all of these broad-based concepts such as microbiology, chemistry, nutrition, and engineering and focuses it specifically on food.
