Hamburger (McDonald's)

For many people, hamburgers instantly recall memories of McDonald's and fast food. But have you ever stopped to think about the science behind creating one of these classic burgers? From the planting of the grain used to create the bun, to the 350 degree cooking oil where the patty is fried, to the packaging that enables it to reach your dinner plate, the production of a hamburger is a complex, multi-stage process requiring significant knowledge in biology, chemistry and engineering.

In this blog post, we'll detail the science behind a McDonald's hamburger and explain how it travels to a dinner plate.

Creating a Burger Bun

Before the burger can be made, the first step involves creating the bun. Firstly, the wheat used to make the bun must be grown; this involves a process called sowing which sees the wheat seeds scattered on the ground and plowed into the soil. Plant nutrients such as nitrogen, potassium and phosphate are added to the soil to aid growth, while cultivators work the ground to make sure the seeds receive the right amount of water, light and air.

Once the wheat has been grown, it is harvested and processed. This begins with the cleaning of the wheat grain, which sees the grains being stirred in huge vats to remove stones and other contaminants. The grains are then heated, cooled and hulled before going through a machining process to ground the grain into flour. From here, the dough is mixed to achieve just the right consistency, before being left to rise and proof. This is done by adding yeast and sugar, and then allowing the mixture to sit in a warm area until it has doubled in size.

Once the dough has been proofed, the next step involves shaping and baking the buns in an industrial oven. This oven is heated to around 500 degrees Fahrenheit and takes just a few minutes to bake the buns, resulting in a golden finished product.

Creating a Burger Patty

The next stage in creating a McDonald’s hamburger is making the patty. Firstly, the meat used to make the patty is usually a combination of different cuts of beef, which is then ground and ground together. The patty is then mixed with seasonings and fillers to achieve just the right flavours and texture. This mixture then goes through a pressing machine to form even patties, which are then frozen for transport. Once it reaches the restaurant, the patties are thawed before being cooked.

Cooking a Burger Patty

Once the patties are ready for cooking, they are placed in a 350 degree cooking oil for about five minutes, making sure the patty cooks through and is evenly browned. The hot oil sears the meat, locking in all the flavours, while also helping to create a crumbly texture. The patty is then removed from the hot oil and placed on a bun before being assemble into the classic hamburger.

Packaging, Storage and Delivery

Once the burgers have been assembled, they need to be packaged in order to ensure they are safe to eat when they reach the consumer. This packaging is usually made from paper or recyclable substances, and is designed to keep the product fresh whilst being transported. The burgers are then stored in climate-controlled containers to prevent spoilage and maintain their freshness.

Once the burgers have been packaged and stored, the most important step is delivery. This involves using a reliable process, such as refrigerated deliveries, so that the burgers remain fresh and safe until they reach the consumer. Once the burgers arrive at their destination, they are checked for quality, then heated and served to the consumer.

Conclusion

As can be seen, creating a McDonald's hamburger is a complex and scientific process, involving numerous stages and professionals in the fields of biology, chemistry and engineering. From the planting of the wheat grain and the processing of the dough, to the frying of the patty and the packaging that ensures it reaches the consumer in perfect condition, each step requires knowledge and understanding of how each element interacts with the other and how it travels from production to the dinner plate.

After reading this blog post, you should have a better understanding of the science that goes into creating a hamburger – from the growing of the grain, to the processing of the meat, the baking and frying of the patty, and the packaging that ensures it remains safe to eat, the production of a hamburger is a complex and multifaceted process which requires knowledge in multiple fields, and is vital to the production of all types of burgers today.”
