Overview

A project about cheese and the science behind it.

Problem

The problem is that we feel that cheese is misunderstood, some people think that its just putting milk in a place and adding bacteria and calling it a snack, cheese has a lot of different nutrients and it's science is fantastic. However, it is more complicated then that.

Method

Our method is that we study how cheese is really made. Also, we studied the science behind it. Cheese has a lot of interesting factors like it's discovery, cheese's discovery was completely accidental when people put milk in animal stomachs.

Research

Our research talks about the discovery, the science and the process.

People discovered cheese by placing milk into animal bladders, letting the natural enzymes coagulate the milk, turning it into cheese.

Certain types of bacteria make certain types of cheese. Propionibacterium makes swiss cheese while Penicillium freudenreichii makes blue cheese. To make it taste better you use rennet from cows. While it coagulates, it separates it turning it into cheese curds and whey.

Cheese has less lactose than milk, edible longer, and lots of lots of flavors. It contains more nutrients. Even though it has more saturated fat, it does not increase cardiovascular diseases by a lot.

It does contain more calories than milk. Also, it has more sodium, making it slightly more unhealthy.

Data

According to our research, most people say that cheese is healthier despite having some negative elements to it cheese is high in calories but has less lactose. Cheese no matter the type is delicious and a enjoyable snack for anyone. The process of cheese is interesting as it uses a liquid then turning it into cheese!

Conclusion

We have concluded that cheese is a easy tasty snack to make at home with some ingredients and that we know that to make cheese you need some certain types of bacteria which is funny as some bacterias will make you sick.
