Oil and Vinegar Do Mix…When You Have an Emulsifier

Science Fair Project Idea

Scientific Method

In this cooking and food science fair project, you will explore the role of proteins as emulsifying agents. Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsions include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to aid the smooth incorporation of fat into the dough and to keep the baked goods tender. Natural… Read more

Perfect Plating: Which Food Presentation Technique is Best?

Science Fair Project Idea

Scientific Method

Did you know that people eat with their eyes as well as with their mouths? Food presentation—also called plating techniques or garnishing—makes food appear more appetizing. Checking out how the food looks is the cook's last task and the diner's first. Food that is well-presented is beautiful, colorful, and captivating. Not only does it make the diner really want to eat, but good presentation also allows the diner to identify the food ingredients, their quality, and the technique… Read more

Save Those Spoiling Strawberries!

Science Fair Project Idea

Scientific Method

Fresh strawberries and summer just go together. Walking through the local farmers' market on a warm day, the bright, red strawberries call out to you, beckoning you to buy them and take them home. The next day, as you get ready to savor the delicious berries, you notice that yesterday's juicy, red strawberries are now covered in...eewwww, mold! In this cooking and food science fair project, you will investigate thermotherapy and whether this technique can preserve strawberries and prevent mold… Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more

Stand Up! Investigate the Effect of Different Bowls on Whipped Egg Whites

Science Fair Project Idea

Scientific Method

Whipped egg whites are used in many sweet and savory recipes. They are used to add air into cake batters, meringues, and soufflés. Egg whites, also known as albumin are 15 percent protein dissolved into water. When egg whites are beaten or whipped, the protein chains unravel. This is called denaturation. The process of whipping egg whites adds air to the mixture, in addition to denaturing the proteins. The denatured proteins create bonds with each other and trap air bubbles within… Read more

The Art & Science of Making Yummy Yogurt

Science Fair Project Idea

Scientific Method

Yogurt is a very versatile dairy product. It's yummy eaten straight from the container, it is good for your digestive system, and it can be used in several ways for cooking. There is historical evidence that yogurt-making developed 4,500 years ago! Humans depended on yogurt-making as a way to preserve milk. Yogurt is the result of bacterial fermentation of milk. In fermentation, the bacteria consume the milk sugar, lactose, and produce lactic acid. The end-product is a thick, creamy, and tangy… Read more

The Effect of Roasting on Color, Flavor, and Texture of Peanut Butter

Science Fair Project Idea

Scientific Method

Peanut butter is a popular ingredient in sandwiches, cookies, and many other common foods. In this cooking and food science fair project, you will roast peanuts in the oven at 350 degrees for 20, 30, and 40 minutes to produce variable levels of color and flavor. Roasting not only adds complex flavors to the peanuts, but it also destroys enzymes that produce off-flavors. Each lot of roasted peanuts will be used to make a batch of peanut butter. You will evaluate each batch of peanut butter for… Read more

The Pasta Puzzle: How Much Water is Required to Cook Pasta?

Science Fair Project Idea

Scientific Method

A plate of spaghetti, meatballs, and marinara sauce is a delicious and comforting meal. It's also an inexpensive meal, because it only costs about $12 to feed a family of four. And it's easy to make when you're on the go and need to eat a quick, but healthy dinner. Just boil a big pot of water, throw in your favorite pasta, cook for 11 minutes, drain, and top with meatballs and warm marinara sauce. Quick and cheap! But sometimes it feels like forever when you are waiting for water to boil,… Read more

The Sweet Beginnings of Caramelization

Science Fair Project Idea

Scientific Method

Caramelization is the name of the cooking process that occurs as sugar is heated and the molecules begin to break apart. But what happens to the sugar as it breaks apart? And what do the physical changes mean for the flavor of the sugar? Using the Internet or cookbooks, read up on the chemistry of caramelization, then head to the kitchen with an adult to caramelize your own batch of sugar. With an adult's help, dissolve 1 1/3 cups of sugar in 2/3 cup of water. Heat the mixture in a pan over… Read more

Top Crops: Finding Hidden Grasses and Beans in Processed Foods

Science Fair Project Idea

Scientific Method

It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more
