The chemistry of the Berry dye found in McCormick's Color From Nature food colors is explored. This is part two of a three-part series in which the chemistry of McCormick's Color From Nature food colors is presented.
Food chemistry is an interesting and fun class for students. Read the article for some suggestions about resources along with an outline of a unit developed around water in cooking.

It is the holiday season, and here in Colorado, it is finally starting to feel like winter with a storm predicted for this afternoon!
To squash any misconceptions, I would like to say first and foremost I am not a great cook. My husband graciously does most of the cooking in our house. However, as a chemist, I am fascinated by the complex reactions involved in everyday life. Pair this curiosity with the requirement to teach an elective, and the Chemistry of Cooking elective was born.
In Chemical Mystery #7, a can of Coca-Cola was observed to sink in one container of water and yet float in another! This trick made use of the fact that the density of water changes with temperature. See the video below.

In this Activity, students investigate flavorings by making artificial "cooked apples" from a mixture of crackers, sugar, cream of tartar, and water, as is done for the filling in recipes for Mock Apple Pie. This Activity focuses on consumer chemistry, and can be used to introduce natural and artificial flavors or lab experiments that make esters.
