The chemistry of the Sunflower dye found in McCormick’s Color from Nature food dyes is explored in this post. This is the last in a three-part series in which several experiments and demonstrations that can be done with Color from Nature food dyes are described.
The American Chemical Society will celebrate Earth Day on April 22, 2017. This year's theme is Chemistry Feeds Our World. I have gathered some resources related to food and cooking from ChemEd X in honor of the theme. I have also included links to other resources.
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.
The chemistry of the Sky Blue dye found in McCormick's Color From Nature food colors is explored. This is part one of a three-part series in which the chemistry of McCormick's Color From Nature food colors is presented.
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.
In this Activity, students determine how many calories are released per gram when marshmallows and cashews burn and then compare the quantity of energy available from carbohydrates versus fats. Students burn the food items beneath a metal soft drink can containing water and measure the resulting change in temperature of the water.
In this Activity, students make slurries of breakfast cereal and water and use a magnetic wand to collect elemental iron filings that are present in some cereals. They determine the mass of iron collected and then calculate the "recommended daily allowance" (RDA) in each cereal. An extension uses qualitative tests to confirm that the material collected is actually iron.
