Abstract
If you browse through a candy cookbook, you might notice that many of the recipes call for corn syrup in addition to sugar. Both sugar and corn syrup are sweet, so why do you need corn syrup if you already have sugar? In candy making, corn syrup is known as an interfering agent. But what does this mean and how does it work? You can find out for yourself by making two batches of rock candy, one with corn syrup and one without. For example, you could alter the science project When Science is Sweet: Growing Rock Candy Crystals by replacing 1 tablespoon (tbsp) of water (in the sugar-water solution) with 1 tbsp of corn syrup in one of the batches of rock candy. (Make sure the batches are prepared the same in every other way.) Are there any differences between the two rock candy batches? Once you understand what an interfering agent is, you could try experimenting with other ingredients to see if they can act as interfering agents, too.Bibliography

Career Profile
There is a fraction of the world's population that doesn't have enough to eat or doesn't have access to food that is nutritionally rich. Food scientists or technologists work to find new sources of food that have the right nutrition levels and that are safe for human consumption. In fact, our nation's food supply depends on food scientists and technologists that test and develop foods that meet and exceed government food safety standards. If you are interested in combining biology, chemistry,…
Career Profile
Good taste, texture, quality, and safety are all very important in the food industry. Food science technicians test and catalog the physical and chemical properties of food to help ensure these aspects.
Career Profile
The role that the chemical technician plays is the backbone of every chemical, semiconductor, and pharmaceutical manufacturing operation. Chemical technicians conduct experiments, record data, and help to implement new processes and procedures in the laboratory. If you enjoy hands-on work, then you might be interested in the career of a chemical technician.
