Bacteriology is the study of microscopic living things called bacteria. Scientists are learning more about how to promote the growth of good bacteria and fight bad ones to improve our health. Additionally, bacteria are used in various industries to produce useful compounds.

People in equador regions use spices in food preparation for thousands of generations. By using these spices, are they keeping themselves healthy by keeping their food "clean?" My objective is to find out if spices have the ability to kill food-spoilage microorganisms. And if they do, which spices are most effective and by how much?

Spices have been used in cooking for thousands of years, but do they have the power to keep food clean and healthy? This experiment will test the antibacterial properties of seven different spices to see if they can kill food-spoilage microorganisms.


Mother Knows Best: A Study of the Health Benefits of Spicy Cooking

Objectives/Goals:

People in equador regions use spices in food preparation for thousands of
generations. By using these
spices, are they keeping themselves healthy by keeping their food "clean?" My
objective is to find out if
spices have the ability to kill food-spoilage microorganisms. And if they do,
which spices are most
effective and by how much? This is what I plan to find out after I have
conducted my experiment.

Methods/Materials:

My experimental setup was designed to test volatile emission from the spices.
After obtaining agar dishes,
E. coli, and sterile swabs from CSUF, I carefully streaked E. coli on all of my
dishes. Then I turned them
upside down and I applied 1/4 tsp. of spice on the lid. I used all of the
following spices: cinnamon, garlic,
mustard, black pepper, coriander, lemon juice, and chilli powder. Then I left my
dish at 27 degrees
Celsius for 4 days. I had three replicates.

Results:

The results of my experiment show that not all of the seven spices used were
effective. Complete
Inhibition- coriander 100%. Partial Inhibition- mustard 83%, cinnamon 67%, lemon
juice 67%, black
pepper 17%, and garlic 17%. None- chilli powder 0%.

Conclusions/Discussion:

According to my results, spices do have antibacterial properties, but not all of
them. This is potentially
beneficial in tropical countries that have ineffective food storage methods.
