Title StatementThe feasibility of using Allium cepa L., Allium sativum, and Durio zibethinus as sources of odor for malodorants by James Enil Bulatao, Joseph Steven Esteban and Dan Emmanel Sison
Physical Description19
Summary, Etc.The study is about using extracts from Allium cepa L., Allium sativum and Durio zibethinus as cheap alternative sources of odor for malodorants. The odor was extracted by submerging 100 grams each of onion, garlic and durian in 400 ml of distilled, lukewarm water. A chamber with five separate compartments was constructed and its inner surface was layered with a plastic sheet, and then rags, so that the smell will not stick to the box and the rags would absorb the treatments once they are sprayed. A mouse was placed at the entry point near the treatment compartment and observations were made, after both the control and treatment were sprayed.  These were all repeated for 30 mice. This process was repeated, except that the mice were put at the entry point near the control compartment. Results prove that the onion and durian treatments were more effective than the onion treatment. The extracts were also tested on humans. Thirty individuals of the PSHS freshman population were randomly selected to do an evaluation of the odor of the extracts and rank their odor in scale from 1 to 10. The freshmen were selected because they have spent the least time in PSHS, therefore, having the least amount of time to develop any bias towards the group. Results proved that the strength of pungency of the extracts in increasing order is garlic:onion:durian. The conclusion for the study is that among the 3, the onion would be the best source of odor for a malodorant
