Why Doesn’t Banana Candy Taste Like Banana?
TLDRThe video script delves into the quest to identify the source of the artificial banana flavor found in Laffy Taffy and whether real bananas possess a similar taste. It reveals that isoamyl acetate, a single molecule, is responsible for this distinct flavor, which is also present in actual bananas. The script discusses the Gros Michel banana variety, which some believe closely resembles the taste and smell of banana Laffy Taffy. The video also explores the history of artificial banana flavor, which predates the commonality of bananas in American markets. Through a series of taste tests and chemical analyses, the script investigates the isoamyl acetate content in various banana varieties, including the Gros Michel and the Cavendish, the latter being the current standard in grocery stores. The findings suggest that while both varieties contain isoamyl acetate, the Gros Michel does not have a significantly higher amount than the Cavendish. The script concludes by acknowledging the complexity and unexpected nature of scientific inquiry, particularly when dealing with chemically complex samples like those from living cells.

Q & A
What is the primary molecule responsible for the artificial banana flavor in Laffy Taffy?
-Isoamyl acetate is the primary molecule responsible for the artificial banana flavor in Laffy Taffy.
Why don't actual bananas taste like banana Laffy Taffy, despite containing isoamyl acetate?
-Actual bananas don't taste like banana Laffy Taffy because they contain many more smelly compounds than just isoamyl acetate, which can mask the specific flavor associated with the candy.
Which banana variety is believed to taste and smell a lot like a banana Laffy Taffy?
-The Gros Michel variety is believed by some to taste and smell a lot like a banana Laffy Taffy.
What happened to the Gros Michel banana variety in the early 1900s?
-The Gros Michel banana variety was nearly wiped out due to a fungal plague in the early 1900s.
How did the artificial banana flavor come into existence before the common availability of bananas in the American marketplace?
-The artificial banana flavor was developed by scientists in the 1800s who were experimenting with carbon-based molecules in the lab, and it came before the widespread presence of Gros Michel or other bananas in American markets.
How is isoamyl acetate synthesized in a lab?
-Isoamyl acetate is synthesized by mixing isoamyl alcohol with acetic acid, adding a catalyst, and heating the mixture.
What did the taste test of Gros Michel bananas reveal about their similarity to Cavendish bananas?
-The taste test revealed that the Gros Michel bananas were very similar to Cavendish bananas in taste, with a notably different aftertaste that was very sweet.
What method was used to extract the smelly compounds from the bananas for chemical analysis?
-The method used was to crush bananas in pure alcohol, let it steep for a while, and then drain the solid parts out, creating a 'banana essence'.
Which chemical analysis technique was used to identify isoamyl acetate in the banana essence samples?
-Gas chromatography and mass spectrometry (GCMS) were used to identify isoamyl acetate in the banana essence samples.
What were the findings regarding the isoamyl acetate content in Gros Michel and Cavendish bananas?
-The findings showed that both Gros Michel and Cavendish bananas had significant amounts of isoamyl acetate, with no significant difference between the two varieties.
Why might the presence of isoamyl acetate not be detectable in some banana varieties?
-The presence of isoamyl acetate might be masked or not detectable in some banana varieties due to the presence of other compounds that can change or mask the banana fragrance.
What additional information is available for those interested in further analysis of the differences between Gros Michel and Cavendish bananas?
-Preliminary results and additional data, including information about other compounds like furfuryl alcohol, are available through a link provided in the video description for those interested in further analysis.

🍌 The Quest for the Most 'Bananay' Banana
The video begins with a reflection on the artificial banana flavor found in Laffy Taffy and a curiosity about the actual chemical compounds that give bananas their distinct taste. The host aims to understand why regular bananas don't taste like the candy and introduces isoamyl acetate as the molecule responsible for the artificial flavor. It's revealed that this compound is also present in actual bananas, but the multitude of other compounds in them dilute the 'banana Laffy Taffy' taste. The Gros Michel banana variety is highlighted as one that some believe to be reminiscent of the candy's flavor. The video also discusses the historical shift from the Gros Michel to the Cavendish banana as the standard due to a fungal plague. The host explores the origins of artificial banana flavor, which surprisingly predates the common availability of bananas in the U.S., and notes that many Americans might have tasted the artificial flavor before trying a real banana. The segment ends with a taste test of Gros Michel bananas, with mixed opinions on whether they taste more like banana Laffy Taffy than common Cavendish bananas.
🧪 Chemical Analysis of Banana Varieties
The second paragraph delves into the scientific process of extracting and analyzing the chemical compounds of different banana varieties to determine their isoamyl acetate content. The host describes a method for creating a 'banana essence' using alcohol to extract the compounds from the bananas. These essences are then sent for analysis using gas chromatography and mass spectrometry (GCMS) by Dr. Curtis Pulliam. The process separates and identifies the molecules, including isoamyl acetate, which is the focus of the study. The results show that the Gros Michel and Cavendish bananas have the highest levels of isoamyl acetate, contradicting the initial hypothesis that Gros Michel would have more. The team ponders why the taste test didn't align with the chemical analysis, suggesting that other compounds might be masking the banana Laffy Taffy flavor. Interestingly, many banana varieties tested had no detectable isoamyl acetate, complicating the understanding of what defines the 'banana flavor.' The video concludes with an invitation for further chemical research into the differences between the Gros Michel and Cavendish bananas and a teaser for a new PBS show about disaster preparedness.
