Turning cotton balls into cotton candy

TL;DR

YouTuber attempts to turn cotton balls into edible cotton candy using a homemade process involving acid, sugar extraction, and caramelization.

Transcript

about two years ago i became convinced that there was a way to turn cotton balls into edible and hopefully tasty cotton candy at first this idea seemed a bit ridiculous but i knew that it should have been possible this is because cotton even though it doesn't seem like it at all is technically entirely sugar the only problem is that all this sugar ...

Key Insights

• ❓ Cotton is primarily composed of cellulose, which is a sugar.
• 🍳 Enzymes such as cellulase can break down cellulose into glucose.
• ❓ Sulfuric acid can dissolve cotton and enable sugar extraction through hydrolysis.
• 😑 Ion exchange resin can remove impurities from the sugar solution.
• 🍬 Caramelizing the sugar is essential for creating cotton candy-like properties.
• 🍬 The homemade process yields edible cotton candy, albeit with certain imperfections.
• 🍬 The process requires iterations and adjustments to improve the quality of the cotton candy.

Questions & Answers

Q: How does cotton contain sugar?

Cotton is made up of cellulose, which is a complex sugar called glucose trapped within a structure called cellulose.

Q: Why did the YouTuber choose to use enzymes initially?

The YouTuber had previous success using enzymes in another project and believed it could break down the cotton into sugar.

Q: What challenges did the YouTuber face when sourcing the enzyme?

The YouTuber struggled to find a pure enzyme without additional sugars and encountered issues with customs when ordering from Alibaba.

Q: Why did the initial attempts at making cotton candy fail?

The YouTuber speculates that the caramelization process wasn't sufficient, resulting in a sugar with a lower melting point than regular cotton candy.

Q: How did the YouTuber overcome impurities in the sugar solution?

The YouTuber used ion exchange resin to remove charged impurities and later used activated charcoal to improve color and taste.

Q: Why did the cotton candy have a short lifespan?

The cotton candy created with the homemade sugar had a tendency to quickly melt, likely due to variations in the sugar's composition and caramelization.

Summary & Key Takeaways

• The YouTuber experiments with using an enzyme, cellulase, to break down cotton balls into sugar but faces challenges with impurities in the enzyme.

• They later devise a new process using sulfuric acid to dissolve the cotton, followed by sugar extraction through hydrolysis and purification with ion exchange resin.

• The resulting sugar is then caramelized and used in a cotton candy machine with mixed success, yielding edible but imperfect cotton candy.
