In fact, not nearly all food flavors can be used for vaping. There are two criteria for them:
- the flavor has to withstand high temperatures and not chemically react in unpredictable ways;
- it must be safe for respiratory organs and mucous membranes.
The flavors most commonly used in vaping are nature identical. This has to do with the fact that natural flavors are fussy, spoil more quickly and behave unpredictably when in liquids (for example, they can leave residue on the coil). In turn, fully artificial flavors can have an unnatural taste. However, in practice all types of flavors are used, depending on the situation.
What are the ingredients? Manufacturers generally don’t disclose the composition of their liquids: it’s a closely kept trade secret. Nevertheless, we will tell you about several of the main components that are used in most popular flavors.
Most confectionery flavors contain acetylpyrazine. It gives the liquid an aroma of fresh pastry and a pleasant texture. Natural acetylpyrazine is found in sesame, cocoa beans and almonds, as well as in pork and beef.
Vanilla notes in confectionery liquids are provided by ordinary vanillin. There’s probably no point in describing its properties and usage. Vanillin can either be natural or synthesized from guaiacol and lignin. There’s also ethylvanillin: it’s synthesized from the same components, but its aroma is three times stronger.
Vanilla can be used to show the difference between types of flavors. Vanilla is a natural flavor, it is obtained from vanilla pods. Vanillin is a nature identical flavor: the composition is the same, but is derived from different components. And ethylvanillin is an artificial flavor. It’s much more tasty and cheaper in production, but differs in composition.
All other spice flavors are usually recreated on the basis of natural spices — those are cinnamon, ginger and sometimes cloves.
Some confectionery flavors contain diacetyl — a substance with a tender creamy taste. It gets added to many flavors like ice cream, cake etc. In nature diacetyl is found in coffee, chicory and grape juice.
For some time diacetyl caused controversy related to its harm to the human body, but at some point everyone agreed that the minuscule amount of it in most liquids doesn’t pose a threat to health. Nevertheless, in order to appease the public, manufacturers are gradually abandoning diacetyl in favor of its analogues.
