Ok guys and gals, I don't post here very often, so hopefully I won't sound too stupid.
I would like to extract the scent of garlic. I know that ruptured garlic tissue releases an enzyme that turns alliin to in to allicin, which is the
main component in the smell of garlic.
I have been contemplating a solvent extraction, using ethanol and a non-polar solvent...however I have also been looking into steam distillation since
I have all of the equipment to do so. I am worried about the details of the steam distillation because it seems like a more specific amount of detail
about allicin is needed in order to perform a steam extraction.
Which method would you consider the easiest for the purity and efficiency that you get out of it, and if steam distillation is the answer then could
anybody provide some insight or guidance as far as what details I need to know and and problems that may arise during the process?
Thanks in advance guys and gals,

Alliin is reactive. If extracted under gentle conditions like supercritical CO2
or anhydrous EtOH <0C, it won't keep for long once up to RT. OTOH, you
won't get it at all using steam or RT solvent extractions.

Drizzle whole garlic head with crude oleic acid triglyceride and sprinkle with granulated NaCl. Place in the oven at 177C for one hour. During that
hour, shit yourself over the mouthwatering aroma wafting from your oven. When complete, extract cloves from their husks and spread on buttered toast,
a good crusty French bread.
I suppose you could go ahead and extract it from the mush, but why? It's sooo goddamned delicious to eat

I'm mainly going for the scent of garlic more than anything, I love garlic a lot...tis the shit. Anyway I'm mainly doing it to prove a point to a
friend. not_important i will take a look at that attachment later today I'm looking forward to it...If i have questions I will be sure to post them
here
Thanks guys and gals,

u wanna extract the essential oil "aroma of garlic"
the best is steam distillation
or you can use cold pressing techniques
or infusion

Here are some tips for you. Freeze-drying. The freeze-drying of fresh garlic cloves is a method of flash evaporation at low temperature in a partial
vacuum. This method results in virtually no changes in chemical composition, and the resulting product is often used for culinary purposes. Low
Temperature Drying. This process involves drying sliced fresh cloves at temperatures <50°C for 3–4 d. Some allicin is formed due to the slicing
process. Distillation. Steam-distilled garlic contains principally allyl sulfides. Allicin is volatile and may be lost or converted to the allyl
sulfide degradation compounds. . Maceration in Oil. Chopped garlic is homogenized and slowly extracted (maceration) in soybean or another vegetable
oil.

Garlic seems to be pretty heat sensitive. Raw Garlic is hot and spicy. Take a few cloves of such garlic, and microwave it for approximately 60
seconds. The product will still be sort of garlic-y, but it will be soft, spreadable, and sweet.
