Do pieces of food go into air to smell it?

Yes small molecules are drifting in the air and the olfactory nerves pick them up and the brain deciphers them.  Also as a side note, I believe it is 60 percent of taste is made up from what you smell.  That is why when you have a cold and can't smell food tastes so bland.

Human sense of smell is designed to identify things which are bad for you so you can keep away from them/not eat them/not smell them, in order to avoid disease.\n\nEveryone's gut contains bacteria - often a specific combination of bacteria that your own gut has built up for itself and finds useful in digesting food and fending off 'alien' bacteria.  \n\nEssentially this means that your nose is smelling someone else's gut bacteria and recognises them as alien and not good were you to ingest them for any reason. \n\nSo it's just your nose's way of telling you that these bacteria are bad and not to get too close - that's why some smells are 'bad' and some are not.

Some it doesnt smell, some it does depending on what you eat.\n\nhttp://sexuality.about.com/od/sexualhealthqanda/f/vaginaltaste.htm\n\nhttp://www.teenwire.com/ask/2004/as-20040209p735-smell.php

The odor of farts comes from small amounts of hydrogen sulfide gas and mercaptans in the mixture. These compounds contain sulfur. Nitrogen-rich compounds such as skatole and indole also add to the stench of farts. The more sulfur-rich your diet, the more sulfides and mercaptans will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts.

Are you asking - can you smell the smell you just smelled on your breath?????????\n\nInteresting thought.\n\nOMG!!!!!!!! I hope not, I sometimes have to use the toilet after my husband's been in there.......... and I'd hate to think that THAT was on my breath!!!

lmao, mr chili that's so funny.  The odor from flatulation (fart) is actually microscopic particles of feces along with body heat and gases. That is where the smell comes from. \n Once those particles are no longer airborne and fall to the ground the smell can no longer be detected, it's at your feet not up at nose level.\n\nDid you really poot in a box and seal it up? Ahhhh-haaa. LOL!!

poop isnt supposed to smell bad, really!!!  Its just a bad diet that causes the stench.  I am a vegetarian and my poop has no odor!

Most of the odour comes from molecules released by bacteria in the gut.  Some are facultative; they can live with or without oxygen.  Some of these release hydrogen disulfide (rotten egg gas.)\n\nOthers are anaerobes; they live only in the absence of oxygen.  Many of these release fatty acids and amines from the larger molecules they digest for food; fats, proteins, nucleic acid, etc.  Some fatty acids are very pungent; some smell like butter, or strong cheese, or dog faeces etc.\n\nThe anaerobes are even pungent if cultured in our laboratory!  When we are culturing from some samples, the stinky ones generally contain anaerobes.  A good sense of smell is very handy in Clinical Microbiology.\n\nYears ago, I read research (that was done in inbred mice strains) showing that the genes of the animal had an influence on the types of bacteria that remained in its gut.  They said this was part of the reason why different strains of mice could recognise close relatives by smell; genes resulted in smells.\n\nI think this explains why different people make different odours, though fed the same foods.

NO.  only after hours when the bacteria from the air grows in the wine,  when opening a bottle of wine it is best to let it 'breathe' to get the best flavor, breathing refers to 'off gasing' some of the fermentation gases.

The senses are connected.  When I inhale through my nose I can smell but can't taste.  When I exhale through my nose I can taste but can't smell.  Try it and see if it works the same for you.  Maybe I'm just weird.

Maybe it doesn't like the smell of what you're eating.

it's called the process of diffusion. as a smell spreads out its molecules use the air molecules to move away as gas molecules are so free. soon there is very little atoms of the fart smell left that it is unsmellable to the human nose although it's never truly gone!

Smell is based on the nose detecting the presence of molecules. If the smell is coming from an object there must be molecules coming from it. Whether that results in a loss of mass depends on how they are being released.\n\nIf the smell is from molecules on the surface of the object just floating free into the air, then yes it does lose that mass.\n\nIf the smell is due to molecules being released in a chemical reaction with the air or other surrounding substance, then the reaction *may* actually add to the object's net mass. Or it might not. It depends on the nature of the particular reaction.\n\nIn most cases I'd think it would be just molecules floating free so it would lose mass.

no because u smell ur shirt now. u r trying to smell ur shirt instead so u dont think about the other smell. the odor does go through.

From the fishy smell? lol

Depends on if you have food around you, or just the smell of food on you. It's not you they like, it's something they smell.
