Why Do Ripe Fruits Smell Bad?
601789
Ripening is a process in fruit that causes them to become more edible. In general, fruits become sweeter, less acidic, less green, and softer as they ripen.\n\nStages of a plant's life are influenced by hormones. An important plant hormone involved with ripening is the chemical ethylene, a gas created by plants from the amino acid methionine. Ethylene causes increased levels of certain enzymes in fruit, which include:\n\n    * Amylase, which breaks down starch to produce simple sugars, and\n    * Pectin's, which breaks down pectin, a substance that keeps fruit hard.\n\nOther enzymes break down the lime pigment chlorophyll, which is replaced by blue, yellow, or red pigments.\n\nHormone levels in fruit are often connected to pollination. If too few seeds in a multifaceted fruit are formed (by fertilisation of the ovules), the flesh of the fruit may not develop in some areas, and ripening will be retarded or prevented. Fruit growers increasingly monitor seed ratios in developing and/or mature fruit and adjust pollination management accordingly.\n\nMany fruits are picked prior to full ripening because ripened fruits do not ship well. For example, bananas are picked when green and artificially ripened after shipment by gassing them with ethylene. It is also possible to speed ripening at home by placing unripe fruit in a bag with an apple, which will give off natural ethylene gas.

Some peoples' natural pH levels cause them to have unpleasant odors coming from their nether-region. It's kind of like how some peoples' BO smells worse that others--it's a scent they naturally produce.

That's sounds sooooo disgusting. Don't get me wrong, i like my pina coladas once in a while,but it's never this early in the day.Just thinking about it makes my tummy shudder.

The sugar content goes up as the fruit ripens.

Dude.. that used to happen to me all the time when I would work food service. I would come home and smell all sorts of funky. Now I smell like chocolate or vanilla or sometimes even strawberry. I work in an ice cream factory... but smelling like nasty milk is not very appealing either.

It depends, are you talking an alive person, or dead? If you're talking alive, then all we smell like is blood, kind of like iron and meat, except for the stomach, colon and bowels. They really aren't pleasant to smell. If you have an infection, that part of you will smell bad, it's really pretty nasty. \n\nIf you are talking dead, then yes, you stink. The smell comes from bacteria created to feed off your dead tissue, decomposition. That really smells horrible!! There is nothing worse then the smell of a decomposing body. As another person stated, when someone dies they will evacuate everything in their bowels and bladder. So that smell adds to the smell of decay. \n\nWhen I used to do medical research on bodies, the smell was horrible, but it's because of the chemicals they use to preserve the body. There were some days it took everything in me not to have to leave the room. I learned that the best way around it is a little bit of vikks vapor rub under your nose.. you don't smell anything after that, and it leaves your lip nice and tingly!!

It's true, what you eat affects how it smells, but what you eat also affects skin, urine, sweat, and breath odors.  Limiting extremely pungent = smelly, foods will help. Food like garlic, onions, curry powder, etc.  However garlic is good for you and peppers like jalepenos cause some cancer cells to self destruct. I realize you may not want to hear this from a female but the truth is if who ever is in the position to be smelling/tasting your sperm, they probably like you enough that it doesn't matter.....or if it is the taste that gets to them then have the person use mouth wash or brush their tongue before hand.  It desensitizes the taste buds so it is hard to taste anything.

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

Fruit's good as long as it's one fruit. If it's Strawberry scent, that's cool. If it's Peach Melon Lemonberry Sugar Pie, no. D:

Scientists are still trying to decipher exactly what is the mechanism by which we taste and smell.  But this we do know: vapors from the substance in question enter the nose and interact with receptor sites there that are keyed to specific responses in the brain.  The combination of the receptor sites that are activated by the vapor generate a signal that the brain interprets as "smell"/"odor"/"aroma" (take your pick).\n\nThink of the various smells you exerience each day -- pears have an ester known as n-amyl acetate that generates that characteristic smell.  Iso-amyl acetate smells like bananas.  \n\nAnd then there are the fouls smelling compounds -- usually containing sulfur -- such as hydrogen sulfide (rotten eggs), or  methanethiol (or methyl mercaptan) -- which is used to generate the smell in natural gas (which is otherwise odorless), or butanethiol -- skunk spray!\n\nAmines typically have a fishy, musty odor.  Fatty acids tend to have a rancid smell.\n\nEach of the chemicals I have mentioned has a variety of chemical structures, and some similarities: the thiols all have a -SH group in the molecule somewhere, which interacts with receptors in our noses to send a signal to the brain of YUCK!! NASTY!!  Most esters have a pleasant, fruity smell -- there, the characteristic group is R-C(O)O-R'.  Primary amines have the R-NH2 structure, secondary amines replace 2 hydrogens with organic groups, and tertiary amines replace all three hydrogens with organic groups, but they all have that nitrogen in there. \n\nI hope that helps.

Unripe mango is sour in taste because of the presence of oxalic, citric, malic and succinic acids.

Certain foods can cause odors to be secreted from the body within sweat or other bodily fluids (ie: garlic, onions). \n\nBad breath can be caused by not doing a thourough cleaning of the tongue. Also, alchohol, including mouthwashes containing it, make bad breath worse.\n\nIt may not be the person themselves causing the odor. It could be the clothes they are wearing. Certain odors from the surrounding air/environment can embed themselves in clothes (ie: cigarette/cigar smoke odors). Also, if they are not washing there clothes in hot enough water bactera can still be present on them. We all know bacteria thrives in moist, dark areas so if the bacteria is present for example in the armpit of a shirt, if the individual wearing it perspires, this moisture combined with the darkness of the armpit area can cause the bacteria to thrive and produce an odor. \n\nWhen we think of "B.O." we think of the stink being screted by the individual themselves when in fact sweat dosn't stink at all. It is the bacteria that causes the smell.\n\nA natural way to rid the body of odor would be to wash frequently to prevent bacteria growth and to avoid foods with strong flavours and odors.

From the fishy smell? lol

Food you eat can also cause I change in smell. Asparagus and Brocolli are notorious. Excessive red meats can do it too.

i think those avocados were TOO ripe. same with mangoes and other fruits, when they are too ripe, they cause this burning or "scratchy" sensation in the tongue -- very unpleasant. sometimes it's even itchy.

Yes this means you are in ketoacidosis.  Your blood sugar has ran so high your body is compensating for it.  The fruity odor is a definitive sign of ketoacidosis.\n\nSeek medical attention today!
