Why do ripe fruits - especially when canned - smell bad?

Why do you think those answers were 'nonsense' and 'totally wrong'?
If most people thought ripe fruits smelled bad, there simply wouldn't
be a market for ripe fruits whatsoever, especially canned fruit. The
fact that both sell well should tell you that most people _don't_ find
them bad smelling.


You need to rephrase the question: "What chemicals are responsible for
making ripe fruit smell bad to me?" However, since we are not you, we
can't asnwer that. We don't know how or why your sense of smell is
different from most people.


What you need to do is to find an organic chemist who knows what fairly
volatile compounds are common in ripe fruit, eliminate those you listed
above (other than acids, many odoriferous organic compounds are acids, and
ripe fruits certainly contain acids), eliminate those in unripe fruit and
ripe apples, and ask for a sniff test of the remaining compounds.


If you are going to insist on dismissing what others have told you and
what should be obvious to you (there is something different about you),
and continue to claim ripe fruits smell bad rather than ripe fruits smell
bad to you, you're going to draw jokes and insults, or be dismissed as a
troll.

So are you really interested in an answer, or are you a troll? If
you really want an answer, nobody here can answer you, other than in an
organic chemistry lab.

A nice scientific explanation. If that does not satisfy him, nothing
will. Well done!

Now, care to expound on the fruit canning practices that turned your mom
off? I'm intrigued!

In Radium's defense, there's not a lot of information out there on
food constituents. Food companies, who have done the most research in
this area, are extremely secretive about their stuff, much like
cosmeticians and perfumers.

Natural odors are usually pretty complex. The odor and flavor of
apples was reconstituted by blending nine pure chemicals previously
identified by GC/MS and other methods.

Coffee flavor, on the other hand, has at least 640 constituents.
Changes in any one of them may dramatically affect the flavor.

I know this shit because I worked for 14 years in electronic
olfaction, ie, using chemical sensors to simulate the 150 or so odor
receptors in the human olfactory epithelium. What we call an 'odor' is
generally a combination of responses from many of these sensors.

Good book: Turin's 'The Secret of Scent', the memoir of a professional
perfumer. Some fascinating insights on odor and chemical structure.
For example, the odors of many chemicals are independent of the
stereoisomerism -- an observation that should stop most chemists in
their tracks. Possibly the best chemistry-related light read of 2006.
I gave copies to friends.

Sounds interesting. :-)

I have enough of a background in organic and biochemistry, I could
probably appreciate it.

Thanks for the recommend!

The only disease I am diagnosed with is Asperger's syndrome. I got a
brain scan 5 months ago, no anomalies -- such as tumors. In addition,
I am only 23, so you can take 'age' off the list. I've also taken
smell tests in my organic chemistry lab. I've takes organic chemistry
as a course in my college. Long list of chemicals I've gone through.
Still no answer to the stench of ripe fruits. In addition, none of the
chemicals I sniffed even remotely smell like ripe fruit.

My guess is the stink of ripe fruits is a result of a mixture of
different organic substances, excluding the following:

1. putricine

2. ethylene [sweet smell]

3. butyric acid [or any acid/acidic substance for that matter]

4. ethanol [sweet smell resembling most alcoholic beverages]

4. chemicals resulting from fungus

5. chemicals resulting from decomposition

Ever since I was born, I've perceived the smell of ripe fruits to be
bad. Nothing has changed in terms of that. If I ever had a brain
tumor, the signs would show, and there would be other neurological
symptoms as well -- such as paralysis, involuntary movements, impaired
vision/hearing, visual/auditory hallucinations, impaired balance,
dizziness, vertigo, memory loss, false memories, distortion of
existing memories, loss of awareness, decreased level of
consciousness, alteration in sense of time, dissociative states,
tinnitus, etc.

It is a severe personality disorder that explains why he won't listen to

To Those Who Care:

I would like to give you some information about my disability. The
reason I am posting this message is to help avoid any potential
misunderstandings [though it's probably too late].

I have been diagnosed with Asperger's Syndrome (AS). AS is a
neurological condition that causes significant impairment in social
interactions. People with AS see the world differently and this can
often bring them in conflict with conventional ways of thinking. They
have difficulty in reading body language, and interpreting subtle
cues. In my situation, I have significant difficulty with natural
conversation, reading social cues, and maintaining eye contact. This
can lead to a great deal of misunderstanding about my intent or my
behavior. For example, I may not always know what to say in social
situations, so I may look away or may not say anything. I also may not
always respond quickly when asked direct questions, but if given time
I am able express my ideas.

However, it's important to note that Asperger's does not affect the
sense of smell.

On Usenet, the text-equivalent of my disability is probably noticed. I
do apologize profusely, for any inconvenience it causes.

Thank you very much in advance for your understanding, cooperation,
and assistance.


Best Regards,

Radium
