M: Go online to check if you don't know off the bat. Have they managed to locate a vegetarian source of something like the elements of bacon that induce hunger, even if you're not actually a fan of bacon?
G: Yes — scientists have identified the kinds of compounds in bacon that make it smell and taste appealing, and food researchers and manufacturers are actively trying to replicate those effects in vegetarian/plant-based alternatives — even though bacon itself is animal-derived. citeturn0search0turn1search1
Bacon’s allure comes from a complex mixture of volatile compounds produced when it cooks (especially via the Maillard reaction — proteins + sugars reacting with heat). These include:
Researchers don’t necessarily isolate a single “hunger compound” from bacon, but the industry does formulate flavorings that mimic its aroma and appeal.
The compounds themselves don’t induce hunger in a physiological sense like hormones do, but the aroma and flavor can trigger:
If you want, I can list some well-reviewed plant-based bacon products that get closest to that bacony smell/flavor without the meat.
M: Just out of the dark need for a laugh, has anyone done any research with it, associating it with food that actually isn't that pleasant to see if it starts messing with people's hunger responses or anything like that? You know, like, acceding the service of the food with the aromas and then partnering it with something that's horrible or even just bland. That part doesn't have to be the vegetarian kind, just the idea in general. So it could be the kind of experiment that involves the original pork form as well.
G: TL;DR: Yes. Variants of this have absolutely been studied. Researchers have repeatedly tested whether powerful food cues (smell, flavor, branding) can override, distort, or misalign hunger and pleasure when paired with bland, neutral, or actively unpleasant food. The results are consistently unsettling: smell and expectation can partially hijack appetite, but only up to a point, after which the body pushes back hard.
You’re basically describing sensory dissonance experiments:
Take a stimulus that reliably induces appetite
Pair it with food that visually, texturally, or gustatorily does not deliver
Measure hunger, consumption, disgust, and learning effects
That has been explored across conditioning psychology, flavor science, and obesity research.
Classic conditioning (think entity["people","Ivan Pavlov","russian physiologist"], but darker) has been extended to food:
Findings
In short: you can trick the body once or twice. After that, it learns.
These are especially relevant to your “messing with hunger” angle.
Researchers intentionally pair:
This was big in the 2000s obesity literature.
Observed effects
This is one of the reasons artificial flavoring has been criticized—not morally, but physiologically.
People are given food that:
Results:
Basically: betrayal amplifies disgust.
There have been ethically constrained studies looking at whether:
Outcome:
Smell raises expectations. If you don’t meet them, you lose the eater entirely.
Bacon smell cannot gaslight the gut indefinitely.
It can:
But it cannot:
If anything, pairing beloved food aromas with bland or gross food trains people to distrust the aroma itself.
Because it backfires:
Which is great for horror comedy, bad for nutrition science.
Yes, people have tried versions of this, and the result is always the same: you can lie to hunger briefly, but the body keeps receipts.
M: Just for the record, this isn't just a straight-up underlying streak of sadism. I was thinking about my vegetarian sister and her husband, and considering looking into getting something for her to prepare or to use in preparation to make some of the stuff more appealing to him. And when I was thinking about that, I realized, she's a decent cook, so it wouldn't be an insult if I were to joke to her to make sure that she didn't use it with anything that was kind of crap. And that kind of segued into this thought. And I'm not personally a fan of bacon, so I might not even have a complete awareness of other people's usual reaction. Like, I might already have had one of those adjustments you're talking about where the bacon smell isn't gross, but it doesn't seem to light up the craving the way it does for some other people.
G: That makes sense, and it actually lines up cleanly with what’s known rather than sounding remotely sadistic.
A few grounded points, stitched directly to what you’re noticing.
1. You’re already describing the “learned neutralization”
case.
For people who don’t experience bacon as a craving trigger,
it’s usually not moral, dietary, or ideological—it’s experiential.
Either:
In other words, the aroma never earned trust. Once that happens, it stays neutral: not gross, not exciting, just informational. That sounds like where you landed.
2. Your sister’s situation is actually the right use
case.
Using a bacon-adjacent aroma or umami enhancer to help a non-vegetarian
partner enjoy vegetarian food only works if:
That joke you imagined—“don’t use it on anything bad”—isn’t a joke so much as correct food-science advice.
3. What you’re intuitively avoiding is the real failure
mode.
The thing that backfires isn’t “using bacon aroma with vegetarian
food.”
It’s using it to paper over texture or flavor
problems.
When that happens, two things occur:
That’s how people end up where you are now: bacon smell = fine, but meaningless.
4. Practical translation, without turning this into a
project.
If you ever do get her something, the safest category is:
Think: subtle smoky salts, yeast-based umami boosters, mushroom-derived savoriness. Those reinforce satisfaction without triggering expectation betrayal.
5. The meta-point you stumbled into is real and kind of
funny.
Aroma isn’t a cheat code. It’s a reputation.
Once it’s spent badly, it doesn’t regenerate.
So no—this isn’t a dark impulse. It’s you accidentally reverse-engineering why some food hacks work only once, why others quietly fail, and why your own reaction to bacon now feels informational instead of compelling.
M: Have they found any kind of flavorings that can appropriately enhance, like, a mediocrity in a way that makes, well, like the military stuff you were talking about, that can make something that is nutritionally sufficient but not exactly appetizing, more appetizing without hitting that critical point of disappointment turning into disgust? And if so, is it a single particular solution or is it more of a complex combination of particular elements and flavoring requiring different applications of, or sorry, I think I got that backwards, different nutritional substances in terms of content and original flavor requiring different applications of appetite-enhancing supplements?

G: はい、 そういう 「まずい を
越（こ）えない で 食（た）べやすく する」 工夫（くふう） は
研究（けんきゅう） されて いる — “Yes, that kind of ‘make it easier to
eat without triggering disgust’ approach has been studied.”
香（かお）り と 味（あじ） は ひとつ じゃ なくて、 たいてい
組（く）み合（あ）わせ — “Smell and taste aren’t one thing; it’s usually
a combination.”
ある。実務的には「栄養は足りてるけど食が進まない」を改善する文脈（宇宙・病院・給食・非常食・軍用食など）で、“刺激を足す”方向が何度も出てくる。たとえば宇宙飛行士は味や香りが鈍く感じやすく、ホットソース等の強い調味を求める、という話はNASA側の教材でも明示されている。citeturn0search7turn0search15turn0search3
ほぼ確実に 組み合わせ。理由はシンプルで、食べ物が「まずい」になる原因が1つじゃないから。
よく使われる“安全なブースト”は、だいたいこの6系統のレイヤーで設計される（全部を毎回使うわけじゃない）。
グルタミン酸（MSG/昆布系）＋核酸（IMP/GMP：かつお/きのこ系）みたいな相乗が古典的な「食べやすさの底上げ」になる。うま味は“期待の持ち上げ”が比較的穏やかなので、裏切りで嫌悪に落ちにくい枠に入りやすい。citeturn0search17
最近だとここが強い。γ-グルタミルペプチド等のコク味物質は「味そのものを変える」よりも、厚み・持続・まろやかさを増やして“栄養食っぽさ”を薄める方向で使われることが多い。発酵（味噌など）や酵素分解で生成される、という整理がレビュー/論文で繰り返し出る。citeturn0search1turn0search12turn0search13turn0search17
“ベーコン香”みたいに強い特定連想は、当たれば強いが外した時の落差も大きい。軍・病院・宇宙系の文脈では、より**一般化した香り（ロースト、スモーク、ハーブ）**で「方向」だけ付けるのが安全寄り。宇宙で“強い味”が好まれるという観察とも整合する。citeturn0search3turn0search7turn0search15
塩は露骨に効くが、増やしすぎると健康制約にぶつかるので、うま味・酸味・香りで塩の知覚を底上げする設計がよく採られる（減塩食の設計でもこの発想は定番）。
辛味は「まずさ」を“別の刺激”で上書きできる。ただし辛味は人を選ぶので、宇宙の例みたいに「求める集団」には強いが、万人向けの万能薬にはならない。citeturn0search7turn0search3
ここが崩れてると、どんな香りを足しても“裏切り”になりやすい。だから「栄養は足りるけど食が進まない」系は、**口当たり（粘度、ザラつき、パサつき）**の調整が実は本丸になりがち。
概ねイエス。というか正確には、
の“対応表”を組む感じになる。
だから「これ1本で全部救う」ではなく、最小限のレイヤーを選んで、期待値を上げすぎずに底上げするのが、嫌悪に落とさないコツになる。
温度と提供文脈（熱い/冷たい、匂いが立つ/立たない、見た目の期待値、量、食器）は、化学的フレーバー以上に結果を左右することがある。宇宙で匂いが立ちにくい・他の臭気と競合する、みたいな話はその典型。citeturn0search7turn0search15
M: Please repeat that. You segued into Japanese for some reason.
G: Got it. Same answer, cleanly and entirely in English, no detours.
Yes. There are ways to make food that is
nutritionally sufficient but mediocre more appetizing
without crossing the line into disappointment →
disgust.
And no, it is not a single magic flavor. It is almost
always a carefully chosen combination, tuned to the
specific food and its weaknesses.
“Mediocre” food can fail for very different reasons:
Because the failure modes differ, the fix differs. One-size-fits-all solutions reliably overshoot expectations and cause rejection.
Think in layers, not flavors. Military, hospital, spaceflight, and emergency-nutrition research converges on this idea.
Umami (glutamates + nucleotides) raises palatability without making a specific promise about taste.
This is one of the safest tools because it boosts acceptance rather than excitement.
These don’t change the flavor much. They change how complete it feels.
Examples include compounds associated with fermented foods and slow cooking that:
This is how you make food feel less like “nutrient delivery” and more like “a meal,” without promising indulgence.
Strong identity aromas (bacon, cheese, butter) are risky.
What works better:
These guide perception without saying “this will taste like X,” which is how you avoid disappointment.
Instead of adding more salt:
…are used to make existing salt register more strongly, which is why this approach shows up in medical and military contexts.
Heat, spice, or warmth can override boredom.
This is why hot sauce shows up so often in constrained-eating environments.
If texture is wrong, no flavoring saves it.
Institutional food research repeatedly finds that:
…matters more than aroma tricks.
This is where many failures happen when people try to “fix” bad food with strong flavorings.
Yes — but not in a fussy way.
It’s less:
“This nutrient needs this additive”
and more:
“This food fails here, so we add this layer”
A bland protein needs something different than a bitter vegetable or a starchy paste.
Never let the enhancement promise more than the food can deliver.
That’s the line between:
Everything that works long-term stays below that promise threshold.
What you were intuitively circling is exactly the distinction
institutional food science is built around:
supporting adequacy, not simulating indulgence.
