I think you misunderstood my post... in terms of artificial meat flavors and aromas.. think broth made with artificial chicken flavor and roasted vegetables vs a clarified broth made with out of roasted chicken bones and vegetables the two are pretty much identical for their odor and flavor. Smell them, have a sip of either and most people wont know the difference. Texture when eating has a big impact on perceived flavors and aromas too... which is what the rest of my post is about.
In terms of "meat substitute" products on the market for most of them the problem is texture and composition related. You can good ones like BBQ "soy riblet patties" which are pretty much identical in both flavor and texture to the cheapo MRE BBQ or McRib pork patties. Textured soy protein can be cooked and modified in a way that when seasoned is identical to the taco-bell ground beef filling. Make a slurry out of some soy-protein and an appropriately modified glutenous binder and some other textural modifiers with the chicken flavor blended in when breaded and fried will be identical to a chicken nugget. Or things like Asian style fishballs for soup.. can make very close proxies out of soy.
Most of the ready made "meat substitutes" are not really made all that well.. they are made to be "just good enough" to make a sale and keep selling. Things like Boca burgers and such being an invention of the 70s and 80s... food technology has come a long way since then.
As i said, processed foods to a degree are easily imitable.. larger meat cuts are not... may even be impossible to make a passable "steak" out of vegetable products. However, if you want it done right.. for now you have to make things out of scratch.
As for specific products.. I wouldn't know.. I don't shop by brands or specific ready made items rather mostly just bulk raw ingredients. Most ready made substitutes on the market right now are pretty awful. I get things like the big boxes of soy protein from amazon they seem to be very similar across the board though I tend to stick with Bobs Redmills and modify the product as needed at home. Great for cheap lean protein I can add to recipes to cut or supplement the meats.
