i've tasted acetic, malic, citric, phosphoric, and ascorbic acid solutions side by side in a few different concentrations, and there are noticeable differences between them.
it helped give me insight about which acids to use in different recipes (not just sauce making). it's worth trying imo.
there are many papers worth reading on the subject, but it's also something you should try out yourself.
regrettably, i have never tried lactic acid on its own. it's worth testing out! compare with some other common acids though to find what you like.

While lacto fermentation undoubtedly produces things other than lactic acid, I'm wondering how many of them are improving the taste of the sauce? As a homebrewer, I do everything I can to control my fermentation in such a way that the yeast do not produce any undesirable "off flavors." All I really need the yeast for is to create the alcohol. While there are some styles of beer that do have qualities that are derived directly from certain fermentation specifics, most do not. For most beers, you do everything you can to control it in such a way that you absolutely minimize all of the other "complexities" that contribute unwanted flavor.
i strongly disagree with that assessment. why not just add storebought grain alcohol to your wort and call it a day? surely that would be less work than beermaking.
i've never tried a beer where non-alcohol fermentation products were not absolutely central to the flavor.

So, I guess I really am just looking for that "bite." I realize that adding the lactic acid will not replace the complexities that a fermentation would bring. My goal is just that with the hot sauces that I've made so far, I cannot seem to replicate the same level/taste of acidity that I find in hot sauces that have "aged peppers" as an ingredient. I was assuming that "aged" meant fermented. While these sauces do not have lactic acid listed an ingredient, if it is a fermented sauce, I have to assume there is a fair amount of lactic acid making into their final product and that is the extra acidic quality that I cannot seem to replicate. I'm not tasting a drastic difference in complexity, those sauces just seem to have more of an acid bite that I have yet to create using strictly vinegar and or a combination of vinegar/lime juice.
My goal is to find that extra bite. I know that I can achieve it through fermentation; I'm wondering if I could skip the fermentation and just add the lactic acid? Probably could experiment with Acetic acid as well, for that matter. Was just curious if anyone else had tried this before I jump in and start experimenting. My real concern is trying to figure out how much to use. As a hot sauce making noob, I welcome any critique in my thinking here.
there's all kinds of sauces.
if you don't want fermented, then don't ferment. most sauces i've tried were not fermented.
and yes, for flavor, food safety, and shelf life, acids are added all the time -- even to fermented sauces! imho acetic acid (vinegar) is the most common.
how much to use?

pH levels-
The pH scale is the level of acidity or alkalinity in a product. Without getting all scientific here, basically, the lower the pH number, the more acidic the sauce is, and the safer the sauce is. Neutral pH is 7.0. Levels above 7.0 are alkaline, levels below 7.0 are acidic. Target levels for pH in foods intended to be shelf stable are 4.6 for licensed food processors. It's my recommendation for home sauce makers to shoot for 4.0 minimum and below to allow for a margin of error in all the aspects of sauce making.
