Actually, lactic acid encompasses a vast array of species of bacteria. It is used in food production such as yogurt and sauerkraut, fermented foods, etc. It lowers the pH of the food/beverage thus preventing growth of other bacteria. It does occur naturally as a byproduct of strenuous muscle activity, however it is commonly created for industrial use by fermentation of corn.

Vinegar works as a better preservative than salt because its acetic acid kills bacteria rather than just dehydrating as salt does. Not saying that salt is a bad preservative just that it doesn't eliminate as much bacteria as vinegar does.
Vinegar would be the best preservative. You can also use a little bit of salt or even lemon as preservative. Sugar syrup can also be used as a preservative if you want your sauce to be sweet.
The acidic nature of vinegar prevents bacterial growth.
The ratio of food preservative to vinegar in pickles can vary depending on the recipe used. Generally, a common ratio is about 1:3, meaning 1 part food preservative to 3 parts vinegar. However, it's important to follow a specific pickle recipe to ensure the proper balance of flavors and preservation.
Vinegar is acidic in nature, which is the reason for it being so sour.
Yes, acetic acid, commonly found in vinegar, can be used as a preservative due to its antimicrobial properties. It helps inhibit the growth of bacteria and molds, extending the shelf life of food products. However, it is not as effective as some other preservatives and may impart a strong flavor to the preserved food.
Vinegar acts as a preservative because there are not that many microorganisms that can live in it. It's a waste product of certain kinds of bacteria, but even they have problems once the concentration gets high enough... it's sort of like humans trying to live in a sewage pond.
to revent it from rancidity Usually as a flavouring or preservative. e.g. Pickled Onions are preserved in vinegar (an acid) the vinegar also adds flavour to the onions.
The answer depends in part on your application. Also, 'best' in what sense? Formaldehyde is a very effective preservative for biological specimens, but is not suitable as a food preservative if you intend to eat the food, as it is quite toxic. Copper compounds are excellent wood preservatives, but are also quite toxic. If you are looking for a non toxic food preservative, try salt or vinegar!
Salt is the best preservative among vinegar, salt, garlic, and sugar as it draws out moisture and inhibits the growth of bacteria, yeast, and mold. Sugar can also be an effective preservative by creating an environment where microorganisms cannot grow, but salt is more commonly used for preserving foods.
