Salt and sugar act as preservatives by drawing out moisture through osmosis, which inhibits the growth of bacteria, yeast, and mold that cause spoilage.
Salt. It has been used for centuries to inhibit spoilage of food.
To prevent food spoilage, methods like refrigeration, vacuum sealing, drying, canning, using preservatives, oxygen absorbers, and proper packaging are commonly used.

To balance out the taste of salt which is a cheap preservative
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.
Most bacteria, which cause food spoilage, cannot tolerate the high salinity. The salt draws out moisture, causing them to die.
The addition of salt or sugar reduces the water that is available so that spoilage organisms won't grow.

Potassium bisulfate is a salt compound that is a combination of potassium and bisulfate ions. It is commonly used as a food preservative and in the production of wine to inhibit the growth of spoilage microorganisms.
A natural preservative is a substance from plants or minerals that prevents spoilage and extends shelf life without synthetic chemicals. Food preservation techniques are important for keeping our food safe and fresh for longer or throughout their shelf life. There are many effective methods including the use of oxygen absorbers and other traditional methods like Salting, canning and drying. Oxygen absorbers help absorb and retain excess oxygen from the surroundings, and effectively help to prevent any spoilage in the food products and keep nutrients intact.
Salt is not only a seasoning, but it's also a natural preservative. Sugar can be sweet or savory, it all depends on what you mix it with.
