Separating salt from food completely is generally impossible without significantly altering the food itself. However, you can reduce the saltiness through several methods. The best approach depends on the type of food.
Methods to Reduce Saltiness in Food
-
Dilution: Adding more unsalted ingredients like water, potatoes, rice, or pasta increases the overall volume, thus diluting the salt concentration. This is effective for soups, stews, and sauces. [Source: Quora]
-
Absorption: Some ingredients can help absorb excess salt. Raw potato cubes added to a salty gravy or sauce can draw some salt out. Similarly, rice powder balls can be used. [Source: onmanorama.com]

Physical Removal (Limited Effectiveness): While you can't directly remove salt crystals, you can try to remove salty liquid. For instance, if a sauce is overly salty, you might carefully skim off some of the liquid from the surface. This only works if the salt is dissolved in the liquid, not if it is already bound within the food.

Chemical Methods (Advanced and Not Recommended for Home Use): More complex chemical processes could potentially separate the salt, but these are not practical or safe for home cooks. Examples mentioned in chemistry forums include atomization and vacuum separation, but these are highly specialized techniques. [Source: Chemistry Stack Exchange]
It's important to note that completely removing salt from food without impacting its composition or flavor is typically not feasible. The focus should be on reducing the perceived saltiness through the methods described above.
