This will cause your fried product to absorb more oil and product undesirable colors and flavors in your food. It is recommended too only salt after frying.
What breaks up cooking oil?

What happens to the food during deep frying?
Frying is a process of immersing food in hot oil with a contact among oil, air, and food at a high temperature of 150 °C to 190 °C. The simultaneous heat and mass transfer of oil, food, and air during deep‐fat frying produces the desirable and unique quality of fried foods.
Why are free fatty acids bad for deep frying?
Free fatty acids and their oxidized compounds produce off‐flavor and make the oil less acceptable for deep‐fat frying. Di‐ and monoacylglycerols, glycerol, and free fatty acids accelerate the further hydrolysis reaction of oil ( Frega and others 1999 ).
What happens when you add salt to deep fryer oil?
Salt: Excess salt may be added especially during rush hours resulting in foam formation through soap formation and direct oil breakdown. Bad or rancid oil is caused when a morsel of food is cooked in hot deep fat, the water on the surface and all foods contain moisture reacts with the fat and it hydrolyzes it, therefore freeing all the fatty acids.
