However, soy flour provided the highest moisture content at the end of frying due to its hard and crisp crust serving as a barrier to prevent moisture loss.
Moisture retention of soy flour added batter may be due to its higher water binding capacity
Due to its high water binding capacity, soy flour added batter can control moisture loss and so the oil uptake during frying. Higher viscosity and so the pick-up of soy flour added batter was also effective in controlling oil uptake.
