What critical difference in application dictates the choice between Sodium Benzoate and Potassium Sorbate for food scientists?
Answer
The pH threshold analysis
The performance ceiling dictated by acidity is the critical difference; Sodium Benzoate is highly effective below pH 4.5, while Potassium Sorbate maintains power up to around pH 6.5, influencing selection based on the product's acidity level.
