Sorbates include calcium/sodium/potassium salt of Sorbic acid and inhibit yeast and mold but they may be less effective on bacteria.

Sodium/Calcium Propionate prevent growth of mold but they are not effective on yeast or bacteria

Sodium Benzoate is used in preservation of acidic foods to prevent food from molding and also in beverages like fruit juices and soft drinks.  

Citric acid is used as a food preservative and is a natural acid found in lemons, limes, plums, grapefruit, oranges. They are extracted by adding calcium oxide which results in calcium citrate.
