What are the typical preservative concentrations in syrups?

Explanation:
Syrups need a preservative system because they are aqueous products that can support microbial growth. A common approach is to use a combination: benzoic acid or sodium benzoate around 0.2%, parabens around 0.1%, and alcohol around 15–20% to provide additional antimicrobial action and help dissolve flavors. This mix gives broad spectrum protection while keeping taste and safety in balance. The other options either use amounts that are too high or too low for typical syrup formulations, or propose no preservatives at all, which would increase the risk of contamination even though sugars can provide some preservation.
