While sorbic acid is effective, it is not without its limitations. It is more effective in low pH environments, meaning its efficacy diminishes in foods that are acidic.

As a result, research into natural preservatives has gained momentum, yet sorbic acid remains a staple due to its well-established benefits and safety profile.
