What is the minimum acidity level required in vinegar when pickling foods?

• A. 2.5%
• B. 5%
• C. 10%
• D. 12%

Answer: (B)

The minimum acidity level required in vinegar for pickling foods is 5%. This level of acidity is essential because it helps to create an environment that is hostile to harmful bacteria, thereby ensuring food safety during the preservation process. The acetic acid in vinegar serves as a preservative, and achieving this acidity level is critical for effectively inhibiting the growth of pathogens such as Clostridium botulinum, which can cause botulism, a severe foodborne illness. Using vinegar with less than 5% acidity may not provide adequate preservation and could lead to spoilage or safety issues. Conversely, vinegar with higher acidity levels can also be used, but it is crucial that the minimum specified acidity of 5% is met to ensure the safety and quality of the pickled products.
