Bacteria enjoy foods that are neutral to slightly acidic.
They will not grow in highly acidic foods like lemons and vinegars, but will grow well in vegetables, meat and some slightly acidic fruits.
Hence strong acids can help prevent the growth of bacteria.
Answer:
Foods with a pH below 7.0 are acidic; a pH above 7.0 is alkaline. The lower the pH, the higher the acidity; the higher the pH, the lower the acidity. Bacteria grow best in an environment that is neutral or slightly acidic. Most bacterial growth is inhibited in very acidic conditions.
