Web Search
• Choose starting search terms.• Evaluate results. If wrong or too vague, refine
search terms.• Skim and survey the resulting pages. • Compare to find similar ideas and terms.• Create a new search based on new
information.• Repeat, now taking detailed notes.

Research
pH• This is a way to measure
how acidic something is.• Low pH (<7) is more acidic.
pH and Food safety• Very acidic solutions can kill
bacteria (pH<4.6)• Using acids is called
pickling.
Food Safety• Microorganisms growing on
or in food can make it unsafe.
• Food safety relies on eliminating microorganisms or slowing their growth rate.
• Keeping food for long term storage in a safe way is preservation.

pH and Food Safety
• What – acids can make foods safe for preservation. Solutions with low pH are acidic.
• How - kill and/or injure microorganisms, especially below pH 4.6.
• Why – Cultures with a history of pickling, and/or areas where refrigeration and canning are not available or undesirable.
• When – When there is too much to preserve efficiently with other methods.
• Who – Traditionalists, or people in poverty.• Where – Poor areas, or areas with a tradition of preserving
foods.
