How long does pectin keep in the pantry, fridge and freezer?

How do you keep pectin safe to eat?

• These times assume the fridge is at 40°F or colder and the freezer at 0°F.
• Freezer times are for best quality. Food kept frozen at 0°F stays safe indefinitely; it just loses flavor and texture over time.
• Perishable food shouldn't sit at room temperature for more than 2 hours (1 hour above 90°F).
• Smell and looks don't tell you about the bacteria that make people sick, so go by the time, not by a sniff test.

• Thawing food safelyDefrosting frozen food in a way that keeps it out of the temperature range where bacteria grow.
• Storing produce so it lastsKnowing what goes in the fridge, what stays on the counter, and what to keep apart so fruits and vegetables last longer.
• Blanching vegetables for the freezerBriefly boiling vegetables, chilling them in ice water, and freezing them flat so they keep color and flavor for months.
