Expiration & Storage Tips
When does penne pasta expire?
If left unopened, a packet of dry penne pasta can last up to two years past its 'best by' date, as long as it's stored in a cool, dry place. Once the pasta packet has been opened, it's best to use it within one year. Fresh, homemade penne pasta has a comparatively short shelf life and should be consumed within two to three days if stored in the refrigerator. Freezing fresh pasta can extend its shelf life up to two months.
How do you tell if penne pasta is bad?
To tell if penne pasta has gone bad, you would need to use your senses. For dry penne pasta, it's all about the appearance. If it has developed a muddy or dark hue, it's time to throw it out. Any signs of mold, bugs or an 'off' smell also indicate that the pasta is spoiled. Fresh penne pasta will change in color and texture when it starts to go bad. It will develop a slimy or sticky surface, mold, a sour smell or change color to grayish or greenish. If you notice any of these changes, it's best to throw it out.
Tips for storing penne pasta to extend shelf life
• Store dry penne pasta in a cool, dry place like a cupboard or pantry.
• Once opened, seal the leftover pasta in its original box or transfer it to an airtight container.
• Homemade fresh pasta should be dusted with flour to prevent sticking and stored in an airtight bag or container in the refrigerator.
• If you want to freeze homemade penne pasta, dust it with flour and lay it out on a baking sheet separated so they don't stick together. Freeze for a few hours until hard then transfer to a zip top bag and back to the freezer. To use, boil wtihout thawing to prevent it turning mushy.
