Hummus is a delicious, creamy dip made from chickpeas, tahini, lemon juice, garlic, and olive oil. It is a popular dish enjoyed as a spread, dip, or ingredient in many meals. Like other fresh food items, hummus does not last forever, and its shelf life depends on whether it is store-bought or homemade. Store-bought hummus usually contains preservatives, which allow it to last longer than homemade versions. Unopened store-bought hummus typically stays fresh in the refrigerator for up to two months past its production date if stored correctly.

Signs Your Hummus Has Gone Bad

Recognizing when hummus has gone bad is important to avoid foodborne illnesses. Look out for the following signs:

• Mold Growth: Visible mold or dark spots on the surface are clear indications that the hummus has spoiled and should be discarded immediately.
• Unpleasant Smell: Fresh hummus has a mild, nutty aroma. If you notice a sour, rancid, or otherwise unpleasant odor, it is no longer safe to eat.
• Color Changes: If the hummus becomes darker, takes on a grayish hue, or shows any unusual color, it is likely spoiled.
• Separation of Ingredients: Although some oil separation is normal, excessive liquid pooling combined with other signs of spoilage means the hummus is past its prime.
• Change in Texture: Spoiled hummus may develop a slimy or overly dry texture, indicating it is not safe for consumption.

Factors That Affect Hummus Shelf Life

Hummus's shelf life can be influenced by several factors, including:

• Storage Temperature: Storing hummus at the proper temperature of 40°F (4°C) or lower is crucial. Warm temperatures accelerate bacterial growth, leading to faster spoilage.
• Exposure to Air: When hummus is not properly sealed, exposure to air can cause it to dry out or allow bacteria to grow, reducing its shelf life.
• Use of Utensils: Using unclean or previously used utensils to scoop hummus can introduce bacteria and contaminants, hastening spoilage.
• Type of Hummus: Flavored hummus varieties, such as those with roasted garlic, red pepper, or other add-ins, may spoil faster than plain hummus because of the added ingredients.
• Preservatives: Store-bought hummus often contains preservatives, which help it last longer than homemade versions.
• Initial Freshness: If hummus is close to its expiration date when purchased or made, it will not last as long as fresher batches.

Best Practices For Storing Hummus

To maximize the freshness and safety of hummus, follow these best practices:

• Keep Refrigerated: Always store hummus in the refrigerator at or below 40°F (4°C). Avoid leaving it at room temperature for extended periods, as bacteria can grow rapidly.
• Use Airtight Containers: Transfer hummus to an airtight container if it doesn’t come in one. This minimizes exposure to air and reduces the risk of contamination.
• Clean Utensils Only: Always use clean utensils to scoop out hummus. Avoid double-dipping or using dirty spoons, which can introduce harmful bacteria.
• Store Away from the Door: Store hummus in the main compartment of the refrigerator rather than the door, where temperatures fluctuate more.
• Consume Quickly: Even with proper storage, hummus should be consumed within its recommended time frame to enjoy it at its best.

Does Homemade Hummus Last As Long As Store-Bought?

Homemade hummus does not last as long as store-bought hummus because it does not contain preservatives. While store-bought hummus can stay fresh for up to 7 days after opening, homemade hummus typically lasts only 4 to 5 days, even when stored properly in the refrigerator. To extend the shelf life of homemade hummus slightly, use very fresh ingredients and ensure it is stored in an airtight container. Adding a thin layer of olive oil on top before sealing can help protect it from air exposure.

Can You Freeze Hummus To Extend Its Shelf Life?

Yes, you can freeze hummus to extend its shelf life. Freezing hummus can keep it fresh for up to four months. However, freezing may alter its texture, making it slightly grainy or less creamy when thawed. To freeze hummus:

• Use Airtight Containers: Transfer hummus to a freezer-safe, airtight container. Leave some space at the top, as hummus expands slightly when frozen.
• Add Olive Oil: Drizzle a thin layer of olive oil over the surface of the hummus before sealing the container. This can help preserve its flavor and texture.
• Label and Date: Label the container with the date of freezing to keep track of its storage time.
• Thaw Safely: When ready to eat, thaw hummus in the refrigerator overnight. Stir it well to restore consistency before serving.

Keep in mind that while freezing can extend shelf life, it’s best to consume hummus as fresh as possible for optimal flavor.

What Happens If You Eat Expired Hummus?

Eating expired hummus can be risky and may lead to foodborne illnesses. The most common symptoms of consuming spoiled hummus include:

• Nausea: A queasy feeling in the stomach after eating spoiled food.
• Vomiting: Expired hummus can cause the body to reject it as a defense mechanism.
• Diarrhea: Bacterial contamination in spoiled hummus can lead to digestive distress.
• Stomach Cramps: Spoiled food often triggers uncomfortable abdominal pain or cramping.
• Food Poisoning: In severe cases, eating spoiled hummus can lead to food poisoning caused by bacteria such as Salmonella or Listeria.

To avoid these risks, always inspect hummus for signs of spoilage and adhere to recommended storage times.

How To Properly Seal And Store Hummus Containers

Properly sealing and storing hummus containers helps keep it fresh and safe to eat. Follow these steps:

• Seal Tightly: After each use, ensure the lid of the container is securely closed. If the original packaging is damaged, transfer the hummus to an airtight container.
• Store in the Coldest Part of the Fridge: Place hummus in the back of the refrigerator where the temperature is most consistent and cold. Avoid storing it in the door, as this area experiences temperature fluctuations.
• Minimize Exposure: Avoid leaving hummus uncovered for extended periods during serving, as this can lead to drying and contamination.
• Portion Control: Scoop out only the amount of hummus you plan to eat at a time, rather than eating directly from the container. This prevents bacteria transfer and keeps the rest of the hummus fresh.
