The Science Of Yogurt Expiration
Yogurt is undoubtedly one of the most popular and healthy dairy products around the world. Many people enjoy it as a quick breakfast or snack option due to its delicious taste and versatility.
However, have you ever been in doubt about whether you can eat the yogurt that has been sitting in your fridge for a while now?
Well, today, we are going to explore one of the most common questions people have regarding yogurt: does yogurt go bad?
We are going to specifically focus on the science behind yogurt expiration and answer some of the frequently asked questions about this topic.
What Causes Yogurt To Expire?
Yogurt contains live cultures as its main ingredient, which can influence its shelf life and cause it to expire.
Below are the different factors that can cause yogurt to expire:
- Bacterial action: Since yogurt is a live cultured product, bacteria play a significant role in making it what it is. However, over time, the bacteria responsible for fermenting the milk begin to diminish, and others take their place, which can cause the yogurt to spoil.
- Temperature: Higher temperatures can cause the yogurt’s live cultures to die off, resulting in it getting spoiled faster.
- Exposure to air: Contact with air can cause the active bacteria cultures in the yogurt to die and result in a sour smell that may not be suitable for consumption.
How Does Expiration Affect The Taste And Texture Of Yogurt?
The expiration of yogurt can cause changes in its taste and texture.
Here’s how:
- Sour taste: Expired yogurt typically has a sour taste and an unpleasant smell. It results from the breakdown of lactose in the milk by bacteria, leading to the formation of lactic acid.
- Separation: When yogurt goes bad, the liquid begins to separate from the solid, resulting in a lumpy and watery texture.
- Moldy growth: If you notice mold growing on the surface, it’s an indication that the yogurt has expired and should be discarded.
How Long Does Yogurt Last Before It Expires?
The shelf life of yogurt depends on several factors such as the manufacturing date, storage temperature, and the presence of preservatives. However, with proper storage at a consistent low temperature, yogurt should last for the following durations:
- Unopened yogurt: An unopened yogurt container stored in the fridge should last for at least 7 to 10 days past its printed sell-by date.
- Opened yogurt: Once you’ve opened the yogurt container, it can last for 5 to 7 days if it’s stored correctly in the fridge.
Yogurt can expire, and consuming expired yogurt can have adverse effects on your health. Always check the expiry date before consuming yogurt and note that several factors can lead to it expiring.
Remember to store the yogurt at consistent low temperatures and consume it within the recommended time frame.
Signs Of Expired Yogurt
Does Yogurt Go Bad?
Yogurt is a healthy and nutritious dairy product that can be enjoyed in many different ways. However, like all food items, yogurt can go bad after a certain period of time. In this blog post, we will explore the signs of expired yogurt and what you should do if you find that your yogurt has gone bad.
Identifying The Signs Of Expired Yogurt
One of the most important things to keep in mind is the expiration date. Most yogurt containers come with an expiration date that you should check before consuming. Even if it hasn’t reached its expiration date, yogurt can still go bad due to factors such as poor storage conditions.
When your yogurt has gone bad, you can identify the following signs:
- Foul or sour smell
- Significantly changed texture

Examining The Texture And Smell Of Yogurt
When opening your yogurt container, check for any evident changes. Expired yogurt may have a thick and lumpy texture, which is a clear sign that it has gone bad. Additionally, an unusual and sour smell can indicate the breakdown of the yogurt.
If you are in doubt, do not taste it, as it may cause food poisoning.
The Appearance Of Mold: What To Look For And What It Means
The presence of mold is a clear sign that the yogurt has gone bad. Inspect your yogurt for any unusual discoloration or specks on the surface. If you find mold, do not eat the yogurt, as it may cause foodborne illness.
Moreover, mold is capable of spreading through the entirety of the yogurt container. So, if you spot any mold on the surface, discard the whole container.
So, next time you are wondering if the yogurt is still good, check the expiration date, smell, texture and mold growth.
Remember that expired yogurt can cause various health problems, so make it a habit to store it correctly and always check it before eating.
